Exploding Filleted Curve

Have filleted some curves and then used them in a sweep, and though I can Deconstruct BREP, I cannot seem to break one of the resultant edges into straight and arc segments with Explode Curve, but can’t seem to do it: am I missing something here? How would you do this?


not able to explode a curve can have multiple reasons. However a curve composed out of a line segment and an arc segment is definitly a multispan NurbsCurve (a curve composed out of multiple Bezier curves). Now, since any curve is threaded as a NurbsCurve within GH, you can evaluate the knotvector to get the “span”-parameters, and split (shatter-component) at those parameters. The repetition of the numbers in the knot vector indicate the inner continuity those curves are connected to each other.
