Not educative but if you are pressed... :)

You have a lot of models here to load (STEP, SAT, IGES) for Moi ;) (i don't know the best format ?

for example this one.. https://www.mcmaster.com/6484k104 (i don't researched your exact model :)
(scroll choose format and click Save (no need to be registered)


I had loaded another thing - that is terrific! :)

Hi Frederick, Construct > Offset can be good for shapes that have a constant thickness to them.

I'd probably go like this - circles:



Rectangle:




Boolean union those together:



Construct > Offset to generate an offset curve:



These can now be extruded:



Or another possibility is to extrude the outside only to start with and then select the top and bottom faces and use Construct > Offset > Shell:

Hi,

Thanks very much for making that video.

You have saved several steps for me.

Hi,

That looks like a good approach.

Some of my belt paths are a bit more complicated than a simple loop.

One I am working on now has five "pulleys" in a "T" shape. Another has eight in a "H" shape.

I will have to take what I have learned today and see how best to apply it.

I also like the method Michael just showed. Nice and simple.

Hi,

Very nice models.

Thanks.

Hi Fredrick,
Yeah, "2 pulleys" is a fairly basic belt. "H" shaped five pully belts would be a "little more work", but shouldn't be too much, using Michaels offset methed.

Basically would have to identify "inside pulleys and outside pulleys" then offset one or the other first... connecting quads and trimming wont be able to be avoided at that point, but shouldbt really take much time.

If you feel like you are struggling, post back and get some more direction. It can really make it so much nicer to see others methods!!!!

Later!

Hi,

This is a screen shot of what I am working on the prompted the question about belts.

There are five simple belt loops and the single "T" shaped one.
