You can select either a Planar, Spherical, Cylindrical, or Conical surface. For surface type, select the type of surface you want to create.Clear Dynamic Help if you do not want to display detailed help.Go to Insert > Surface > Surface From Mesh.To Create surfaces from meshed faces, take these steps: Imported *.stl file in SOLIDWORKS is meshed/tessellated. Go to Tools > Options > Import, and under File Format, select STL/OBJ/OFF/PLY/PLY2 and click Import as Graphics Body. Now if you open a *.stl file, you will see the file look like the below image: To import tessellated models into SOLIDWORKS, we need to setup the opening format. Because the feature only creates surfaces, the recommended workflow is to trim the surfaces to form The tool may not be appropriate for highly irregular meshes such as those created from a 3D scan of an organic shape.


The Surface From Mesh tool works best on mesh files with regular prismatic geometry such as planes, cylinders, cones, and spheres. In SOLIDWORKS 2017 a *.stl file could be converted into solid body, however, it will still be tessellated. New in SOLIDWORKS 2018 is the Surface From Mesh tool, it lets you manipulate a mesh object that you imported from an *.stl, *.obj, *.off, *.ply, *.ply2 or *.3MF file to create surfaces and solids. Round faces will have more segments than flat faces.

All faces are broken into some triangular faces. When a *.stl or *.obj file is imported into SOLIDWORKS, the 3D model opens in a tessellated or meshed form.
