I’m trying to make a C# component that will offset planar curves consistently regardless of curve directions.
The process would be:
- Close all curves, if not closed.
- Get center points of curves.
- Get normal vectors of surfaces from curves
- Offset curves
I asked a similar question before here, but the curve offset method seems changed in Rhino 6.
I’m embarrassed that I didn’t make much progress on coding since then, but can you help me write this component in C#?
//Create surfaces to get normal vectors from surfaces using ClosestPoint method. Brep crvBreps = Brep.CreatePlanarBreps(crvs, 0.1); //Get centroid of curves AreaMassProperties AMP = AreaMassProperties.Compute(crvs); Point3d cen = AMP.Centroid; //Get Vector3d normal using Brep.ClosestPoint method Vector3d normalCrvs; Point3d cPoints; int ci; double s; double t; crvBreps.ClosestPoint(cen, out cPoints, out ci, out s, out t, 100.00, out normalCrvs);
I skipped the step 1 for now and am trying to get normal vectors from surfaces using Brep.CloestPoint method. Can someone let me know I can make this work?
Once I get normal vectors, I’m thinking to use Curve.Offset Method (Point3d, Vector3d, Double, Double, CurveOffsetCornerStyle).
