An Introduction to TinyCAD



Welcome to TinyCAD!

You can get the latest news, release and source code from the Sourceforge site. Go to http://tinycad.sourceforge.net.

TinyCAD is an open source schematic capture program. Use TinyCAD to draw your own circuit diagrams.

You can lay out circuit diagrams using the supplied libraries. Alternatively, there is a component library editor built into TinyCAD – so you can easily create your own symbols. You may also find more libraries on the Sourceforge site that other users have release under the GPL license for you to use.

Once you have drawn your design, you can use the special functions to automatically add symbol references, check your design against rules of correctness and create a parts list. TinyCAD can also export a netlist for import into a PCB layout program.

Once you have your design you can copy and paste it into other packages such as Word (or better still OpenOffice). You may also print your design to any supported Windows printer. If your design is larger than a single page then it can be either scaled to fit on a single page or printed across many pages.



Changes since version 1.95.20

Welcome to TinyCAD version 2.00.00. Here is a quick summary that has changed in this release:

New features:
Each single drawing file can now be made up of multiple sheets (just like Excel).
Screen re-drawing has been improved to reduce flicker
Save as a black & white bitmap and select the scaling factor
Autosave every “n” minutes


New library editing features:
Library Symbols can now have multiple names
Export and import single library symbols or the entire library into an XML file
Right click on a symbol in the thumbnail view to get direct access to the symbol's properties
Multi-sheet tabs make multiple part per package symbols easier to draw




Changes since version 1.90.00

Welcome to TinyCAD version 1.95.20. Here is a quick summary that has changed in this release:

New features:
Change the colours of the drawing items such as pins and wires
A new “Windows” menu option to navigate between your open windows
“Make horizontal” & “Make vertical” menu options for wires
Increased zoom on drawings


Integrate more easily with other programs
TinyCAD now loads and saves it's files in an XML file format
Save as a PNG file for sharing your designs with others
Output a netlist for common PCB programs, including PADs and Protel


Improved symbol & library editing:
Copy symbols from one library to another
New context (right-click) menu on library thumbnails for faster library editing
Pins have even more options to make them look better

Improved features:
The Undo/Redo has been completely re-written to make it more robust
The dragging of wires and symbols has been re-worked at length to improved ease of use

.. and numerous bug fixes to improve stability and make TinyCAD easier to use!



Changes since version 1.80.00

Welcome to TinyCAD version 1.90.00. Here is a quick summary that has changed in this release:

New symbol picker tool
The most obvious change to TinyCAD when you fire it up is the new symbol picker that sits on the left hand side of the screen. This replaces the old way of fetching symbols from the libraries.


New library format
The Libraries are now stored in Microsoft Access database format. This means all new libraries will have an extension of .mdb and can be opened by a copy of Access. This change to a more standard format for storing libraries will make it much easier to add new features to the libraries in future, and will enable 3rd parties to write their own tools to read/modify the symbols.

The first new feature with the new library format, is that you are able to select the default orientation of symbols when they are picked. This fixes a long running bug in TinyCAD that symbols were drawn one way round, but always extracted from the libraries rotated.

To convert your libraries to the new format, use the new “Upgrade” button in the library dialogue box.


Lots of bug fixes
In line with all new releases I have been busy fixing bugs. There are a few crashes fixed and some tiding up of the way editing drawings work.
