Hello,

 

How to get the point list on the boundary of a selected surface?

 

My goal is to get the distance between the points and set the element density accordingly.

    Hi

    You can do like this

    *createmark points 1 'by surface' $surfID

    set PointList [hm_getmark points 1]

    Hi

    Use 

    set surfIDs [ hm_getmark surfs 1]

    *createmark points 1 'by surface' {*}$surfIDs

    set PointList [hm_getmark points 1]

    Or 

    *createmark points 1 'by surface on mark' 1

    set PointList [hm_getmark points 1]
