Exploding DWG Files

 “Just don’t explode DWG files” is good advice, that is immediately ignored because…reasons

Setting that aside, now that we’ve exploded that DWG, now what. First, there is full explode versus partial explode. A full explode will recreate all the DWG elements into native Revit elements (assuming it is possible) but a partial explode will produce some native elements and some new DWG elements (blocks).

Reducing all DWG elements to equivalent elements in Revit is fraught with peril. Not all blocks in a DWG are created well. Explode one block that happens to have very large extents and your project will now have display/graphics issues. A Revit project might have one imported DWG but many times that number after partial exploding.

I recently encountered three project files that had +95k imported DWG files. These were the result of partial exploding less than 20 DWG files. As most…
