I'm using Structure 2018 and am having a problem with the 2DREPSTR command. When running the command on a viewport only the centerlines will show up with no line work for the steel. This happens on actual models or xrefs. The models are located in plant space so coordinates like x 170000 y 110000 z 100000. When the models or xrefs are moved closer to 0,0,0 the command works perfectly through the viewport.

Also, when running the same command in model space, the 2D line work/block is created but scaled and moved towards the 0,0,0 coordinate. Centerlines show up correct and in the correct spot but line work for the steel is what is scaled and created in the incorrect position. Shows up really small. Once again when the model or xref is moved close to 0,0,0 command works perfectly creating the 2d block with centerlines on top of the steel objects.

I'm at a loss as to a setting that in AutoCAD 2017 or Cadworx that might be causing this. Anyone ever seen this before?
