OpenSCAD is cool and I do use it when it is the most convenient tool, but I find it to be incredibly slow, and if you don't want the output to be all blocky polygons (which you can only achieve by increasing $fn AFAIK) then it gets even slower.
It also suffers from not having any general-case way to fillet or chamfer edges, which means you have to bear your fillets/chamfers in mind throughout the entire design if you want any (which is why most OpenSCAD designs don't bother).
- dTal 5y agoThere is actually a general-purpose way to do fillets in OpenSCAD, using a slightly Rube-Goldberg combination of booleans and minkowski sums. Unfortunately it is, again, far too slow to be usable in 3d at anything like an acceptable resolution. It works great in 2D however. http://www.scorchworks.com/Blog/openscad-modules-for-automatic-fillets-and-radii/ http://www.scorchworks.com/Blog/openscad-modules-for-automat...
- ur-whale 5y ago> it is, again, far too slow It also fails miserably as soon as the geometry you're trying to fillet is complicated.
- dTal 5y agoIt shouldn't? The one bright part of it is it's completely general. I've never known it to fail - although again, it's too slow to be useful in 3d.
- jstanley 5y agoIt's general if you want an equal fillet on every edge, but it's not "general" in the sense that you can apply fillets and chamfers of different sizes to different edges. Unless you plan to do so from the very start and design your entire part accordingly.
