- QTCYL Menu: PRISM
- ==============================================================================
- Creates a quarter-circle polygon or a solid quarter-circle prism
- (quarter-cylinder).
-
- 1. * (CHAR) plane of base quarter circle (x-xy, y-yz,z-zx) <x>
- 2. * (POINT) center point
- 3. * (NUM) radius (greater than 0)
- for option `x':
- 4. * (NUM) height of prism
- for option `y' or `z':
- 4. * (NUM) length of prism
- for all options:
- 5. * (Y/N) positive prism? <y>
- Description:
- This command creates a quarter-circle polygon or a quarter-circle prism based
- on that polygon (quarter-cylinder).
- Specify the base plane (one of the axial planes; x xy plane the default, y
- yz plane or z xz plane), the center point, radius and height (for option
- `x') or the width (for options `y' or `z'). You may enter `0' for a 2D
- polygon. Specify whether the solid is to be positive (option `y', the default)
- or negative (option `n').
- You are prompted to create additional quarter-cylinders until another command
- is selected.
-
- Example: \hfcyl x 3 3 0 4 1 y
-
- Result: A quarter-cylinder is created with its center point at 3 3 0,
- a radius of 4 units (meters or feet), and a height of 1 unit.
