Hello Friends,

I've had a successful iteration of this part which is a study to try and estimate how a coil of cable will drape or hang in my project. But, by trying to alter it to more accurately follow my real world sample, I have stumbled on a strange phenomenon.

As you can see below, I have twisted a surface along a spline to create a coiled path to sweep along (Thank you for helix-helix @Paul Salvador)... At one of my lower control points where the curvature of the spline has brought the loops into a possible interference, the sweep has jumped a revolution of the path! What strange magic is this?

This is not super critical with respect to my model but I did want to get rough idea of where to place the holster for the IEC plug and the upshot would be a nice model for our marketing team to use in the full product renderings. The attached model is unfinished and configured to be Draped, Hung and As Drawn, where i will ultimately lay it flat and straight to describe it to our suppliers.

Before I set off in that direction, could you offer some constructive comments on this approach and maybe I could simplify the method? (hoping for an avalanche )

Warm regards, Bob

Hello Bob,.. yeah, it's intersecting so reducing the diameter works or changing the original center sweep path/loop can help..

but... as is, if you want make it work, use Profile Twist - "Natural" (seems to allow for intersection).. (image attached)

..and... "Tangent to Adjacent Faces" also will allow the intersection in this case..

..and furthermore,.. if I relax/reset the center curve (34 and 38 differences).. there are new overlapping/intersecting issues on the v1 and v2.. so, the center curve needs to be massaged to work cleanly for both.

..lastly,.. I'll add an example of making this more consistent.... create a Arc Chain (master/parent) for the drape,.. and then Convert the arc chain into a Spline (child). (this is the way of the sweep/twist beast.. it's more consistent or likes doing it this way).
