Finding a closed loop free edges

vreddy

Is there any direct or simple way to find closed  loop free edges ??

tinh

Yes, there is not direct but simple way

It is like this

 *createmarkpanel elems 1 'Select elements:' hm_blockerrormessages 1 catch {*findloops elems 1 0} hm_blockerrormessages 0 if {[hm_entityinfo exist comps ^loops]} {      #if you use hm14 or newers:      *createmark elems 1 'by comp name' ^loops      set FreeEdgeLoops [hm_findconnectedpatches elems 1]      #if you use hm13 or olders:      upgrade => version14       #just joke! try isolate only component ^loops, and gather its elems 'by attached' }

Hi tinh ,

*findloops elems 1 0   -> is not creating component named ^loops

 

It will work only for shell elements ??? (not for 1D)

 

Thank's for your reply.

 

tinh

Yes it works with shell Vreddy

Dont create free edges by *findedges

Use *findloops will create just loops

If you still want to use ^edges, try

*createmark elems 1 'by comp name' ^edges

set Loops [hm_findconnectedpatches elems 1]

 

But sometimes, free edges are not loops (example if you have a flat plate with a rib on it)

Thanks tinh.
