- Projects or projects and copies a polygon onto a plane.
-
- 1. (Y/N) option: y-project, n-project & copy <y>
- 2. (CHAR) projection axis (x,y, or z)
- 3. (POINT) first point of plane
- 4. (POINT) second point of plane (<ENTER> for a NEW first pt.)
- 5. (POINT) third point of plane (<ENTER> for a NEW second pt.)
- if option `y' is selected:
- 6. * (IND) polygon to project
- if option `n' is selected:
- 6. * (IND) polygon to project & copy
- 7. * (Y/N) confirm choice
- 8. * (Y/N) keep the result ?

- Description:
- This command projects, or projects and copies a polygon onto a specified
- plane. The projection is in a direction parallel to the x, y, or z axis. If
- you decide to project only, the original polygon will be projected to its new
- position.
- Select whether you want to project only, or project and copy.
- Enter the axis of projection (x, y, or z). Pick three points to define the
- plane onto which the polygon is to be projected. Indicate and confirm the
- polygon to be projected, or projected and copied.
- If the projected polygon is part of a simple solid, the resulting solid is
- modified accordingly, but will only be updated on the screen after a redraw.
- 2D polygons containing arcs will be projected, while each of the arcs will be
- changed to seven line segments. The command may not be executed on a polygon
- of a simple (prism) solid that includes an arc.
- Once the change has been executed on screen, you are asked if you wish to keep
- the result. If you reply `n', the operation is undone.
- You are prompted for additional polygons to project until you enter a new
- command.
- NOTE:
- Polygons which are part of a complex solid are projected and copied, not
- projected only. 2D multi-layer walls and openings cannot be projected.
- Polygons which are part of multi-layer walls, openings, or axial walls are
- projected along the Z axis only, but copied along all axes.
-
- Example: \proj y z 0 0 0 1 0 1 1 1 1 (indicate) y
-
- Result: The indicated polygon is projected in the z axis direction onto
- a plane defined by the three points 000, 101, and 111.
