Error: Conversion error for: Body1 T-spline surface partition failed [defect]

[npcozyy]

My design keeps saying that the Error: Conversion error for Body1
T-spline surface partition failed [defect], but it doesn't show the highlight portion of the freeform as regards the stated problem.

1. Is it possible to indicate the error message above without clearly highlighting the areas that are the cause of the problem

2. How do I mitigate this particular problem. I do not see clear reasons as to why I cannot exit the form workspace

Please share your model. Export as .f3d and attach to post.

Done

I am not sure what exactly the problem is as your mesh is. However, it has a large number of n-gons and I would fix that first and also make sure I model 80% in box view mode.

Alright. Thanks.
