Sounds like you already have the same model saved in your Windchill Workspace. You have a couple of options here.
- Do these models also exist in your Windchill Project? Have they been Checked In?
YES - You could rename the local files before saving them to a Workspace
YES - You could create a new Workspace and save the models in the new, empty workspace.
YES - If the models exist in your Windchill Project, you need to pick Tools Synchronize from th Workspace menu
This will let you update the Workspace model and Synchronize it with the Windchill Project model
YES - You should be able to pick OK an override the workspace files since that is the default action presented in the Conflicts box
Windchill requires you to use unique names for all CAD files. For instance, you cannot create bracket.prt multiple times. The first bracket.prt checked into Windchill is the winner. All other brackets will need a new name.
