As far as "smoothing" goes, I only see it available with the "primitive" tools. Once you 3D Add/Subtract and they become a TC Surface object, "Smoothing" is no longer available. DesignCAD objects show up in TC Deluxe as TC Surface.
Thanks John. You've probably seen my rants about the new DesignCAD Solid Surface in version 24 which I understand is a TC Surface.
Anyway, regarding the smoothing. DesignCAD has a more natural synergy with SketchUP then it does with TurboCAD. In DesignCAD we only have facets (planar regions), call them surfaces. They can be combined into a DesignCAD solid. SketchUP does the very same thing. Everything in SketchUP is merely edges and surfaces. And they too (SketchUP) have modeled a SketchUP solid as a composite collection of surfaces that hold water (they validate this watertightness to be a solid , DesignCAD doesn't). The conceptual parallels between the two programs at this entity primitives level is one to one.
TurboCAD on the other hand vigorously chases and and in some areas leap-frogs AutoCAD thinking with the Andy, Charles, Ian's System
solids. That path offers solid modeling at a different complexity level offering parametric capabilities, assembly sequences etc.
But the point of my asking you is that DesignCAD users are looking for a least-work method of getting quality rendering. Having to fix an import in another program or getting clunky curved surfaces ruin the purpose of using a second program. Hence the magic of the "smoothing" feature. And when and if we get those in RedSDK . . .
