- Sections a selected group of solid entities on a plane.

- 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)

- if option `p' is selected:
- 4. * (POINT) point on section plane
- if option `v' is selected:
- 4. * (POINT) value on axis
- 5. (POINT) specify location within part to be kept
- if option `d' is selected:
- 2. * (POINT) first point on section plane
- 3. * (POINT) second point on section plane
- 4. * (POINT) pick point on part to be kept
- 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 part to be kept

- Description:
- This command sections all selected solid entities along a plane:
- 1. orthogonally at a specified coordinate value (option `o', the default), or
- 2. perpendicular to an axial plane (xy, xz, or yz) (option `d'), or
- 3. by a free plane defined by three points (option `f').
- For option o:
- Specify an axis and select one of two further options: `p' - to point to the
- position of the section (the default) or `v' - state a coordinate value on
- the axis selected. The section plane will be normal to the axis at the
- specified value. Then enter another coordinate value on the same axis to
- indicate which side of the section plane is to be kept.
- 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 point to indicate the side of the section that is to be
- retained.
- For option `f':
- Pick three points to define a free plane and a fourth point to indicate the
- side to be kept.
- The sectioned entities will be displayed temporarily. You are then prompted to
- keep or regret the result. Entering `y' causes the temporary entities to
- become permanent.
- The result of this process is a group of complex solid entities (data type 9).
- A wall sectioned by this command becomes a complex wall and continues to
- posses the characteristics of a wall but the commands \chaw, \chaa, \fixw, and
- \fixa have no effect. This command sections only walls and solids. You may not
- cut lines, arcs, texts, or dimension lines.
-
- Example: \sects o z v 1 0 y
-
- Result: The selected entities are sectioned along a plane normal to the z
- axis (parallel to the xy plane) at the point where z=1. The parts having a z
- value larger than1 disappears, leaving only the parts where z is less than 1.
