- Geometric Constraints: These define geometric relationships between faces, edges, and points. Examples include:
Concentric
(aligning two circular features),Tangent
(ensuring two curves are tangent to each other),Colinear
(aligning two edges), andFlush
(making two surfaces coplanar). - Mate Constraints: These are used to define more complex relationships between components, such as
Fixed
(one component fixed relative to another),Insert
(inserting a cylindrical part into a hole), andSurface Contact
(contact between arbitrary surfaces). Mate constraints are more powerful, handling degrees of freedom. - Insert Constraints: These are specifically designed for inserting cylindrical components into holes, automatically accounting for the cylindrical fit and eliminating rotational freedom.
- Symmetry Constraints: These ensure that features are symmetrical about a plane, a very useful tool.
Proper constraint application is vital. Over-constraining can lead to model instability, while under-constraining leaves components too free to move. I carefully plan my constraints to ensure a stable and functional assembly.
For example, when designing a simple table, I might use Flush
constraints to align the table top with the legs, and Insert
constraints to attach the legs to the tabletop.
