catchyid Posted November 21, 2024 Share Posted November 21, 2024 (edited) Hi, I have a group of points grp1_points (each 2 points share an edge, see 1st image) I use group promote to promote points to edges group, after promoting, all edges connected to points are included (makes sense, see image below) my goal is to select only the vertical edge between the 2 original points, after testing, checking "include only elements on the boundary", I get this result I want, BUT I don't understand what makes other edges on the "boundary" (i.e. these edges are shared between other primitives, so what make them on the boundary?) thx question_groups.hiplc Edited November 21, 2024 by catchyid Quote Link to comment Share on other sites More sharing options...
Aizatulin Posted November 21, 2024 Share Posted November 21, 2024 If boundary means "surrounded by group elements" then it is the correct behaviour Quote Link to comment Share on other sites More sharing options...
