How To Limit Autodesk To Only The Inside Surface?

To select hidden or internal faces in Fusion 360, enable Select through in the selection menu and use the “Select Other” tool to select one object that is blocked or hidden. To remove internal cavities from an STL file, delete the internal mesh features in the Mesh workspace. Autodesk’s Meshmixer is a state-of-the-art software for working with triangle meshes and 3D meshes. If defining a hide boundary and using non-destructive breaklines, enter S for Surface and select an existing surface in the drawing.

To convert Mesh without generating a face group, click the Mesh tab in the toolbar and from the modify menu. This can reduce assembly model complexity, improve performance in downstream processes, protect intellectual property, or use in larger still assemblies. To grab the outer surfaces of the castings in your image, unblock the plug-in (in Windows) and drag and drop it onto Rhino.

In edit mode, select all exterior faces by going around and box selecting, making it impossible to choose faces you cannot see. This can also apply to creating a surface defined by 3D Faces and a grading surface (pasted as an edit). To cycle through surfaces, place the cursor closer to the desired surface and press up/down arrows on the keyboard.
