Now, lets make an USB logo on the body object. First make a rounded rectangle like on the image below and offset it to inside by 0.1 units like on the right image:
Project those two rectangles onto the object, and delete all except the two on the upper surface:
Using trim (or split then delete the surface we don’t need) create this:
You will need to move the inner surface down a bit. Do it from front or right viewport and by 0.05 units. And then, using Blendsrf command, blend the two surfaces:
Now, you can explode the whole object, and isolate just one surface like on the image below and using lines and circles trace the USB logo:
You need to project that logo onto the surface, and using split command, split it with the usb curves. Move the usb surface up by 0.05 units.
Using extrudecrv, extrude the projected usb curves up by 0.05 units.
Now, we will fillet the edges with filletedge command and 0.04 units as fillet radius:
You should end up with this:
And this is it! You modeled yourself an USB connector. Now, all you need is to render it 😉
