For the optimisation we define different areas of the geometry. These are mainly the Design Space and Interfaces.
...
The Design Spaceis the most important space and complies with the imported/created solid CAD geometry. It includes any space where material is allowed to be or has to be, to provide maximal freedom for the algorithm. If the Design Space is limited, so is the optimisation algorithm and the optimisation potential is reduced.
Interfaces are all functional faces of a model so all faces where boundary conditions are applied to. With the Interface Tool these faces are selected to create both Non-Design Spaces and Machining Allowances.
...
To realize a post processing of additive manufactured parts a Machining Allowanceneeds to be considered for all functional surfaces. These can be created in the Interface Tool so that the optimisation directly produces a manufacturable design with offsets as well as the final geometry for the CAD/CAM system.
Void Spaces are spaces within your part where no material is allowed to be and free space for example for other parts of the assembly is needed. These spaces can be easily created with the Access Region and Clearance Region Tools. Especially for realising Part Consolidation these Tools assist to prepare the Design Space and the geometry for the optimisation.
