Sketching Contents Creating Sketch Offsets on 3D Geometry Surfaces You can use the Offset on Surface tool to offset 3D model edges and model faces in a 3D sketch. Enhancements to the Segment Tool You can use the Segment tool to create equal length segments in splines, parabolas, ellipses, partial ellipses, and conics. Prevention of Accidental Micro Lines A dynamic buffer zone helps to maintain a consistent zone in which the click-click sketch mode results in the expected geometry with fewer cases of accidental micro lines. Shaded Sketch Contours You can use the Shaded Sketch Contours setting to view closed sketch contours and sub-contours as shaded entities. You can drag, resize, and apply relations to shaded sketch contours. Extruding Shaded Sketch Contours
