I have a solidworks model which I exported as an STL file. Then I used the

Geometry.Tolerance = 1.e-12;
MeshSize = 0.1 ;
Merge "refined.stl" ;

Point(2) = { 1.4,-1.0,-1.2, MeshSize};
Point(3) = { 1.4, 1.4,-1.2, MeshSize};

Surface Loop(2) = { 2, 13, 17, 21, 25, 26};
Volume(2) = {2,1};

When i do
gmsh -3 test.geo
I get the following error
Error: Invalid PLC.
Hint: Use -d switch to check it.
Error : Self intersecting surface mesh, computing intersections (this could
take a while)
Constructing Delaunay tetrahedralization.
Creating initial tetrahedralization.
Incrementally inserting points.
I see that I have intersecting facets but is there any thing i can do to fix
it? (either a switch in gmsh or something i
should do in solidworks)
Hi,
you should modify your model in solidworks so that you don't have intersecting
surfaces...

Dave
