Modeling USB connector
Step 3
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

I appreciate the tutorials you put in your blog…it’s truly wonderful.
Excellent tutorial, thank you. Any chance you will post a V-Ray render of it?
could happen
I am a beginner. Unfortunately I have no idea how you can insert a picture on Rhino. Can you please add some info about how to make the first instruction of your tutorial work? Tanks for your understanding and help in advance.
Dreja:
Click in the viewport which you want the picture in. Go ‘View->Background Bitmap->Place’ Then follow the prompts to size and place the image
is there an advantage to doing the Sweep2 step, vs just lofting the two curves?
If you’re referring to the Sweep 2 rails on the first page, second from the bottom… I think using the 2 curves and cross rails allows you to more easily constrain the surface, but I could be wrong.
thank you for the tutorial. its easy to follow and understand. quick question are there any easy ways of isolating objects?
Can somebody help with trimming of upper surface? Can’t get the result on picture http://www.rhino3dhelp.com/wp-content/uploads/2008/11/usb_15.jpg, only as on picture http://www.rhino3dhelp.com/wp-content/uploads/2008/11/usb_15.jpg... Maybe author of tutorial can clear this moment?..
Thanks in advance!
well, all you have to do is select desired surface and corresponding curves. That is, if you select the upper surface then you need to select the curves that are on that surface. Once you select those, run the trim command and then click inside the curves that way you create holes in it.
As for the inner surface, you need the opposite. You need to trim the outer part of that surface. So you click on outside of the curves.
If you still don’t get it, I’ll record a small clip for you.
