![]() ![]() In traditional contour shape ruler copy milling and havig people with these skills around, this was an absolute acceptable solution to invest this time. The usual way in a prototyping workshop for furniture and even when eroding steel tools with copper master in tooling to handsand out the smooth blend between a "technical" radius and the surface. My usecase is a tabletop 2D contour shape. I had to adjust the control points by hand. As you said it is a bit cumbersome but worth the effort if you aim at real world production with CAD/CAM. ![]() I indeed took the way to extend the curvature into the flat surface and used the G4 level. You find some content on "Curvature continuous rounding" in the context of SolidWorks, Catia and Alias, but the findings are rare. When playing with the options and exporting the rounded shapes as DXF and check in other software, I get just a plain stupid radius. I found the facetting schemas in the FormZ docs and rounding tools, but this seems it only affect visualisation. I searched the FormZ docs, forums (old too) and the web but did not find any hints related to FormZ, maybe looking for the wrong term. In a complex CADCAM workflow it is not the best idea to do this manually both CAD and after milling. I the real world this is mostly smoothed out by professional modelmakers. The purpose for me is actually to smoothen out the join of the radius shape and planar surfaces to avoid the usual visible ugly "frontier" when the surface goes from planar to a constant bending. I am not sure if this was integrated in stitch rounding (makes more sense for Nurbs) or simple and controlled rounding. I can manage to meet my needs wit a sequence of manual operations, but that is not the point here!Īs far as remember there was maybe a way to create Class-A curvature continuous rounding in older versions of FormZ (I use it really for a long time starting with 3.x or so). My use case is a prominent smoothed out edge rounding with a large 75mm radius at the edges of a table.
