Separate variables from constraints
List which dimensions or rules may vary and which conditions must remain satisfied. Access, structural interfaces, manufacturing limits and approved boundaries can matter as much as geometry. Agree the distinction with the responsible team. A visually impressive option is less useful when the model allowed it to violate a condition the project never intended to change.
Keep the model understandable
Name parameters in a way another user can follow and explain their units and dependencies. Use sensible input ranges and make invalid combinations visible. A parametric definition should help the team explore a question rather than become a hidden chain of calculations that only its author can operate.
Check the output against the original question
Review representative alternatives, not only the most visually attractive result. Confirm that the constraints still hold and the model has not simplified away the interface that mattered most. Preserve the input set and assumptions behind a selected option so the study can be reproduced when the project changes.
Bring it to the next conversation.
- Name the variables and fixed conditions.
- Make invalid inputs visible.
- Save the assumptions behind the selected option.
