- 1. (Y/N) expand along z? <y>
- if reply is `y'
- 2. (NUM) height of polygon (on z-axis)
- if reply is `n'
- 2. (Y/N) expand current polygon ? <y>
- 3. (POINT) expand from point
- 4. (POINT) expand to point
- if reply to prompt 2 is `n'
- 5. * (IND) polygon to expand
- 6. * (Y/N) confirm choice
- for all options
- 7. (Y/N) create a POSITIVE solid? <y>

- Description:
- This command turns a polygon into a solid prism with two parallel identical
- bases, one of which may be the current polygon. You are asked whether you wish
- to expand the polygon parallel to the z axis (the default) or give
- a displacement in space. If you require the former, you are prompted for
- a single displacement value (height) along the z axis. If you wish to give
- a displacement in space, you are first asked whether you wish to expand the
- current polygon or a previously created one. You are then prompted for two
- points (from and to).
- The displacement of the new polygon from the original one is given by picking
- two points (from and to). This displacement is maintained between every point
- of the original polygon and the corresponding points on the new one. The
- direction of the edges connecting the two bases is determined by the direction
- from the "from" point to the "to" point.
- If you wish to expand a polygon, other than the current one, you are asked to
- indicate it and confirm its selection. You are prompted to select additional
- polygons.
- Answering the Y/N prompt with `y' creates a positive prism; `n' creates
- a negative one.
- If you attempt to execute the command on an open polygon, a system warning
- appears:
- ! polygon is open, will fail \solid !
-
- Example: \p3d n y 10 10 0 15 15 10 y
-
- Result: The current polygon is copied at a displacement of 5 units, 5 units
- and 10 units in the x, y, and z directions respectively. The two bases of the
- solid prism generated will be the active polygon and its copy. The prism will
- be a positive one.
