How to measure the outer side of an arced solid?

Rhino
1

Two-fold question:

  1. How can I fillet the edge of the block to match the outer side/edge of the curved solid? The curved solid is an arc.
  2. I thought I could measure the radius of the outer edge, using a radius dimension, and then fillet the edge to that radius value. But I can not figure out how to select that outer radius

Hi Grant -

If those are tangent surfaces, running DivideAlongCreases with SplitAtTangents=Yes will give you edges that you can use for radius input.

Another possibility is to use ExtractIsocurve to obtain a curve which can be used as input to measure the radius.

Hi @Grant837
Also, you can just use the Radius command and select one of the outer edges to get the number in the command prompt - and you can then copy/paste if from there :slight_smile:
