Generate a Design
After you completely define the study and perform topology optimization, you can create a Generative Design feature (GDF) with the 
Generate Design command.
Generate Design command. | If you want to explore multiple designs with the study definitions, you can send the study to Generative Design Extension. For more information, see Generate Designs using Generative Design Extension. |
A Generative Design feature (GDF) is a new design based on the results of the optimization. When you construct the geometry from the results of the optimization study, only the one component that you optimized is constructed.
There are two types of geometry output:
• Tessellated
The optimized geometry is constructed as a Facet feature, and the geometry that is excluded from the optimization is copied as independent geometry (the neutral feature). You cannot perform parametric functions on the facet feature, but you can perform basic edits.
A faceted model might be all you need for models with relatively simple geometry.
• Reconstructed
The optimized portions are constructed as a Freestyle feature, and the geometry that is excluded from the optimization is copied as independent geometry. The Freestyle feature is solidified.
This method constructs a full B-Rep (boundary representation) model. You can use Creo Parametric functionality on all the geometry in the newly constructed model. It is recommended to start with the 
basic Resolution level for reconstruction. You can then select 
,

Once the study is fully optimized and the result has successfully converged, the Generate Design option becomes available. Click Generate Design to create GDF in the same or a new part. A new body is also created in the Model Tree under the Bodies node. This body contains the GDF.

1. Click Generate Design. The Generate Result dialog box opens.
Generate Design. The Generate Result dialog box opens.2. From the Result output list, select Current Part.
3. Select the type of Geometry Output:
a. Tessellated
b. Reconstructed – Do the following:
a. Select the Resolution level for the reconstructed design. A higher level of resolution creates geometry that is closer to the underlying facets, but the reconstruction is slower.
b. If you select , , or , select the Subdivide the reconstructed shape check box to subdivide the reconstructed optimized design according to the selected level of resolution.

If you want to copy only the resulting geometry, select Copy only the result geometry. The bodies that are not part of the study definition are not copied.
5. Click Generate. The Save a Copy dialog opens.
6. Select the location to save the part and click OK. The generated design opens in a new Creo Parametric window.
After you create GDF, you can edit its study definition and perform topology optimization.
