Block problems with dgn to dwg conversions

[dpresley58437170]

I'm getting dgn files from the subs of a project I'm working on. When I convert them to dwg format, they contain a large number of AnonymousCell block references.

These are numbered consecutively, so "select similar" doesn't help when trying to operate on them. As an example, I have blocks named "AnonymousCell418", "AnonymouseCell419", etc.

At what point (or, on who's end) in the conversion is this happening?

Even when a block has a name, it has a number appended to it. For instance, a manhole block might be named "MH", and then "MH1" through "MH-whatever.."

Any ideas? Thanks in advance.

uStn uses what they call 'cells', not blocks, Not quite the same thing, and every instantiation of a cell can be modified after the insertion, but it's still considered a cell. Since Acad has nothing that works that way, the only solution they could come up with was to treat every cell instance as a unique block definition, keeping the cell name, and appending a numerical identifier.

Maybe look for a "BlockMerge" routine, but be aware that MH1 may be slightly different from MH87 - if the uStn persons changed anything after placing the cell.
