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:

usb_56.jpgusb_57.jpg

those two rectangles onto the object, and delete all except the two on the upper surface:

usb_58.jpg

Using trim (or split then delete the surface we don’t need) create this:

usb_59.jpg

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:

usb_60.jpg

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:

usb_61.jpg

You need to project that logo onto the surface, and using split command, split it with the usb curves. 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:

usb_65.jpg

You should end up with this:

usb_66.jpg

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.

  2. Mitchell says:

    Excellent tutorial, thank you. Any chance you will post a V-Ray render of it?

  3. dreja says:

    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.

  4. Mitchell says:

    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?

  6. Mitchell says:

    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.

  7. Hy says:

    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.

    well im getting really mad because this usb is stupid useless and ANNOYING as well i hate it deeply and no one should need to know how to make a usb unless you work aT place that makes usbs then you really do need to know how to because if you didnt you would be fired and no one would like you 🙂 but we are getting of topic do you really think that anyone needs to know how to make a usb its useles and no one wants to make one at all!!! but if you really want to YOU SHOULD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    You shouldn’t model it, if it doesn’t interest you. But having seen all the various methods for modeling different models, it is sometimes easier to model something new using that knowledge.

    Hello Ivan,

    I wanted to know how you managed to isolate the two curves after the trimming of the two surfaces. I am new to Rhino. Thanks. 🙂

  13. Tiger says:

    Anyone? Please help…

  14. Ivan says:

    simply select the surfaces and hide them with Hide command. Actually what I did here is hide everything except two curves for easier selection and presentation for the tutorial purposes.

    Thanx. Great tutorial. I’m having trouble with the filleting of the inside edges of the ribs, down in the pocket. All surfaces are joined. No naked edges. When I fillet, it generates the fillet but it’s in pieces, normals are erratic and it hasn’t intersected and joined the surfaces. I can still see the original surface behind. I tried reducing the size of the fillet but to no avail.

    Any Suggestions?
