PRIM_TYPE_TUBE

Description

Constant: integer PRIM_TYPE_TUBE = 5;

The integer constant PRIM_TYPE_TUBE has the value 5

PRIM_TYPE_TUBE is a parameter of PRIM_TYPE used to make prim into a tube and to change specific properties that define the shape of that tube.

PRIM_TYPE

[ PRIM_TYPE, PRIM_TYPE_TUBE, integer hole_shape, vector cut, float hollow, vector twist, vector hole_size, vector top_shear, vector advanced_cut, vector taper, float revolutions, float radius_offset, float skew ]

• integer	hole_shape	–	PRIM_HOLE_* flag
• vector	cut	–	x and y range from 0.0 to 1.0, x must be at least 0.05 smaller than y (z is ignored)
• float	hollow	–	ranges from 0.0 (solid) to 0.95 (maximum hollowed)
• vector	twist	–	ranges from -1.0 (-360 degree in the edit window) to 1.0 (+360 degree in the edit window) for both x and y (z is ignored)
• vector	hole_size	–	x ranges from 0.05 to 1.0; y ranges from 0.05 (large hole) to 0.50 (no hole)
• vector	top_shear	–	ranges from -0.5 to 0.5 for both x and y (z is ignored)
• vector	advanced_cut	–	x and y range from 0.0 to 1.0, x must be at least 0.05 smaller than y (z is ignored)
• vector	taper	–	ranges from -1.0 to 1.0 for both x and y (z is ignored)
• float	revolutions	–	ranges from 1.0 to 4.00
• float	radius_offset	–	depends on holesize.y and revolutions
• float	skew	–	ranges from -1.0 to 1.0

hole_shape Flags		Shape	hole_shape Flags		Shape
PRIM_HOLE_DEFAULT	0x00	Default	PRIM_HOLE_SQUARE	0x20	Square
PRIM_HOLE_CIRCLE	0x10	Circle	PRIM_HOLE_TRIANGLE	0x30	Triangle

PRIM_TYPE_LEGACY

[ 1, PRIM_TYPE_TUBE, vector cut, float hollow, float twist_end, float topshear_x ]

• vector	cut	–	x and y range from 0.0 to 1.0, x must be at least 0.05 smaller than y (z is ignored)
• float	hollow	–	ranges from 0.0 (solid) to 0.95 (maximum hollowed)
• float	twist_end	–	ranges from -0.5 (-180 degree in the edit window) to 0.5 (+180 degree in the edit window)
• float	topshear_x	–	ranges from 0.05 to 0.50

This is the old PRIM_TYPE format for the tube (PRIM_TYPE used to be 1 instead of 9). Use the new format unless you are maintaining old code.

It should be noted that topshear_x was intended to be hole_size_y and wasn't caught by QA; in the documentation it was listed by an equivalent term to hole_size_y. The bug became lava-flowed and was never fixed in the old incarnation of PRIM_TYPE.
