To Modify a non-Creo Model without Converting to a Creo Model
1. Open a Creo assembly with non-Creo models as components from the Windchill server.
2. Right-click a non-Creo component on the Model Tree and click Activate.
3. Select geometry on the non-Creo component and begin modifying the component. The Conflicts dialog box opens. It prompts you to check out the component.
4. Select Check out now from the Action list and click OK in the Conflicts dialog box.
The Confirmation dialog box notifies you that the design changes that you are about to make to the non-Creo component will not be reflected in the source model. It asks you whether you want to convert the component to a Creo model.
5. Click Do not convert and click OK.
6. Continue using the Creo commands to make the design changes to the non-Creo component.
7. Click File > Check In > Auto Check In or right-click the model and click Check In > Auto to check in the non-Creo component with the design changes to the Windchill server.
