When you work with Design Accelerator generators and calculators, Design Accelerator detects errors in models, constraints, and calculations. The error does not harm the geometry. It informs you that two components cannot be constrained or calculated in the way you attempted.
When an error in a model, constraint, or calculation is detected by Design Accelerator, an error message in the Design Accelerator Doctor dialog box explains it. To edit generator data to resolve the error, you click Edit to open the corresponding generator, or accept the error by clicking Accept.
