Design Space Generation - Bookshelf

Goal of this tutorial

Get familiar with the geometry tools
Create a simple Design Space fast

To start an optimisation either a geometry can be imported or created with the MSC Apex Modeler. In the following the geometry generation for the Bookshelf with the MSC Apex Modeler is explained step by step:

With the Geometry Create Tools many different sketching tools can be selected. To create the Design Space for the generative design Bookshelf the Polyline Tool is needed. To create a sketch a plane (in this case y- z-plane) must be selected.

After selecting the plane, a part inside the model tree is created automatically
On the right-side options for the Polyline Tool can be set up (e.g. grid size)
With the Polyline Tool the following sketch is done

After finishing the sketch, the tool can be closed
- The sketch automatically converts into a surface
With the Push/Pull tool a 3D geometry is generated
- In this case the surface is pulled by 150 mm

To create Void Spaces another sketch is needed
- Therefore, the center point circle tool is chosen from the sketching tools and the surface of the 3D geometry as the new sketching plane

Three circles are created with a radius of 5 mm

After closing the tool three new surfaces are created
With the Push/Pull tool the surfaces are selected and pushed completely through the 3D geometry
- This results in holes inside the geometry which are Void Spaces

To create bolts for the fixation of the bookshelf the Void Spaces are used as a starting point. They are extended using a new sketch on the same plane with slightly bigger circles with a radius of 8 mm
- This time the new created surfaces are pushed only 130 mm inside the geometry
- This creates sections which can be later used as Interfaces and therefore Non-Design Spaces

Another option to create Void Spaces is to generate new solids and to subtract them with a Boolean operation from the already existing solid

You can find the created Design Space here:

With these steps the Design Space for a Bookshelf is created and the optimisation model setup can start which is described here.
