The shaft and pulleys share a common centerline. The constraints of the key are set in relation to the keyseat. A constraint in computer-aided design (CAD) software is a limitation or restriction imposed by a designer or an engineer upon geometric properties [1]: 203 of an entity of a design model (i.e. sketch) that maintains its structure as the model is manipulated.
Geometric constraint solving is constraint satisfaction in a computational geometry setting, which has primary applications in computer aided design. [1] A problem to be solved consists of a given set of geometric elements and a description of geometric constraints between the elements, which could be non-parametric (tangency, horizontality, coaxiality, etc) or parametric (like distance, angle ...
SolveSpace is a free and open-source 2D/3D constraint-based parametric computer-aided design (CAD) software that supports basic 2D and 3D constructive solid geometry modeling. It is a constraint-based parametric modeler with simple mechanical simulation capabilities. Version 2.1 and onward runs on Windows, Linux and macOS.
With direct modeling, once a sketch is used to create geometry it is incorporated into the new geometry, and the designer only has to modify the geometry afterward without needing the original sketch. As with parametric modeling, direct modeling has the ability to include the relationships between selected geometry (e.g., tangency, concentricity).
These processes optimize certain design objectives against a set of design constraints, allowing the final form of the designed object to be "found" based on these constraints. [4] Parametric tools enable reflection of both the associative logic and the geometry of the form generated by the parametric software.
Cobalt is Ashlar-Vellum's top-level product for 3D modeling and CAD on Mac and Windows. It integrates parametric wireframe, freeform surfacing, feature-based solid modeling and photo-realistic rendering all using the Vellum interface. Everything in Cobalt is history-driven with associativity and 2D equation-driven parametrics and constraints ...
Granite [6] is developed by Parametric Technology Corporation. C3D Modeler is developed by C3D Labs, part of the ASCON Group. [7] [8] CGAL is an opensource Computational Geometry Algorithms Library which has support for boolean operations on Polyhedra; but no sweep, revolve or NURBS. Open CASCADE is an opensource modeling kernel.
