System Model Catalog
Choose a published system model from the shared media chooser.
System library contains published built-in 3D models. It appears in the model chooser only when system models are available. The chooser also separates This project and My library for your own media; system models are pick-only items rather than account files you can rename or delete.
Open the model chooser
Open the model picker and select System library if that tab is present. If the published catalog is empty, the tab is hidden; this does not mean your own project or account models were deleted.
Search and choose
Use Search to find a model and select its tile. The picker resolves the published model and its catalog scale before entering placement. Available items depend on the published catalog, so do not assume a particular category or model is included.
Place the model
Move to the intended location in the drawing or 3D view and click to place the model. Check its size and orientation. You can transform the placed object with the supported object controls.
Use your own asset when needed
Choose This project or My library to use stored project/account assets, or import a supported file. Your own imported model and a system-catalog model use different library sources even though the picker provides one placement workflow.
