hey robbur, in you are reading this, your tutorial seems to be offline, is this temporary or have you removed it? Just wondering, I was gonna go through it again for a technique I might use at work here. So I was kinda wondering where it went?

The radius on the part section was spun off the bottom face, extruded through the bearing and manually cut at the other intersects, knife/snap. I first rotated the bearing 1/2 a facet.

I haven't tried the Geom script yet. It sounds useful, I will look it up.

Well it is a really cool tutorial, I really like to see how blender is used in an engineering environment, since that happens to be my new job. I don't engineer, but I recreate loads of stuff in blender for marketing renders. Mostly pipeworks. but this tut shows quite a lot of cool stuff.

Might I add, i think with the knife and snap combo, you still have some, a very very slight inaccuracy. if you look for the geom script, with it you can intersect all kinds of edge/face combinations etc. It wouldn't be a 100% accurate in this case either since a circle is only as much a circle as the amount of segments it has. But it saves me a lot of time every now and then.

I was looking at your render again, and I noticed something. I don't think it is described in your tutorial, how did you cut out half of the "rings/cases" and give them a round fallof where they intersect/make a 90degree angle?
Manually cut temporary faces? Boolean? or hack?

Wow!!! Thanks for all your comments; I am overwhelmed by all the positive comments I have received.

I only found blender around 2 years ago. I have been using Solidworks since 2002, which helped.

You are right that is a bit of a hack. I haden't stumbled across the knife/vertex snap until I was looking for ways to accurately cut the cage (after Part 2 was finished). I might re write that bit and just cut new vertices on the circle from the horizontal lines.

Thanks again

OMG, it is one of the best tutorials that I've saw !
Brilliant, Brilliant !! Nice design for the web site too.

Looking through the first part of this tutorial, this is how I model most of the stuff at work here.
With a certain exception though. When he rotates certain vertices in the circle to be close to the edge, and then scale them to 0 to fit the edge using 3d cursor pivot, I would use the GEOM script to find the intersection point between those two (actually 6 in total) edges. I think that's a tad more precise?

He's got a pretty good site, and this tutorial is really clear. Nice addition…

Cool point of view. Using blender in engineering work. I've had a brief look at it, when I get better time I will study it more to pick up a few new tricks.

BTW did you know that you kan move your 3D cursor arond from the View->View Properties menu (when you are in editmode). This way you might not need to extrude some measurements, and move your cursor.

Keep up writing tutorials!!
