Low quality in geometry when opening 3D dwg file from C3D

Issue:

When watching an Autodesk® AutoCAD® Civil 3D® 3D DWG in the A360 Online Viewer the geometry of 3D solids appear degraded and of low quality.

Causes:

The A360 Viewer is not (yet) designed to work with Coordinate Systems. 
If the 3D solid geometry is very for from the origin (X,Y = 0,0) the geometry display gets degraded.

Solution:

• Before uploading a georeferenced DWG to the A360 Viewer, move all objects as close as possible to X,Y = 0,0
