Geometry Editing Tool - Extend : How to stop edges imprinting onto faces

(OP)

24 Feb 24 09:14

When I extend an edge to a solid or surface, FEMAP automatically imprints a new line on the solid/surface (surface 1 in the below) . This is ok, until I extend an adjacent edge to another surface (surface 2 in the below) . The original remains, which can lead to sliver type elements when meshed. I can fix it by removing the line, but seems a bit of a faff, especially when there are a lot of edges to extend. Is there a way of switching off the imprint function

?

I can use mid-surface intersect when the geometry is ready for imprinting edges etc.

Hello!,
Check the FEMAP version, modern versions like V2401 are really robust when dealing with geometry.
In any case, don't worry in excess: after extending all surfaces run command GEOMETRY > SOLID > CLEANUP and FEMAP will remove all etra points.
Alternatively, in the MESHING TOOLBOX > FEATURE REMOVAL > POINT allows you to select a point and remove from the model.
Best regards,
Blas.

Awesome, thank you Blas! I've not tried the clean up tool before , so it'll be interesting to use.
Cheers.

These redundant points, and curves ... if they aren't meshed they aren't part of the FEM , so who cares ?

If you turn off "Update Surface" from Geometry > Curve - From Surface, then in the meshing toolbox when you extend a surface to the solid, it will not imprint the intersection onn the surface of the solid. Either way you will eventually need to do a nonmanifold add before meshing.

This is just an alternate method to try if interested.

Hi TG_eng,

Awesome! That's exactly what I was looking for . Thank you very much. You've saved me a lot of faffing about. bigglasses
