- SURF Menu: (POLYG) PEDIT
- ==============================================================================
- Creates a set of surface polygons along a predefined plane or a free plane.
-
- 1. (CHAR) create surface along: (x, y or z) <z>, f- free point
- if `x' or 'y' is selected:
- 2. (NUM) width of surface (other than 0)
- if `z' is selected:
- 2. (NUM) height of surface (other than 0)
- 3. (POINT) first point
- 4. * (POINT) next point (for arced surfaces press <ENTER>)
- if you press <ENTER> for arced surfaces:
- 5. (POINT) second point of arc
- 6. (POINT) last point of arc (<ENTER> for a NEW second pt.)
- if `f' is selected:
- 2. * (POINT) first point
- 3. * (POINT) second point
- 4. * (POINT) through point

- Description:
- This command creates a model of closed surface polygons. It works like the
- \line command, but, instead of creating a line, it creates a rectangle surface
- polygon. You may also create an arc of surface polygons defined using three
- points; the system will create seven surface polygons. Another possibility is
- to define a free plane, by three points.
- You are prompted to select a creation option: along one of the major planes
- `x', `y' or `z' (`z' is the default), or define a free plane (option `f'). If
- `x' or `y' is selected, define the width of your surface polygon (you may
- enter a negative number to create the surface polygon in -x or -y, you may not
- enter 0). If `z' is selected, define the height of your surface polygon. Then
- define the first point of the polygon and when selecting the next point, the
- system creates a rectangled surface polygon with the defined width or height,
- allowing you to continue. Note that you may press <ENTER> to define a set of
- arced surface polygons by second and last points.
- After creating the arc, or any other linear surface, the system returns to
- parameter 4, "next point", until you select a new command.
- If you select option `f', the system asks for a first point, second point and
- a through point. The surface is created using the three defined points as the
- borders of the surface polygon.
- This command is especially useful for creating a quick economic "card" model
- that may be presented in hidden lines removal in the solid module.
