Hi all, I’m still encountering a lot of issues exporting (vector) pdfs from a layout using technical view. This has been an issue for a while now (see here or here ). Sometimes curves “show through,” but more commonly for me, curves are missing. In a highly complex design, it’s not feasible to go i…

Hi Sam - [image] sam: Here’s one example, but I run into it all the time: […] [image] sam: I can’t upload the model for confidentiality reasons […] We can’t troubleshoot issues like this from images. Since you are running into this all the time, hopefully one of those cases occurs in…

Hi Sam - [image] sam: Also if it helps, here’s the custom display mode – maybe this all boils down to me missing a checkbox somewhere. Let me know if it’s that simple :grimacing: Yes, you didn’t check the intersections option… [image] As for the extra lines that are getting drawn, this is…
