[Gmsh] Fwd: iges coherence

[Miklós Ecseri]

Dear All,
I imported an IGES to GMSH. As there are many coincident points, I try to
use the Coherence but then all points and lines are deleted. Tolerance is at
default: 1e-006.
I copy the IGES below.
Do you have any idea why Coherence does not work in this case?
Thanks
Miki
