Jest fer fun...

Most of the modeling was pretty straightforward, using methods that have been available for many years now. It did take several tries to get the lofts smooth enough for the TCad genie to be able to fillet the sharp edges.

Notice the spring: it's tapered and has a nonuniform pitch. I did use a fairly new TCad feature to model this item -- the Curve from Law tool, to create a path for sweeping a circular profile. Sweep paths for the hooks are hand-drawn 3D Splines.

Very impressive, but I don't think the axes match between the image and the formula.

I hadn't even noticed that vertical line, Jeff. It's purely accidental and has nothing to do with the curve. I'm gonna delete it and update the posted image.

Very nice Henry.  I'd say photorealistic.

Very nice indeed,  and thanks for the cut-away view, I do like a good cut-away.

That came out great, Henry.
You make it look so easy.
I like the organic look on the handle, did you use a variable blend?
Thanks for sharing.

Thanks, Dean. No, I lofted it.

... I lofted it.

I'm not getting anything near the same results.

I created one 2D Polyline, then Linear Array'ed it in Z and scaled each one in X before creating a Loft.

Regardless of the function settings, I got a thinner-than-paper result that I could not modify to get the same hollowed-out solid you got.

I know I could Offset the Polylines and 3D Subtract their Loft from the surrounding Loft, but I'm thinking there is something simpler I could do.

What am I missing here?

Jeff, I used the "Shell solid" tool to impart a thickness to the thinner-than-paper objects.

Henry, that was the first thing I tried.  It failed.

Oops... tried again with different values and found some that worked.

The direction based on the sign of the value didn't go as expected, but I can adapt.

Yeah, the tool can be flakey.

As demonstrated.  Still provides some nice capabilities, though.

Really nice, Henry.  The spring's my favourite of your flourishes, I couldn't approach your materials and textures either.

Thats awesome Henry. I never would have guessed that genie would permit changing profiles!
 
With the lofting aspects and when looking at your post # 10:
I presume that tcw does not object to lofting from the top part of the visegrip where the yellow loft is almost closed ( next to the adjustment knurled knob ) to further lofts profiles ( going down the view ) that are quite different in their respective profiles shapes, therefore what if anything needs to be done or is just as straight forward as the profiles suggest in the image?

It's pretty straightforward. The profiles at the almost-closed end are just circular arcs; all the others are Polylines each consisting of two line segments and a semicircular arc. Notice that this setup violates the rule that all profiles should have the same number of nodes. I wasn't sure how Genie would handle them, but I guess she appreciates their simplicity.
