In one of my plan files, I often encounter a message that presents repeatedly and says:
"The material "___" was duplicated. It was renamed to avoid confusion."
What is causing this and how can I prevent it?
This message will display when the program detects multiple materials in a plan file that have the same name. To prevent the message from continuing to display, you can purge unused materials from the plan.
To purge unused materials from a plan
Open the plan file in question.
Select 3D> Materials> Plan Materials from the menu.
In the Plan Materials dialog:
Scroll through the list of materials on the left and notice the number of materials that do not have a check-mark beside them.
Click the Purge button.
Notice that the materials in the list with no check-marks are now gone.
