If you are referencing an existing 2D drawing, check the drawing you are going to use for your profiles

You can reuse 2d drawings to create any profile or feature in your 3D model. They can be both created from the think3 application and imported via DXF, DWG or IGES. Before doing that, check the geometry you are going to use:

• Use the Chain command and/or the X-Hatch command to check the 2d entities for gaps, overlapped curves and so on.
   
• Delete all unwanted and unnecessary entities (for instance, two aligned consecutive lines that should be represented by a single line).

  

Some DWG or DXF drawings may "propagate their tolerance problems". If you are inclined to retrieve just the information on the geometry, a way to 'heal' them, without dealing with tolerances, is to save the drawings in the program's internal format (the think3 application Neutral Format, .gkd) and then import the geometry into your model (using the Insert From File command, or just drag and drop).
