How to mark the lines connected to surface?

Altair Forum User

How do I mark the lines which surround/are connected to a surface?

*createmark lines 1 'by surfs' 1 2 3

...doesn't work for me.

For surface edges (not lines) you can use this:

*createmark surfaces 1 ...

*findmark surfaces 1 113 1 lines 0 2

This gives you in mark 2 (hm_getmark lines 2) the edge IDs.

Please check the help page of *findmark for details on the third parameter (here 113)

Hello Stefan,

When I check the HM v10 help, I find the third parameter for *findmark is 'function' & has permissible values of 0 & 1. Could you please provide further details regarding you use of the values 113.

Thanks,

there are several ways to accomplish that:

hm_createmark lines 1 'by surface' $surfaceList;set linesList [hm_getmark lines 1];

where surfaceList contains the ids of surfaces.

or you could use 'hm_getsurfaceedges'. check the hM help for a this command usage
