Topic Title

I just tried that and get the same results. If I do a page up to the largest defined scale I see a spot and if I Identify from various angles it I get a line at o" length or an arc of 0" radius.

This help in the diagnosis?

More than likely there's an entity from Acad (a stray part from an exploded symbol, a point, etc.) that is the offending "nasty". If you select this and delete it, does it affect anything?

No, that doesn't work either.

All of the entries are (I think) lines and arcs of no measurable length or no measurable radius. Doing an 'extents' brings up "invalid zoom windoe defined" even though there are hundreds of entities.

Can I assume that the DXF file is bad?

Thanks

The files are H Window details of jambs, mullions, etc. Don't think there are any contour lines or such.

Oh, well. . .

Try changing the import units. Maybe they set it up with a unit of 1/32" instead of a foot (?).
