In the deposition mode shapes are added to the 3d design in a surface based model. For any location of the design a surface hight is defined. Depositions are made in top of the surface. These feature are available to create 3d shapes:
Add add a 3d shape with a contant thickness on top of the existing surface. An edge cover can be set in procent.
Fill to eight is similar to the deposite feature, but 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. Just the surface data is adjusted. In this way structure like air bridges and other opject inthe air can be created.
will reset the surface model to zero.
