World Based unit scaling

[Razzman]

I'm having a symbol scaling issue. I receive DWG files from my factories with items to drop into a floorplan. Everyone uses AutoCAD. I typically, Import these into VW and take the view I need and Create Symbol and keep these in a file with represents that particular manufacturer.

When I go back to my floor plan which might be in 1/4" scale, I would go to my resource browser and bring in that symbol which would be rescaled to that layer. Recently, on some of these (not all) symbols I've created, they don't rescale. They are giant. Not a real dealbreaker, because I'll go to Scale Objects (if I remembered the original actual dimension) and this works. The other day, even this didn't work and the symbol remained as a giant.

I notice that up in the Obj Info box, these items are listed as "World Units"

Is there a way when creating these and or using these symbols that they just rescale automatically?
