Hi all,

here is a very simple workflow for all those who what to modify their featureEdgeMesh for snapping. Sometimes it happens that the *.eMesh which is generated by surfaceFeatureExtract is not very nice. Then you have to check and test and repeat it till you know, the result you want is not reachable or its done after a few runs. If you are familiar with that tool, the triangulation of STL's its very easy to produce good featureEdges with surfaceFeatureExtract. But if you want to generate your own one in a very simple way using blender, you have to do the following:

• Load your STL

• Switch to editing mode

• Select all with [a]

• Press [w] and "Remove doubles"

• Go back to object mode

• Use edge-split-modifier and accept it

• Select -> Boundary Loop

• Press [p] -> Selection

• Remove the STL from your blender session

• (maybe rotate the feature edges 90° on the x-axis)

• Export the featureEdges as *.obj

• Take a look at it with paraview and compare to the stl

• Convert *.obj to *.eMesh

• Done

The nice thing is, that you can add, remove or modify edges and vertexes as you want and modify it like you wish.

Have Fun
