Create a roundness criterion to monitor how much a specific rounded edge changes shape, following a warp analysis.
This task assumes you have set up your analysis, and that your analysis sequence includes a Warp analysis.

Make visible the model nodes in the Layers pane.
Click
(Optimization tab > Criteria panel > Roundness) to open the Roundness Optimization tool.
Select a node that is on a rounded edge.
By default, Auto select edge is applied. When you select an edge node, all nodes on that edge are automatically selected.

Enter a unique name in Selection name, that describes the selection, so you can associate it later with the selected edge.
Click Apply to create the roundness criterion.
You can continue to create additional roundness criteria, saving each selection and clicking Apply.
Click Close to close the Roundness Optimization tool.
These criteria are selected by default in the Criteria tab of your optimization analysis.
