Why have solids started "bleeding"?

[Cadastrophic]

I have been using screen dumps of some solid models for illustrations, but yesterday, I zoomed in on one drawing and all the individual solids have very rough and mishapen edges and show other (coloured) solids "bleeding" through.
Also, when I used projection and set it to perspective all hell broke loose.
Have I done something wrong somewhere, or is this a hardware/software problem. I did try uninstalling and reinstalling ACAD2000 but to no avail. :(

By "screen dumps" do you mean screen captures? Instead of screen captures, use the "saveimg" command and save the image as a .bmp file. As for the "very rough and mishapen edges", try changing your "viewres" variable to a high number such as 1,500 and see if that helps.

Maybe a corrupt video driver. Type STATUS when it does not happen then when it does and see if their is an obvious difference.

Thanks for the replies. With regard to "saveimg", all that seems to produce is the wireframe image and not the shaded image which is what I'm after.
I have looked at a few other solids in another file, and they seem to be OK...perspective too. It's just that one drawing. Weird.
"Status" hasn't shown anything up so far, but I'll keep comparing.

What about PURGE ?

Are your solids completely separated? If two solids are overlapping you will get small rendering errors at the interference zone. Zooming in you can get those "small" errors covering the whole screen.
You can check the interference using the INTERFERE command.

fuccaro, you're absolutely correct! I had placed a small fillet on some edges before I "assembled" the whole thing. I obviously didn't place the individual solids accurately enough. I disassembled the entire object and reassembled it properly. Everything is now OK.
In future I'll leave the filleting to the very end.
