Importing AutoCAD 3D Model Face Issues

Hi,

I am having some issues when importing a 3d Model from AutoCAD into sketchup Pro 2016. It appears that there is a visualization problem with faces, as it is shown in the image below.

The 3d Model was imported in the Origin (0,0,0) and the Merge Coplanar Faces and Orient Faces Consistently boxes were checked too.

The only way i managed to fix it, is by exploding the groups and re-creating them again. However it takes a very long time to do this job.

I would appreciate if anyone could help.
