In Design Accelerator generators and calculators, the 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.
When an error in a model, constraint, or calculation is detected by Design Accelerator, an error message displays. To edit generator data to resolve the error, select Edit to open the corresponding generator (Edit reverts the changes to the last acceptable state), or accept the error by clicking Accept.
