  2. Parametric design - Wikipedia

    en.wikipedia.org/wiki/Parametric_design

    It is the basis of Digital Project, a parametric design software by Gehry Technologies. GenerativeComponents: A parametric CAD software developed by Bentley Systems [23] that allows users to model and manipulate geometry, apply rules and relationships, or define complex forms and systems through algorithms. It supports many industry standard ...

  3. Constraint (computer-aided design) - Wikipedia

    en.wikipedia.org/wiki/Constraint_(computer-aided...

    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.

  4. Solid modeling - Wikipedia

    en.wikipedia.org/wiki/Solid_modeling

    Parametric modeling is obvious and intuitive. But for the first three decades of CAD this was not the case. Modification meant re-draw, or add a new cut or protrusion on top of old ones. Dimensions on engineering drawings were created, instead of shown. Parametric modeling is very powerful, but requires more skill in model creation.

    A 2D CAD drawing A 3D CAD model Computer-aided design ( CAD ) is the use of computers (or workstations ) to aid in the creation, modification, analysis, or optimization of a design . [ 1 ] : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to ...

  6. Geometric constraint solving - Wikipedia

    en.wikipedia.org/wiki/Geometric_constraint_solving

    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 ...
