-
- 1. (IND) wall to insert opening
- 2. (Y/N) confirm choice
- 3. (Y/N) option: y - rectangle-shaped, n - pre-designed opening <y>
- if `n' is replied:
- 4. (CHAR) pre-designed opening name (8 chars.)
- for all options:
- 5. (NUM) opening width (greater than 0)
- 6. (NUM) height of opening (0 or greater)
- 7. (NUM) height above floor (0 or greater)
- 8. (POINT) opening position (Alt+1 - change opening orientation)
- if opening is from the General Opening Library (L$OPEN) and one or
- more combinations exist for the wall/opening and specified direction:
- 9.* (Y/N) solution acceptable?
- if `n' is selected repeatedly:
- 10. (Y/N) all options were introduced, wish to loop again?
- for all options:
- 11.*(Y/N) y-another position, n-another wall, <ENTER>-displacement
- if ENTER is pressed:
- 12. (POINT) start of displacement (fixed point in model)
- 13. (POINT) end of displacement (point on opening)
- 14. (NUM) displacement

- Description
- This command places openings in multi-layer walls. If an opening has
- previously been selected during the current work session, that opening is the
- default and will be placed by this command. If no opening has been selected,
- or an opening other than the default is to be placed, it is necessary to
- access this command via the graphic library of openings, i.e., the pull-down
- menu, or specify the library and opening name using the \setob command.
-
- From the CREATE sub-menu in the pull-down menu select:
- * MULTI-LAYER WALLS
- * PICK LIBRARY OPEN.
-
- A list of libraries appears on screen. Select the library that you require.
- A graphic menu, together with the opening name and width, appears on screen.
-
- NOTE: Only openings in the General Opening Library may have independent end
- conditions attached to them (using the \clib command). Openings in other
- libraries may include the termination of the wall in which they will be
- inserted as an integral part of the opening but they will not behave as end
- conditions (replace, etc.).
-
- Openings that form part of a combination do not appear with end conditions
- attached in the graphic library, but if end conditions have been combined with
- the opening (using the \clib command) they will appear when the opening is
- placed in the wall.
-
- Using the Cursor to Select the Required Opening
-
- Indicate the wall in which you wish to insert the opening and confirm that the
- system has identified the intended wall. You are asked whether the three
- dimensional opening is to be a simple rectangular void or a specially
- pre-designed one. If you select a rectangular void it will adopt the
- thickness of the wall.
-
- If you select a special pre-designed opening, specify its name. It can be any
- negative solid. It can be created as a 1 x 1 x 1 unit that the system will
- stretch to the specified width and height, and wall thickness. Alternatively,
- it may be created with real dimensions (except for thickness which should be 1
- unit). In this case, the width and height must be specified as `1' in order
- to maintain the original dimensions.
-
- If the opening was defined as a stretchable opening when included in the
- opening library (using the \olib command) you are asked to state the opening
- width. State the opening height and starting height above the floor.
-
- The opening appears attached to the cursor in the indicated wall so that it is
- free to "slide" along the length of the wall.
-
- Changing the Symmetry of the Opening
-
- At this stage you may switch the symmetry of the opening. Use <Alt>+1 to
- switch between the four possible symmetries (left, right, inward opening,
- outward opening).
-
- The cursor is attached to the opening at one of its sides. If you wish to
- switch the cursor to the other side, press <Alt>+2.
-
- Point to the desired position. The wall will be broken and the opening will
- be placed in the position you indicated.
-
- If the opening has been selected from the General Openings Library, it will
- appear together with the combined end conditions that were specified using the
- \clib command. You will be asked if the solution is acceptable.
-
- If you reply negatively, the next combination will be displayed. If you
- continue to reply negatively the system will inform you when all the
- combinations in the library have been exhausted and ask you whether you wish
- to repeat the cycle. If no combination (for the wall/opening and direction)
- has been defined, the opening will be placed as it exists in the General
- Opening Library (L$OPEN) and the system end conditions (straight lines) will
- be attached. If you do not wish to repeat the cycle you will end the command.
-
- Where the opening/end condition combination that is being placed has been
- defined (using the \clib command) for a symmetrical wall (i.e., symmetrical
- layer colors as well as layer thickness) you will be able to switch the
- symmetry of the opening between four possible symmetries, i.e., left, right,
- inward opening, outward opening). All combinations are available regardless
- of opening direction.
-
- For asymmetrical walls, combinations must be created for both inward and
- outward opening directions (using the \clib command). When you place the
- opening, you determine the symmetry using the <Alt>+1 keys. Depending on the
- direction of the placed opening (inward or outward), the system will present
- you with combinations in that direction only.
-
- The system will prevent you from placing an opening in a position that
- projects beyond the end of the wall.
-
- You are now presented with three options. You may place another of the same
- opening in the same wall, in another wall, or you may specify an accurate
- displacement for the opening you have just placed.
-
- If you select this option you will be asked to indicate two points; one on the
- model and one on the opening. The system will return the exact distance
- between these two points in the command line. If the distance or displacement
- is not satisfactory you may change it. When you enter the new value, the
- opening will move to the new position so that the displacement between the two
- points will be exactly that which you specified.
-
- You are presented with the three previous options repeatedly until you select
- a new command.
-
- NOTE: The maximum number of openings allowed in a single wall is 30.
