I am in the midst of making framing for a geodesic dome. Basically I did a wireframe version then offsetcrvonsrf to create a 50mm wide framework. Upon joining the ends of a section of frame to extrude and organise into joins at the meeting points it says the rectangles are not planar.
I can get the short sides of the rectangle (pictured) to be perpendicular with the long sides, however, this will change the angles of the dome and I won’t be able to accurately model the framework. So I want to extrude the original rectangles along a curve that is vertically perpendicular (second picture) to the short side but don’t know how to position my cursor to do so without it thinking it is in a completely different location. Are there any commands for this like setting a snap point to the end of the short curve and placing my cursor somewhere?
