To get the desired body profile, we need to make some changes by moving control points of the T-Spline surface using tsManip. Select all lines and enter the tsControlPolygonToSrf command.Ĭheck the preview option to ensure the surface is correct. Now the curves are ready to be transformed to a T-Splines surface. STEP5 – T-SPLINES SURFACEīefore generating the T-Splines surface, we need to be sure that we only have the lines we need for this, I usually use: first, ungroup all, then split selected curves against each other ( tsSplitCurves ), select duplicate curves ( SelDup ) and Delete them. These inner lines are not necessary for the tsControlPolygonToSrf command (next step). Remember to delete all the internal lines after extruding. Now we need to extrude these lines with tsScriptExtrudeControlPolygon (Thanks JB and T-Splines for this amazing tool!) in order to get a 3D control polygon. Once we have the control polygon profile, we need to connect the points.Remember that the ideal thing is to have rectangular regions (keep that rule of thumb in mind when you draw the curves.)Įach line intersection will determine where the control points will be on the surface. In step 5, we will use this control polygon to generate a T-Splines surface with the same profile of the native curves. Use ExtractControlPolygon to extract the control polygons of the curves. The idea is to have a smooth transition between the body and the hearts, with no sharp edges. This particular design consists of two hearts connected by the body of the ring. For me, the best way to get the right profile is by designing it undeveloped. STEP 1 – WIREFRAMEįirst, draw the main profile of the ring using Curve. Type these commands in the command line of Rhino to run them. The model can be downloaded at In this tutorial, anything in Blue is a Rhino command, while anything in Red is a T-Splines command. You can follow the model’s progress by selecting the differents layers in the file. The best way to read this tutorial about how to model a ring using T-Splines is by looking at the 3D model at the same time. T-Splines and Rhino 4 offer an easy way to create smooth, gap-free organic models for jewelry design. Organic Modeling for Jewelry Design with T-Splines and Rhino® 4ĭesigning freeform objects can be difficult when working with traditional CAD software. You can download this tutorial in PDF format here. This tutorial will cover some basics of designing and modeling a ring with T-Splines and Rhino 4.
