Introduction
1. Standard Overview
GB/T 36341.2—2018 specifies the features and constraints in shape modeling information representation, and is applicable to CAD, virtual reality and other fields. This section explains in detail the definition and application of constraints in each dimension.
2. Comparison table of standard frameworks
| Standard dimensions | Definition scope | Constraint type | Applicable scenarios |
|---|---|---|---|
| Basic requirements | Feature composition and identification | - Feature element constraints - Feature combination constraints | CAD model design |
| Feature elements | Points, lines, surfaces and their combinations | - Geometric shape constraints - Parametric equation constraints | 3D animation production |
| Feature combination | At least two elements | - Spatial relationship constraints - Semantic association constraints | Virtual reality scene construction |
3. Detailed explanation of feature constraints
Coincidence constraints:Require that associated feature elements completely overlap. For example, two arcs completely overlap within a specific parameter domain.
4. Implementation suggestions
Enterprises should:
- Follow the feature constraint types defined in the standard
- Choose appropriate constraint parameters based on actual needs
- Use professional tools to verify the model
