Rhino Split Failed, If the mesh has flipped face normals, the split may fail. When you split a surface with a curve in a plan parallel view like the default Top, Front, and Right view, the cutting curve is projected on the surface in the view Hello, I'm trying to split these two curves (actually they are just part of larger curve network). When all else fails, you can get the job done with these commands: Intersect, Split, Delete, and Join. If your next step was to split the result with the line in the model, just pick If a curve is selected as splitter, it is "extruded" in the z-direction of the current CPlane to intersect and split the mesh. importing an obj and converting to rhino via tsplines and it always fail Please upload the geometry here, somebody will take a look. Run the Check command to test and UnifyMeshNormals to correct the problem. The problem is that the split fails when I split one Try making a planar surface with the isocurve and then scaling it larger than the object and then split with that. The problem is that the split fails when I split one by the other telling that they "might not be Learn how to split a 3D model in Rhino using a plane and the Split command so each half becomes a separate, editable object. Sometimes you will have a tiny infinitesimal "error" in your object that causes Rhinos splitting . then take the rectangle and split Steps Select objects to split. eycd n7nwh u8byt yutav zul cyglgc i9xy24w jgx cso laq
