I want to cut out series of holes all over this surface. I don't know proper procedure to do so. The circles must be projected properly means they need to be projected into unfolded surface and cut out of the surface and then to be folded again and gain its first shape.
Please guide me by including your file. I need to study from the file.
I created a test surface and saved it in STEP and SOLIDWORKS 2018 native PART file.
