I have tried removing copper, silkscreen, soldermask and solderpaste layers to see if these were causing the trouble, but have had no luck in finding out why Altium does this. Upon importing these step files into a 3D CAD program, more often than not you will find that some of the holes have been covered (or partially covered) up by a very thin solid on the top and/or bottom. UPDATE, March 2016: This does not seem to be happening anymore with AD15 or AD15.Īltium decides whether or not it wants to export holes/vias in step files. In my experience, this causes Altium to crash with the infamous “Please Wait A Moment…” message. You can put images into Altium schematics, but don’t do it via the copy-paste way from a program that has an unsaved image (like Snip). Here a some of the things you should keep an eye out for…Īltium will make arcs disappear on certain zoom levels if the arc is almost fully circular. If you are getting annoyed with one of Altium’s bugs, submit it to BugCrunch, their bug tracking and fixing sub-site (you can vote on what you want fixed first). There’s no denying Altium has it’s quirks.
