And would you just look at that. It fixed all my other problems!
For anyone else out there. If you run to this issue with the Region Difference throwing a “1. Solution exception:Object reference not set to an instance of an object.”
I inserted the “original plane for boolean solution” (obvious) then Graft it and it fixed the issue.
Christopher,
How exactly do you do this? [quote=“christopher.ho, post:4, topic:96584”]
I used the centre of the circle as an attractor point to sort out the direction of the slit before taking the front or back.

The intersection between brep | brep is a curve that has no specific orientation.
By taking the end points of that curve and reordering them by distance towards the centre of the circle
I can create a straight line where they are all lined up in the same orientation.

Perfect! It worked.
Thanks again!
