This post explains how to enhance the visible status of incomplete assembly constraints and how to change the Assembly Feature (Cut) Considerations to reduce memory usage, as well a few tips to help with large assembly management. This content is intended to provide users with easy-to-use, actionable tips and tricks for how to use Creo more effectively. These tips come from Steve Meyers and Evan Winter, two Creo experts in our training group.
1. Previewing Assembly Constraint Status
Incomplete assembly constraints can be difficult to identify when previewing the assembly constraint status. In the example shown to the right, the part of the model that is partially constrained is clearly highlighted in red. You can enhance the visible status of incomplete assembly constraints within your model by following these steps:
1. Open the System Colors dialogue box by opening the File menu, selecting Options, and then selecting System Colors.
2. Open the Graphics dropdown menu.
3. Change the color selection for Secondary Previewed Geometry.
