How to use Molding Models in Cinema 4D

Go to Cinema 4D top menu > Greyscalegorilla and click Plus Library.

On the Plus Library window, click Models tab and select "Baseboard Molding" or "Crown Molding"
then select a model and double-click to add to the scene.

- You will see the sample molding model on the viewport and on the Object Manager with a spline profile.

- Then you can use the profile along a spline with Sweep object.

Note: If you cannot see the Spline object, please go to Cinema 4D > Edit > Preferences
then Import/Export > FBX and check Curves. Restart Cinema 4D. And add the molding model again.
