Parametric
Make the key dimension a parameter and a new size is one number away
What this actually means
- Numbers you use over and over — phone width, plate thickness, hole spacing — get set in one place.
- Dimensions can relate to each other: keep hole centres two wall-thicknesses from the edge, and they follow when the wall changes.
- One model, a whole range: five sizes is five numbers, not five models.
- Parameters carry ranges and units, so an impossible value is caught immediately instead of silently producing a broken model.
Common questions
- Do I have to write formulas?
- No. 「Make phone width a parameter」 is enough, and relationships are just as spoken: 「keep hole centres two wall-thicknesses from the edge」. You can write them yourself in the code view if you prefer.
- Will changing a parameter undo my manual tweaks?
- No. Manual work is part of the model; a parameter only drives the dimensions bound to it.
- Can I export a whole range at once?
- Yes. Give a list of parameter values, generate the batch, export them. Ideal for phone cases across models or clamps across pipe sizes.
