For NOT closed curve, any ways to just move the end point of it to the start point to make it close, while the rest of the curve is the same? Thanks a lot!!!

Hi James, If I understood you correctly, try this: import rhinoscriptsyntax as rs crv = rs.GetObject("pick up your curve") crv_degree = rs.CurveDegree(crv) stPt = rs.CurveStartPoint(crv) pts = rs.CurvePoints(crv) pts[-1] = stPt rs.AddCurve(pts, crv_degree) The problem is that your new curve mi…

I don’t know if this will work with all curves, but you might try the following: import Rhino import rhinoscriptsyntax as rs import scriptcontext as sc def CloseCrvMoveEndPt(): crvID=rs.GetObject("Select curve to close",4,True) if not crvID: return if rs.IsCurveClosed(crvID): p…

Thank you all!! But i suddenly think that the command “CloseCrv” is the best method to do it. The question is after: rs.Command("-CloseCrv"), it requires me to manually select an open curve. How can i assign an object for it automatically? Thx!!!

You could create a line between your curve start and end points, and then join that line with curve: import rhinoscriptsyntax as rs crv = rs.GetObject("pick up the curve") stPt = rs.CurveStartPoint(crv) endPt = rs.CurveEndPoint(crv) line = rs.AddLine(stPt, endPt) rs.JoinCurves([crv,line]) rs.Delet…

[image] ka293: Is there a way to do it by just drawing a new curve from the geometry? Sure. The Replace method was just to maintain the same object ID as the original. Otherwise instead of sc.doc.Objects.Replace(crvID,crvGeo) use this new_crv_ID=sc.doc.Objects.AddCurve(crvGeo) which wil…

Hello,
Can you explain why replace is necessary? Is there a way to do it by just drawing a new curve from the geometry?
