Hello,
I am having a problem using the API to sweep a profile along a path without a guideline which does not through any errors using the GUI.
This script will eventually be moved to my Add-In and is supposed to take a 2D profile, angle it to match the pitch of a staircase and sweep the profile along the path to create a returned mitered handrail. I've attached a picture of me using the GUI to make the final sweep.
I've been getting errors but I cannot determine why. I've already spent a good amount of time playing around with the script over the course of a few days and don't seem to be getting very far.
The troublesome part of this script begins on line 100.
Also: this script uses a 2d.dxf file which is a very important part of the final outcome (where the user should be able to select from a list of GUI-created profiles. So I've attached the script folder with that file.
