- HFCYL Menu: PRISM
- ==============================================================================
- Creates a semi-circular prism (half cylinder) or a semi-circular polygon.
-
- 1. * (CHAR) plane of base semi-circle (x-xy,y-yz, z-zx) <x>
- 2. * (NUM) option: (0-top half /3-right half /6-bottom half /9-left
- half) <0>
- 3. * (POINT) diameter starting point
- 4. * (NUM) diameter (greater than 0)
- for option `x':
- 5. * (NUM) height of prism
- for option `y' or `z':
- 5. * (NUM) length of prism
- for all options:
- 6. * (Y/N) positive prism? <y>
-
- Description:
- This command creates a semi-circular (2D) polygon or a semi-circular prism
- based on that polygon. Specify the base plane (one of the axial planes; x xy
- plane [the default], y yz plane or z xz plane). Choose one of the options
- for the semi-circle orientation: 0 top half, 3 left half, 6 bottom half, or
- 9 right half (the default is 0)
- Define the starting point and diameter. Give a 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 half-cylinders until another command is
- selected.
-
- Example: \hfcyl x 0 3 3 0 4 1 y
-
- Result: A half-cylinder is created with its diameter starting point at 3 3 0,
- a diameter of 4 units (meters or feet), and a height of 1 unit.
