<div>Dear All,</div>
<div>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.</div>
<div>I copy the IGES below.</div>
<div>Do you have any idea why Coherence does not work in this case?</div>
<div>Thanks</div>
