When you remove a 3D model from Pythagoras Web, the 3D model is also removed from all assets types that use it, meaning that all assets of that type are converted to 2D assets.
To remove a 3D model from Pythagoras Web:
Open an asset type. For more information on how to do so, see the section "Open an asset type".
Go to the asset type card (see image below).
Click the tab called "Appearance" (see the first image below). Clicking the tab called "Appearance" will allow you to define the appearance of the asset type you are working with (see the second image below).
Click the tab called "3D model" (see image below).
Go to the list of available 3D models (see image below).
Click the 3D model you wish to remove (see the first image below). The 3D model you click will open (see the second image below).
Click "Delete" (see the first image below). When you do so, a dialog will open asking the following question: "Are you sure you want to delete this 3D model?" (see the second image below).
Click "Delete" in the dialog (see image below). When you do so, the 3D model you are working with will be removed from Pythagoras Web.
