- Queries the type of polygon and converts the polygon from one type to another.
-
- 1. (CHAR) option: t-check type, l-check loops, p-no. of points
- 2. * (IND) polygon to query
- 3. * (Y/N) confirm choice
- if option `t' is selected:
- if the polygon is a symbol polygon:
- 4. (Y/N) polygon is a SYMBOL polygon, change to SURFACE ?
- if the polygon is a surface polygon:
- 4. (Y/N) polygon is a SURFACE polygon, change to SYMBOL ?
- if polygon was at any time part of a prism:
- 4. ! this polygon is or was PART OF A PRISM, unchangeable !
- if option `l' is selected:
- if polygon is closed:
- 4. ! all loops of the polygon are CLOSED
- if polygon has open loops:
- 4. (Y/N) last polygon loop is open, wish to close last ? <y>
- if inner polygon has open loop:
- 4. ! polygon has open inner loops !
-
- if option `p' is selected:
- ?? No. of polygon points: NNN (press: <ENTER> )
- where NNN is the number of points in the polygon.
-
- Description:
- This command queries the type of polygon and converts the polygon from one
- type to another (option `t'), checks whether the polygon has open loops
- (option `l'), and queries the number of points in it (option `p').
- Option `t'A polygon, during its creation, appears as a transparent wire
- (symbol) entity in the solid module, until it is closed. It then appears as
- an opaque surface polygon. This option enables you to query the current status
- of the polygon and convert it from one to another.
- Indicate the polygon. The system tells you the polygon's current type and asks
- you if you wish to convert it.
- You cannot use this command on polygons that are or were part of a prism. If
- you attempt to do so, the following message will appear:
- ! this polygon is/or was a PART OF A PRISM, unchangeable!
- Option `l' Checks whether a polygon is closed or open, and enables you to
- close it if it is open. Only a closed polygon may be used as a surface polygon
- in the solid module or be used to generate a solid body.
- Indicate the polygon. The system will tell you if it is closed or open. If it
- is open the system will ask you if you wish to close it.
- Option `p'This option queries the number of points in an indicated polygon.
- The maximum number of points allowed in one polygon is 200.
- Indicate (and confirm) the polygon you want to query.
- In all options, the polygon operated on becomes the current polygon.
- If the entity indicated is not a polygon the following message appears:
- ! entity is not a polygon
