Why my CAD drawing is imported into Drawing Manager but the CAD drawing does not show up?
CAD drawing fail to import could be caused by CAD drawing format and CAD drawing file size.
It is recommended to use AutoCAD drawing 2010 format. Enormous CAD drawing should be split
into different CAD drawing files to reduce each file size and also to avoid the import failure.
I have imported drawing successfully but why some part of the CAD drawing is missing?
This can be caused by the external reference used by drawing author in CAD drawing. CAD
drawing with external reference will lose data once it is being copied without the external
reference data. The use of external reference can reduce the CAD drawing file size but it will not
be compatible with BIM based software.
