The curve where the surfaces of two Solids meet, traced numerically. It is a Curve with no volume, useful as a rail or spine for a transition surface such as the conic sweeps.
The first Solid.
The second Solid.
Optional. Two Solids often meet in more than one loop (a tube passing through a wall has an entry and an exit); the loop nearest this point is traced. Unwired, whichever loop the search finds first.
Step length, from a wire; replaces the typed value.
Offset from Solid a, from a wire; replaces the typed value.
Offset from Solid b, from a wire; replaces the typed value.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
Where the curve begins.
Where the curve ends.
The curve's unit direction at its start.
The curve's unit direction at its end.
Unit vector along the straight chord from start to end.
Length measured along the curve.
The center of the curve's bounding box.
The axis-aligned extent of the curve.
Distance to the curve as a field, zero on the curve; give it volume with Thicken Surface.
At each point, how far along the curve its nearest curve point lies (computed on the CPU only).
True when the curve's end meets its start.
The display name of the node that made the curve.
The same curve, running from end to start.
