In the following, the final result of a previous tutorial will be modified and a Two-Stage-Optimisation will be performed. In this case a strut will be removed.
Step 1: Transfer of the already existing geometry
The first step is to transfer an already existing geometry. The result from the following optimisation was used:
...
In general, every previous iteration can also serve as a Start Space and can be transferred.
Step 2: Removal of a strut
With the Sketching and Geometry Tools inside MSC Apex Generative Design a square can be created to remove one strut of the structure. The square is created by drawing a rectangle on the plane using the Sketching Tool. The Push/Pull Tool is then used to create the volume of the square.
...
Tip: In some cases it is easier to create a plane first and then draw the rectangle or the Push/Pull Tool can be used to move the rectangle to the correct location to enclose the strut.
Step 3: Creation of the Start Space
To create the new Start Space the just created volume and the transferred optimised shape can be subtracted with a Boolean Operation.
...
The resulting faceted solid needs to be exported as an STL-file.
Attention: The unit has to be in meters!
...
Step 4: Start of the optimisation with the modified Start Space
In the last step the optimisation can be (re-)started with the new, modified Start Space. Therefore, the previous Scenario can be copied.
