OpenSCAD is based on constructive geometry, which means the compute complexity scales up mainly along the complexity of the CSG tree which can get very big, but the number of triangles is quite low and independent of the resolution. They are based on two different algorithms, but both should guarantee a topologically correct solid if implemented correctly. TL DR: a nice tool to add to your belt, but not a very mature environment yet, and certainly can't replace OpenSCAD yet. importing external models that don't fit the cadquery BREP-based represention is basically impossible. good for modeling mechanical parts / lousy for modeling anything organic-looking fine-grain control over tessellation (conversion to mesh) is lacking. Generally speaking, the UI is only a visualizer, and does not let you query / inspect the model in any detailed way. the UI (cq-editor) is unusable for real-world work: no perspective rendering, no graduations in ortho views, no way to measure things on the object, no way to examine the BREP, etc. cadquery has "selectors", which are a) its own weird little DSL b) very difficult to use on complex shapes c) does not support name-based retrieval: can't label things and get to them later by name. selecting parts (faces and edges) in a object is a nightmare. the underlying hierarchical nature of the object (the BREP) is forcibly hidden from the user, which leads to kafka-esque situations when one wants to e.g. For complex objects, it's hard to wrap your head around it, and the workflow it forces on you as a user does not always fit your mental model of the object. I usually prefer the CSG (arithmetic tree of union/difference/intersection + transforms + base shape leaves) to model 3D objects, as opposed to Cadquery's "draw on 2D surfaces and extrude" approach, but OpenSCAD's lack of fillets / chamfers combined with the "everything is a polygonal mesh" approach of the rendering engine is just too limiting.Ĭadquery has a lot of potential (the underlying engine uses a traditional hierarchical NURBS BREP, IIUC), but it also has a lot of shortcomings: I've started to switch to Cadquery from OpenSCAD because it lacks proper fillets and chamfers.
>I was under the impression that CadQuery sort of obsoletes OpenSCAD.
