- Sections a solid entity on a plane, keeping both parts.
-
- 1. (CHAR) option: plane: (o-orthogonal, d-diagonal, f-free) <o>
- if option `o' is selected:
- 2. (CHAR) axis of section (x,y or z)
- 3. (CHAR) define the section by: v-value, p-point <p>
- if `p' is selected:
- 4. (POINT) point on section plane
- if `v' is selected:
- 4. (POINT) value on axis
- if option `d' is selected:
- 2. (POINT) first point on section plane
- 3. (POINT) second point on section plane
- 4. (POINT) pick point on first cut entity
- 5. (POINT) pick point on second cut entity
-
-
-
-
-
- if option `f' is selected:
- 2. (POINT) first point on section plane
- 3. (POINT) second point on section plane
- 4. (POINT) third point on section plane
- 5. (POINT) pick point on first cut entity
- 6. (POINT) pick point on second cut entity
- for all options:
- 7. * (IND) entity to be split
- 8. * (Y/N) confirm choice
- 9. * (Y/N) keep the result ?
-
- Description:
- This command sections a solid entity along a plane, keeping both parts of the
- entity.
- You have the option to section the entity in three ways:
- 1. orthogonally at a specified coordinate value (option `o', the default)
- 2. perpendicular to an axial plane (xy, xz, or yz, option `d')
- 3. by a free plane defined by three points (option `f').
-
-
-
-
- For option `o':
- Specify an axis along which the entity is to be sectioned. Then select either,
- `p' (default) to point to the position of the section, or `v' to state
- a coordinate value on the selected axis. The section plane will be normal to
- the axis at the specified value.
- For option `d':
- Pick two points on one of the axial planes (xy, yz or xz). The section will be
- cut through the two points perpendicular to the plane on which the points are
- located. Pick another two points, one on each side of the split plane.
- For option `f':
- Pick three points to define a free plane. Pick another two points, one on each
- side of the split plane. For all the points, indicate (and confirm) the entity
- to section. The two new parts of the original entity will be displayed
- temporarily. You are asked if you want to keep the result or not. Entering `y'
- causes the temporary entities to become permanent new entities. You are then
- prompted to indicate additional entities to be split until you enter a new
- command.
- The result of this process is a complex solid entity (data type 9). A wall
- sectioned using this command keeps the axis of a wall entity to enable some
- wall commands such as \oplac, \apsel, etc. Other wall commands (such as \chaw,
- \fixw, etc.) can no longer be applied. This command works only on walls and
- solids. You may not section lines, arcs, texts, or dimension lines.
- When indicating an entity to cut:
- 1. A wall entity must be indicated by pointing to its axial line.
- 2. A solid prism or any solid created by two polygons must be indicated by
- pointing to one of the edges connecting the polygons.
- 3. A complex solid (data type 9) may be indicated by pointing to any of its
- edges. You are prompted to indicate another entity to be split (by the same
- defined plane), until you enter the next command.
- If the split result is illegal, the following prompt will appear:
- result is not a solid; press <ENTER> and the original solid will be redrawn on
- the screen.
-
- Example: \split o z v 1 (indicate) y y
-
- Result: The indicated entity is sectioned along a plane normal to the z axis
- (parallel to the xy plane) at the point where z=1. Both parts are kept.
