spiral pitch

The Spiral under Basic Shapes should have "Pitch" listed under Structural Settings. Fabricators always ask for this, the angle to horizontal if you were to "unwrap" the spiral from its defining cylinder.

I assume you mean at the centerline since the pitch will vary from inside to outside.

Hmm, maybe I should start with a request that the object called "Spiral" be renamed "Helix". What I'm calling Pitch should be constant along a helix, at least a regular one, like the handrail of a, (ahem) "spiral" stair.

Basic Shapes could include conical spirals, planar spirals, Archimedean spirals, etc., (which would have varying pitch if I understand you) but that's not part of this wish.
