In the deposition mode shapes are added to the 3d design in a surface based model. For any location of the design a surface height is defined. Depositions are made on top of the surface. These features are available to create 3d shapes:
Add a 3d shape with a contant thickness on top of the existing surface. An edge cover can be set as a percentage.
Fill to height is similar to the deposit feature; the layer does not have a constant thickness but everything below the entered height is filled.
Similar to Fill to height but no shape is added to the 3d editor, only the surface data is adjusted. Using this tool, structures like air bridges and other object in the air can be created.
This tool will reset the surface model to zero.
