Step 1: Reimport your already optimised geometry
The optimised geometry can be reimported into a new project or into the already existing optimisation project. For this Tutorial the project of the Bridge is used.
...
After importing the non-intersected STL-file the optimisation result is displayed as a Faceted Solid inside the model tree.
...
Step 2: Mesh to CAD
With the Facet Body to NURBS Geometry Tool under the Geometry Edit Tools the STL-file can be transitioned to a CAD-file. Therefore, the Automatic Size Calculation and the Partition Preview can stay active. With the middle mouse button (MMB) the operation can be executed.
...
From time to time depending on the geometry some NURBS patches might fail. These will be displayed in the status bar as well. If this happens the geometry can be repaired manually. How this works is described here.
Step 3: Geometry Cleanup
We recommend to use the Geometry Cleanup Tools after the NURBS CAD-Geometry is created.
...
Step 4: Creation of functional surfaces and sharp edges with Boolean operations
To create the final CAD-Geometry all functional surfaces and sharp edges have to be created with boolean operations. The best way for this is a boolean intersection between the retransitioned optimisation result and the Design space of the optimisation. A copy of the Design space is needed for the following operation.
