I am trying to use the Draft Angle Analysis tool in order to create a parting line of a SubD object for mold making, however, sometimes the draft curve that is generated is not continuous and has a lot of gaps. How do people get a perfect continuous curve around the model using this tool? Additionally, I have seen videos where the Draft Angle Analysis tool could be adjusted to fit a model better (avoiding undercuts), but I do not know how that is done. Any advice will help. Thanks.

I am facing the same issue here with the subD model wont generate a parting line through the draft analysis. Is this only possible with solid models?
I’ve just sent an email to tech@mcneel.com and shared the model for your review.
I wanted to share this with the community, as others might encounter a similar issue.
I’m working with a complex physical form model (head). After converting from mesh to SubD and executing the ‘DraftAngleAnalysis’ command to create a mid Draft curve, I’m not getting any result, regardless of the processing time. I suspect it might be due to the extensive number of faces, but being a novice, this is just an assumption.
Here’s the process I followed to achieve a seamless parting line. Please note that these are my initial steps in Rhino, and there may be more efficient methods:
I translated the object into a solid. Despite repeating the process, it generated a parting line quickly, but tweaking the options didn’t yield a continuous parting line.
I discovered that I could join it using the ‘Join’ command, creating a uniform curve.
I then rebuilt the parting line, resulting in a nice continuous parting line on a solid object.
Feel free to check the model, and any insights would be greatly appreciated. Thanks!
