I have a .stl file I did some months ago and I wanted to open it on solid edge. When I selected the file, another window appears where I can select the extention and then a message shows "the stl file have only facet data. The facet data can only be imported in ordered environment" (I translated the message because my solid is in spanish).
Solved! Go to Solution.
I did open the file with the recomendation you give, but now I have another problem... I cannot modify the figure!
The STL file is a tessellated file, in that, it's a view only entity.....you'll need to use another neutral file format, such as STEP, IGES, or Parasolid,...in order to get editable 3D geometry into Solid Edge.....or place the STL part in an assembly template, then use "Create Part In-Place" to build a replica of the file, while being able to see the shape of the STL during model creation.
