Hi Stewart. This is a new one to me. I wonder if it is pcb or library related. If you create a new project with a blank PCB and use these library parts do you still get the error?
Thanks for testing, interesting result. I would be more than happy to try and reproduce here if you would be willing to email through the library file with the DIP8 part. If I can reproduce then I can arrange for a ticket to be raised with Altium.
If you can provide or PM me your email I will send thought my library. So far it's happened with DIP8 as demo'd, TH resistors, TH capacitors and other square box components...
I'm also working on it on another computer. I just now lost some lines when I used "Import Changes From..." changing a few SMD footprints to TH. I guess it seems to happen when a footprint is being replace or updated?
I've been trialing CS for a few weeks now - I have a bug I can't seem to find anyone else mention.
When I update a footprint in my PcbLib and push it to my PCB ("Update PCB with xxxx") the vertical or horizontal overlay lines may disappear. It's not just a rendering problem as the lines are not present in 3D view or on the Gerber outputs either.
PCB Library footprint
How it appears on the PCB - note the lack of horizontal lines on the DIP8 component and also the lack of vertical lines on C1 also caused by the same bug.
This is effecting a lot of my components, but not all of them. E.g. C1 (pictured) is bad, but most of the other capacitors using the same footprint are OK.
Please advice if there is a workaround or bug fix planned or if you need further details.
