I created this design by making the "mouse sketch" in the CSWPA-Surface Sample Exam more detailed. I created a roadmap by going over the "import sketch" given in the sample exam, and then filled in the necessary places using the "Filled Surface" command. There were 2 important elements that I paid particular attention to while creating the piece:

Knit Surface connected the surfaces I created into a single piece and enabled me to use commands such as "Filet", "Create Solid".

The other was the "Split Line" command in the Curves tab. Thanks to this command, I was able to project any drawing I created on curved surfaces. In this way, I was able to perform cutting and thickening operations on curved surfaces.

Below I share the looks of this model, which I recommend everyone to do to test themselves before taking the CSWPA-Surface exam. Good work .
