Why my dwg file doesn’t show up after imported to InteriCAD Lite?

Why my dwg file doesn’t show up after imported to InteriCAD Lite?

Answer:
There are a few reasons that could cause this problem:
1. The color of the objects in the drawing is white, so it’s difficult to recognize with
the gray background;
2. 2D Design cannot support object in solid type, it will be filtered during importing;
3. The objects in the drawing are far away from the original point.
User can modify the dwg file according to the reasons above if this problem happens.
