OK I solved the above problem, I changed my way . I nolonger use the end point of surface . I offset the edge of surface, then divide the new offseted lines and use curve go long them. so . the curve is purfect!!!!!!!!!!!!!!!!!!!!!!!!!
but new question: how to do the " surface form planar curves" command in gh?? may be I have to use vb to do that??? On Apr 14, 1:44 am, Grandtour <[email protected]> wrote: > my question is on this > picturehttp://picasaweb.google.com/lh/photo/TudgAkB8ds1dQkb72G9KdQ?feat=dire...
