Yeah, yeah, I know. You must be thinking “Another rim tutorial”. Well, first of all, I’m pretty sure you will learn even one new command in this tutorial.

Video tutorial  for modeling car rim.

STEP 1

Insert the first reference image into the background of your Right Viewport. I made it 50 grids wide. You can set the background image to be in color, and remove grid with grid command. Using polyline (or just line) command, make simple straight lines according to the background image.

the parts that aren’t needed, and fillet the intersections with the radius of 2. And offset by 0.4 inside.

After you made a profile for the rim, insert second reference image and using scale background image and move background image commands, position it so it somehow fits your profile curve.

Using Curve: Interpolate points command, create another profile… like on the image below. You can create one polyline in the middle of the rim.

Trim off the parts of curves you don’t need, and on the inner side of your spoke, fillet the straight line and curve with 2.

NOTE: at this point, I have rotated my curves from front view by 90 degree and positioned so the far right end of curve is in origin (0,0)

Using Remove Knot command, remove selected knots. So you end up with uninterrupted curve, so when you try to explode it, it says this: “Cannot explode single curve segments.”

  1. Good job on tutorials, really helpful thanks!
    A few nit-picks:
    1. The video quality, really tough to see the lines, and text, and pretty much anything 🙂
    2. The “screws” on the rim, are actually called lug nuts (at the very least bolts), and there are no bolts/nuts with 5 sides! Maybe on Mars. There are always 6 sides. That’s just too funny.

    Again, thanks a great deal on the tuts!
