DWG compatibility
I've done some simple drawings for a client who uses Autocad LT, but he claims they hang his machine.I sent purged and cleaned up versions... same problem.I've just sent a few more versions, removed hatches, sent as R14, R12 etc. hoping he might open these.I don't have Acad here, so I tried Icad 2000. They all open, but all take a very long time and cause a lot of disk thrashing - I suspect he is seeing the same and assuming his computer has hung.Has anyone had similar problems and found any workarounds?

The only prob I had (before V6) was people not "seeing" xrefed dwgs, which I believe was a path issue. If it's a simple dwg there must be something strange in it, have you tried Wblocking or cutting and pasting into a new dwg? Or perhaps it's something like a font Acad does not have.I send a lot of files to Acad users and they never seem to have a problem, they are usually up to about 1.5Mb.

No Xrefs, nothing complex at all, in fact the whole drawing is only about 160k.Altered all fonts, tried exploding everything. No different.Cut and paste has made a difference, now loads immediately into Icad 2000 - and I thought I'd already tried that :\Thanks

Oh, something else odd happens when I save - I set Icad to save as R14 because it sometimes messes up the Mtext line spacing saved as R2000. So in a dwg which was originally saved as R2000, a popup which says something about R2000 entities appears each time unless I Saveas once. From then on it does not ask. Yours just might have something to do with how the "pastee" dwg was originally saved.

Hello Andy,if you attach the drawing to a support request we will investigate what is causing this trouble.Kind regards,Hans De BackerBricsCad Development

Thanks, drawing submitted with request.Interesting about the 'save as' version. Perhaps that's where the problem was created. Can't say I've noticed the popup warning here though, yet.

The drawing contains a hatch entity with handle 13BD which uses the ANSI33 pattern with scale 1 instead of 250 as for other similar hatches in this drawing. This results in a hatch with an extremely high number of pattern lines. BricsCad first checks the number of pattern lines to be expected and will not attempt to create display entities if the number of pattern lines is above the MAXHATCH value. Apparently AutoCad tries to allocate memory for the pattern lines till it grinds to a halt.The copy/paste trick worked because no display entity was created for the problem-hatch, so it did not get selected during the copy/paste to the new drawing.We will improve BricsCad to avoid that similar hatch entities can be created at all.Kind regards,Hans De Backer

That was quick, thanks.OK, I understand that. So there is no way of deleting it other than by its handle.I admit to having problems with remembering appropriate hatch scaling in my use of Bricscad so far, so that's probably where the error crept in.
