Imported AutoCAD layout disappears when I zoom in

[ FlexSim 18.1.1 ]

I have successfully imported a layout from AutoCAD and properly scaled and positioned it. However, when I zoom in to the layout it disappears from view. I don't think this is the OpenGL issue as the layout is visible when I pull back. I understand that FlexSim reduces detail when you zoom out, but this is the opposite problem.

The object scale factors affect the view culling of the DWG renderer.

If you change your background object so that it is scaled uniformly (change the X, Y, and Z sizes to all be the same value), then the drawing should stop clipping inappropriately when you rotate or zoom the view.

If you need non-uniform scaling, rescale the drawing in AutoCAD.

Absolutely correct! That should really be in the documentation. I entered a uniform scaling value for X and Y but not Z because, it's a 2D drawing so why would the Z matter? I get it though from a rendering / camera perspective. Thank you!

I'll add a note to the dev list to put this in the documentation. Thanks.
