pytha.create_tube

Creates a tube (hollow cylinder) in PYTHA as new part.

Similar to the Parts -> Tube function in the PYTHA user interface.

pytha.create_tube(height, outer_radius, inner_radius [,origin [,options]])

Parameter	Type	Description
height	number	Height of the tube (in w/z-direction)
outer_radius	number	Outer radius
inner_radius	number	Inner radius (bore). Must be smaller than outer_radius; if the two are equal a thin wall is used automatically.
origin	{x,y,z}	Optional: center point of the base
options	{...}	Optional: a table that may contain the following options:
options.u_axis	{x,y,z}	Local coordinate u-axis for the orientation of the tube
options.v_axis	{x,y,z}	Local coordinate v-axis for the orientation of the tube
options.w_axis	{x,y,z}	Local coordinate w-axis for the orientation of the tube
options.segments	number	Circle segments of the tube
options.height_segments	number	Height sections of the tube
options.top_outer_radius	number	Outer radius at the top. Defaults to outer_radius (a straight tube); a different value produces a tapered (conical) tube.
options.top_inner_radius	number	Inner radius at the top. Defaults to inner_radius.

Additional information

By default the tube is straight (top radii equal the bottom radii). Specify options.top_outer_radius and/or options.top_inner_radius to taper the tube — the radii are interpolated linearly from bottom to top over the height sections.

Return value

Type	Description
element_handle	An element handle of the newly created part
