Direct Mod­i­fi­ca­tion and Vari­a­tion of Imported NURBS Geometry

Consider you have an existing geometry from another CAD system, and you want to conduct a design study with the geometry in CAESES®. Let’s assume the geometry was exported as a set of NURBS curves and surfaces, using a standard format such as IGES or STEP. The idea now is to directly modify the NURBS entities in CAESES®. This is what you have to do: Import the geometry, select the NURBS entities and activate the edit mode. Select the control points you want to vary, and create design vari­ables for the coor­di­nates. That’s it. Now you can run design studies or opti­miza­tions where the design vari­ables are changed by the CAESES® design engines. The fol­low­ing short video shows how it works. For shape changes, the design lab is chosen as design engine. It allows the user to create manual designs by using a set of sliders. Enjoy!
