2. Welcome to PowerCAD
Welcome to PowerCAD. PowerCAD gives you the power to design schematics
starting from the initial idea to the final drawing. These are just a small
description of the kind of schematics you can do with PowerCAD:
* hydraulics,
* pneumatics,
* ladder,
* electrical,
* grafcet,
* HVAC.
2.1. How PowerCAD Works
When you start working on a drawing, you'll usually begin by deciding on the
components you're going to place on the drawing. To place components on the
drawing you can either choose them from the symbol menu or import them from
an already defined block.
PowerCAD is versatile. You can define components that are not supplied in the
standard menu, and with these components you can define as many blocks as
you want.
As you build the diagram, you'll have to connect symbols together. The ROUTER
will help you to connect the pieces together. The ROUTER is an intelligent
piece of software that will permit you to optimize the flow of lines between
CONNECTION POINTS.
You'll have the possibility to move, rotate, flip, delete components from the
drawing. These operations will trigger the ROUTER to optimize again the flow
of lines.
You'll have the possibility to see your drawings at any scale you want with
the ZOOM commands.
When you want to have a copy of your drawing, just select the command PRINT
and you'll obtain a print of the drawing and/or the PART LIST.

Powercad User Manual
5.2.1. The Status Line
On the status line, you will find information about:
* the free memory, (100% when you start)
* the operation you are doing,
* the position of the mouse. (X,Y)
If you look at the free memory index during the construction of a
schematic, you will notice it decreasing. The maximum number of
components you can put on a drawing is 1000 (if all the memory is
availiable for the schematic).
5.2.2. The Menu
In the menu you will find the command that you can select to produce a
drawing. To select a command, just move the mouse to a menu item,
you will see a yellow box around the command you are pointing at, and
click on the mouse.
You can't select the dashes in the menu. We have put dashes in the
menu to make logical groups of commands.
5.2.3. The Work Area
The whole screen is the work area. When you select a command from the
menu, the menu disappear. You can use the whole screen to make your
schematics.

Powercad User Manual
5.3. Getting Started
The first step to creating a schematic is to load an existing drawing, and
make modification on it, or create a new one.
5.3.1. Opening an Existing Drawing
If you want to load an existing drawing you must:
1. select LOAD in the menu,
2. select the name of the file in the file selector,
3. click on the name of the file you want.
Note: When you scroll in the file selector, the drawing you are pointing
to with the mouse is shown in the preview box at the right of the
screen.
At any time, you can cancel the LOAD operation by pressing the right
mouse button.
[Figure 2 Loading a File]

Powercad User Manual
5.3.2. Starting a New Drawing
If you want to start with a new page you must:
1. select LOAD in the menu,
2. select the NEW.#00 in the file selector,
3. click on.
Note: NEW.#00 is a drawing file with nothing inside. When you load it,
you are erasing all the working memory. If you don't have this
file, you can create it by saving an empty drawing.

Powercad User Manual
5.4. Zooming and Panning
Zoom is like a magnifying window you move on the drawing. To see more of the
drawing, but with less detail, you must reduce the zoom scale. To zoom on a
specific detail, you will have to increase the zoom scale.
When PowerCAD starts, the zoom factor is equal to 1 and the coordinate of the
lower left corner of the screen is set to 0,0 and is called the origin. You
can modify the zoom factor and the coordinate of the lower left corner with
the four zoom commands.
The four zoom commands are:
* PAN
* ZOOM ALL
* ZOOM SCALE
* ZOOM WINDOW
PAN
The PAN command will change the position of the viewing window on the current
display. You will have to designate two points with the mouse. The first
point is the starting point for the displacement. The second point is the
destination point. When you have selected the two points, PowerCAD will
regenerate the drawing.
Note: The selection of the second point is made by dragging the mouse to
the destination point.
ZOOM ALL
When you select the ZOOM ALL command, PowerCAD will regenerate the
drawing to display the entire drawing in the largest scale possible while
still fitting it on the screen.
ZOOM WINDOW
When you select the ZOOM WINDOW command, you will have to designate two
points with the mouse. The first point is the first corner of the window.
The second point is the other corner of the window. When you have selected
the two points, PowerCAD regenerates the drawing by fitting the window you
have selected inside the screen.
Note: The selection of the second point is made by dragging the mouse to
the second corner of the window. You will see a dotted box enclosing
the view area to zoom.
10
Powercad User Manual
ZOOM SCALE
With the ZOOM SCALE command, you can directly input the zoom factor for the
drawing. After you have selected the command, you will see a dialog box where
you will input the new zoom factor. The value you will enter is a relative
value. If you enter 0.6 you will reduce the zoom factor to 60% of the
previous value. If you enter 2.3 you will multiply the zoom factor by 2.3.
[Figure 3 ZOOM SCALE]
5.5. Saving a Drawing
If you want to save the drawing you are working on, you must:
1. select SAVE in the menu,
2. type the name of the file in the dialog box.
The name of the file can have up to eight characters. The extension is
automaticaly given by PowerCAD. As an example when you first save a drawing,
you give it the name "ABCD". PowerCAD will append to the drawing the
extension "#00". The second time you give a drawing the same name,
PowerCAD will append the extension "#01". The third time the extension will
be "#02"...
11
Powercad User Manual
5.6. Quitting PowerCAD
If You want to quit PowerCAD, select Quit in the menu. When you quit,
PowerCAD will save a copy of the drawing you are working on. The name of the
backup copy is "QUIT.###". This file is always overwritten by a new one when
you quit PowerCAD.

Powercad User Manual
6. Adding and Editing Components
In this section are the commands you can use to make your schematics. These
commands work with the intelligent ROUTER to give you the highest performan-
ce in your CAD work.
6.1. Adding
Adding components to the drawing is like adding real components in a control
pannel or an assembly. PowerCAD see the components as components and not
as a group of lines. If you select the single acting cylinder, PowerCAD will
know it is drawing a single acting cylinder and also where the insertion point
and the connection point are in the drawing.
6.1.1. COMPONENTS
When you want to insert a new component in the drawing, you must select
COMPONENTS or CUSTOM SYMB. We give you a standard library of
200 components you can use. If you need components who are not there,
you can create them with the program SYMBOL. You can create 200
symbols and use them in your schematics.
After you have choosen the command, a graphic menu will display 25
symbols on the screen. To select one of them, just select the symbol with
the mouse. The menu will dissappear and you will see the component
drawn in shadow on the screen. Move the component to its insertion,
point and click the mouse. After you have inserted the component you
will see another component in shadow. If you want to insert it, just move
it to its insertion point and click the mouse. If you don't want it, just
cancel with the mouse.
If the component you want is not on the graphic menu, you can scan the
pages of the menu with the number keys 1-8. When you press on 1,
you will see what is on page 1.
As you add components to the drawing, you will note a number that is
inserted near the component. This number shows the uniqueness of the
component. Each component has a number and it cannot be repeated.
Two components can't have the same number.
Special note: If you pick a connection point (the symbol made with a
filled circle on pages 2 and 6 of the menu) and you place it
over a line, the line will be broken into two parts and the
two parts will be connected to the new connection point that
you have just inserted.
13
Powercad User Manual
6.1.2. TEXT
You can insert text to add information to your drawing. A string of text is
treated like a component of the schematic. To add text to the drawing,
select the TEXT command.
The first thing to do is to click the mouse where you want to insert text.
Afterwards you will see a dialog box in which you will input the text you
want to display along with the size. The maximum length of the text is 20
characters and you can input letters, numbers and special characters.
There is no restriction on the size.
You can cancel the command with the right mouse button.
[Figure 4 TEXT command]
6.1.3. LINE
This command shows you the power of PowerCAD. The LINE command
uses one of the most powerful piece of drawing software you have seen
until now, we call it the ROUTER. To select, go on the LINE command
and click the mouse.
14
Powercad User Manual
To connect two components, just point the mouse near the first
connection point and click. You don't need to be on the point, the
ROUTER will find the nearest point. You will see a shadow line between
the first connection point and the mouse position. Go near the second
connection point and click the mouse.
The ROUTER draws two lines. The first line goes horizontally from the
first connection point to the horizontal position of the second connection
point. The second line goes vertically from the second connection point
to the vertical position of the first connection point. If you invert the
order of selection of the connection points, you obtain a different path for
the line.
The ROUTER selects the kind of line it must draw. If the two connection
points are of the power type, the ROUTER draws a full line. If one of the
point is of the pilot type, the ROUTER draws a dashed line. The ROUTER will
not connect mixed types of connection points, like electrical type and power
type.
The ROUTER will generate all the loop for lines passing over other lines.
[Figure 5 LINE command]
15
Powercad User Manual
6.2. Editing
The editing commands act upon components allowing them to be moved,
deleted, rotated, flipped, scaled, colored or combinations thereof. These
commands work in combination with the ROUTER so you can quickly see the
results of you action on the lines and the network.
6.2.1. MOVE
This command translates the selected component into a new position. To
move a component:
1. select MOVE in the menu,
2. go onto the component you want to move and click the mouse,
3. move the component to the new location and click the mouse,
4. go onto another component you want to move or cancel with the mouse.
Shadow moving occurs with the movement of the selected component.
when you click the mouse on the new location of the component, you will
see a regeneration of the drawing to update the new positions of the
connecting lines. You can't move lines alone.
[Figure 6 Moving a component]

Powercad User Manual
[Figure 7 Regenerating the drawing after MOVE]
6.2.2. FLIP
This command will cause the selected component to be flipped across the
vertical axis. To flip a component:
1. select FLIP in the menu,
2. go onto the component you want to flip and click the mouse,
3. go onto another component you want to flip or cancel with the mouse.
You can't FLIP TEXT.
6.2.3. ROTATE
This command will cause the selected component to be rotated 90
degrees counter-clockwise. To rotate a component:
1. select ROTATE in the menu,
2. go onto the component you want to rotate and click the mouse,
3. go onto another component you want to rotate or cancel with the
mouse.
17
Powercad User Manual
6.2.4. SCALE
This command will cause the selected component to be scaled to one of
the seven standard scale factor { 8, 4, 2, 1, 1/2, 1/4, 1/8 }. To scale a
component:
1. select SCALE in the menu,
2. go onto the component you want to scale and click the mouse,
3. go onto another component you want to scale or cancel with the
mouse.
When you SCALE a component, PowerCAD will double the size of the
component. When the component is eight times bigger than the standard
size and you try to scale it, the component will be sized at 1/8 of standard
size. Part number is shown only when the scale of the components is
equal to 1.
If you want to SCALE TEXT, see the command EDIT.
[Figure 8 Edit commands]
18
Powercad User Manual
6.2.5. COLOR
This command will cause the selected component to be colored with one
of the sixteen standard colors { Black, Blue, Green, Cyan, Red, Magenta,
Brown, Light Gray, Dark Gray, Light Blue, Light Green, Light Cyan, Light
Red, Light Magenta, Yellow, White }. To color a component:
1. select COLOR in the menu,
2. go onto the component you want to color and click the mouse,
3. go onto another component you want to color or cancel with the
mouse.
When you COLOR a component, PowerCAD will scroll through the sixteen
colors to assign the color to the component.
6.2.6. DELETE
This command will cause the selected component to be deleted from the
schematic. To delete a component :
Be sure of what you are doing, because there is no UNDO
command.
1. select DELETE in the menu,
2. go onto the component you want to delete and click the mouse,
3. go onto another component you want to delete or cancel with the
mouse.
Lines who connect to the component you DELETE will also be deleted.
If you want to delete a LINE, go onto the point where the line bends and
click the mouse.

Powercad User Manual
7. Using blocks
Blocks are standard circuits that enclose symbols and connecting lines. With
blocks you can design complex schematics from standard circuits. Blocks are
easy to create and manipulate and they give you the power to customize your
working environment.
7.1. Loading a Block
Loading a block is like loading a file ,except that you don't erase the
working memory. It is a merge of the block and the schematic in the working
memory.
If you want to load a block you must:
1. select BLOCK LOAD in the menu,
2. select the name of the block in the file selector,
3. click on the name of the file you want,
4. select the insertion point of the block.
Notes: When you scroll in the file selector, the block you are pointing to
with the mouse is shown in the preview box at the right of the screen.
At any time, you can cancel the BLOCK LOAD operation by pressing
the right mouse button.
7.2. Saving a Block
Saving a block gives you the opportunity to save standard circuits as building
blocks for bigger schematics. It increase your design speed.
If you want to save a block, you must:
1. select BLOCK SAVE in the menu,
2. type the name of the file in the dialog box,
3. you select the block you want to save by dragging the mouse over it,
4. you put the mouse where you want the insertion point and click on the
mouse.
The name of the file can have up to 8 characters. The extension is
automaticaly given by PowerCAD. The extension is "CIR".

Powercad User Manual
8. The Function Key Commands
We have included four commands you can access through the function keys.
These commands have been put in the function keys because they are used less
often than the commands in the menu.
8.1. Grid
The grid is visibly represented by a dot at each 1/8" in the horizontal and
vertical directions. The grid can be turned on and off by hitting the [F7]
key when the menu is on the screen. When the zoom is too small, PowerCAD
doesn't generate the grid.
8.2. Loop
The ROUTER put loops automatically over wires and lines who cross each other
but are not connected. The loops can be turned on and off by hitting the [F8]
key when the menu is on the screen.
8.3. Part Number
Part number are automatically generated by PowerCAD. The part number is
shown with the component on the schematics. You may turned this representa-
tion on and off by hitting the [F9] key when the menu is on the screen.
8.4. DXF Transfer
This command allows you to transfer the schematic you work on in a format
other CAD can read. The standard we use for the transfer is the Data Exchange
Format or DXF. To transfer the schematic you are working on:
1. press the [F10] key,
2. enter the name of the file in the dialog box.
Notes:
* The extension ".DXF" is automatically appended to the name of the file.
* You can export DXF file but you can't import a DXF file in PowerCAD.
If you want to import a DXF file in PowerCAD, you must use SYMBOL to
convert the DXF file to a symbol you can use with PowerCAD.
22
Powercad User Manual
9. New Symbols
PowerCAD comes with 200 standard symbols. Some of the symbols are for
electrics, ladder or GRAFCET, but the majority of them are for fluid power.
We could not include all the symbols you might encounter in your field, so we
give you the opportunity to create your own custom symbols. You can create
200 symbols, and use them in your schematics.
9.1. Designing Custom Symbols
To design custom symbols you need the symbol editor named SYMBOL.
SYMBOL is a small CAD with only the basic drawing functions. You can draw
circle, arc, line, arrow. You can also import the entities part of DXF files you have
made with AutoCAD or any other CAD which produces DXF files.
9.1.1. The SYMBOL Screen
The working area of SYMBOL is 3.25"x2.5". It give you a lot of space to
design complex symbols. At the upper right corner of the screen, you will
see the coordinates of the position where the mouse is pointing. You also
have a grid to help you do the design of your symbols.
[Figure 9 The SYMBOL Window]

2. click the mouse on the first point of the line,
3. drag the mouse to the second point of the line,
4. when you have finished drawing lines, cancel with the mouse.
24
Powercad User Manual
9.1.1.4. Arrow
The fourth tool is the arrow. With the arrow, you will produce straight lines
at any angle on the screen, and on one side of the line you will get an
arrow. You can have up to 50 arrows in a symbol.
To draw an arrow:
1. select the arrow symbol in the menu,
2. click the mouse on the first point of the arrow,
3. drag the mouse to the second point of the arrow (on this side you will
see the tip of the arrow),
4. when you have finished drawing arrows, cancel with the mouse.
9.1.1.5. Fill
The fifth tool is the fill. The fill gives you the opportunity to put a plain
fill in a part of the symbol. The part you put the fill in must be closed.
If it is not closed, your are going to fill the whole symbol and the schematic.
You can have up to 50 fills in a symbol.
To fill a part of the symbol:
1. select the fill symbol in the menu (the box filled in white),
2. click the mouse in the region you want to fill (it must be a closed
region),
3. when you have finished filling, cancel with the mouse.
9.1.1.6. Selection
The selection box (the box with the two lines inside) must be used at two
different times when you edit a symbol. The first time you use it is to
select the symbol you want to edit. Symbols are shown in group of 25.
If the symbol you want to edit is not in the graphic page, you can scan the
pages of the menu with the number keys 1-8. When you press on 1,
you will see what is on page 1. If the symbol you want to edit is on the
page, select it with the mouse.
The second time you will use the selection box is to save the symbol you
are editing. Just click on the selection box and your symbol will be
automatically saved in the symbol library.

Powercad User Manual
9.1.1.7. Line Type
When you have lines in the symbol, you can change their types. SYMBOL
gives you nine line types to choose from. To change a type of line:
1. click on the line type you want,
2. click on the line you want to change,
3. when you have finished, cancel with the mouse.
You can only change the type of lines. You can't change circles, arcs or
arrows.
9.1.1.8. Base Point and Connection Points
Base point and connection points are the most important part of a
symbol. They give information to PowerCAD about where and how the
component must be drawn and to the ROUTER about where the lines
must connect.
Each symbol has a base point and it can't have more than one. The
base point tells PowerCAD where to insert the component in the
schematic. When you insert a new component or you move one on the
drawing, it is the base point who tells PowerCAD where to draw the
component in the drawing. If you want to move the base point of the
symbol:
1. click on BASE POINT,
2. click on the symbol where you want to put the base point.
A symbol can have up to 50 connection points. Connections points
are used by the ROUTER to connect lines between components. You
must assign a type to a connection point. Types are:
* power (pwr),
* fluid control (plt),
* electrical (ele).
If you don't assign connection points to a component, it will be
impossible to connect lines to it. If you want to assign a connection point
to a symbol:
1. click on the kind of connection point you want,
2. click on the symbol where you want to put the connection point,
3. when you have finished, cancel with the mouse

9.1.1.9. Delete
This command will cause the selected object to be deleted from the
symbol. To delete an object :
Be sure of what you are doing, because there is no UNDO
command.
1. select DELETE in the menu,
2. go onto the object you want to delete and click the mouse,
3. go onto another object you want to delete or cancel with the mouse.
9.1.1.10. Quit
When you have finished designing with SYMBOL, select QUIT in the
menu. When you quit, SYMBOL will update the symbol library, so it is
important to leave the editor by the QUIT command.
9.2. Importing DXF Files
If you want to import a symbol you made with AutoCAD, or any other CAD, you
must save it with the DXF function of the CAD. Try to limit the dimension of
the symbol to 2 drawing units.
When you are in SYMBOL, press on [F10] and select the name of the file in the
file selector.
9.3. Using Custom Symbols
SYMBOL gives you a lot of power, you can design your own symbols and add it
to your schematics. If you don't like a symbol in your drawings, you can
change its representation with the SYMBOL editor and it will be updated in all
your schematics and blocks. If you combine the custom symbols capacity with
the block features you will see a noticeable increase in your productivity.
It is very important that everybody, who uses PowerCAD, uses the same custom
library. If you don't, you will not be able to share your drawings. The
custom library is part of the schematics you make, if you send your drawings
to others, and you use custom symbols in drawings, you must also send your
library : "PIECEA.HYD" and "PIECEB.HYD". If you don't, it will be impossible
to regenerate the schematics.
27
Powercad User Manual
As powerful as the software is, we recommend that you make a backup copy of
your library before you make any changes on custom symbols. The name of the
files you must backup up are "PIECEA.HYD" and "PIECEB.HYD".

10. Printing
Printing drawings is very important. PowerCAD gives you the opportunity to
print drawings and documentations that goes with them.
The drawing documentations are:
* Parts List,
* Purchase Order List.
10.1. Choosing a Printer
PowerCAD support 3 kinds of printer; 9 pins, 24 pins and HP LASERJET. If you
have a 9 pins or 24 pins, it must be in EPSON or IBM PROPRINTER emulation.
PowerCAD default printer operation is on 9 pin printer. If you want to use
PowerCAD with another kind of printer you must add a software switch when you
call it.
If you are using a 24 pins printer start PowerCAD with this line :
POWERCAD P:24
If you are using a laser printer start PowerCAD with this line :
POWERCAD P:L
10.2. Printing a Drawing
To print a drawing:
1. put what you want to print on the screen (with the zoom commands),
2. select PRINT in the menu,
3. fill the dialog box with the informations of the drawing
(at PART LIST enter N).
Note: If you want to cancel the PRINT command, just press the right button
of the mouse and continue to press until it stop.

10.3. Printing Documentation
To print the documentation of the schematic:
1. select PRINT in the menu,
2. fill the dialog box with information about the drawing
(at PART LIST enter Y).
10.4. Adding Information to the Drawing
If you want to print a good documentation of your schematic, you will have to
add information on the components you want to put on the documentation.
To add information to a component:
1. select EDIT in the menu,
2. go onto the object you want to edit and click the mouse,
3. enter information in the dialog box,
4. go onto another object you want to edit or cancel with the mouse.
You must also add information to the file "PART.DAT". This file is an ASCII
file and you can edit it and add information to it. The information you will
find in "PART.DAT" are:
1. manufacturer,
2. part number,
3. description,
4. cost of the component,
5. the sell price of the component.
The manufacturer can have up to eight characters and the part number can
have up to twenty characters. There are no restrictions on the other fields.
All the fileds must be seperated by a comma ",".
