Creating a critical dimension for optimization

A critical dimension is a specific part dimension, which must meet the defined tolerances. A critical dimension is defined by the distance between two specified nodes, and is used to study part shrinkage and warpage.

  1. Click (Boundary Conditions tab > Dimensions panel > Critical Dimensions) and select Optimization from the drop-down menu.
  2. If the model nodes are not displayed, in the Layers pane, select the check box next to the layer(s) containing the model nodes.
  3. Click the node on your model and the ID is placed in the Node 1 box automatically. Alternatively, type the ID of a node that defines one end of the critical dimension.
  4. Repeat the process for the second node.
  5. Type a name in the Name box that is unique to this study.
  6. Click Apply to create a critical dimension. The critical dimension is placed in a separate layer containing optimization critical dimensions. This layer is located in the Constraints layer folder.
  7. To close the Tools tab, click Close.
