geo/M2DRevolve

Spins a flat 2D profile around the Y axis into a solid.

Manifold Operations

Takes a cross section as a lathe profile and turns it about Y, giving a 3D manifold. The profile is the shape's own area, so the part of it at x = 0 sits on the axis and the part further out sweeps the wider ring. A profile that crosses to negative x is not what this reads.

The input is brought into world space first, so upstream transforms are honoured, and the result is a 3D manifold that geo/M3DBoolean and geo/ManifoldDisplay take from here.

At less than a full turn the solid is capped on both cut faces, so a 90 degree revolve of a rectangle is a quarter of a tube with two flat ends rather than an open shell.

geo/M2DExtrude is the other way to make a solid out of the same cross section.

Parameters

Name Type What it does
segments UInt32 How many facets a full turn is drawn with. Raise it for a smooth round surface, lower it deliberately for a faceted one.
angle Float How far round the profile is swept, in degrees. 360 closes the solid; anything less leaves two cut faces, which are capped.
