Add Dimension to STL File

How can I add dimensions/measure an STL files in solid edge?


  • Open the STL file in Solid Edge and then create precise profile sketch geometry.  
  • Think of the STL data as an image and sketching over it with lines/arcs/circles.  
  • Then measure those. 

Note: this is not precise as the stl data is faceted information and not precise. It is used more for visualization.


Example, create a 4x4 block with a 2" diameter hole in it.  Export to STL and reimported.  Created a sketch with lines and circles and the resultant dimensions were within 2% of the actual values.
