Create Section Wizard cant use Arc Element

Dear Forum


Descartes v8i ss5

When using the Create Section Wizard in Point Cloud Presentation, id like to be able to use an Arc Element but it wont allow me. I can use a Complex Chain and a B-Spline [oddly enough] but not an Arc. Is this how this tool should work?

Oddly id have thought a B-Spline was a more complex line to use???
