Default Table Leg

I was recently challanged or I should say after talking with Mike Mezilack at the Aspire Camp I found a modeling challenge. So here it is. If you do a standard two rail sweep you find that the bottom of the arch will be flattend out. The solution is to run a negative arch using the side profiles then run another two rail sweep using straight rails and one of the profile legs. Group all the components then bake and cut away the excess.

This is only made to show proof of concept and is not intended to be used with a table.

I hope you made it home safely. It it took the whole 6 hours to figure this out.

There are still a few issues. I get a lot of spiking around the edges because the leg seems to shrink about .002 when combining the two modes. And I think the over all height is a little high and doesn't match the diameter of the leg. I can't just lower it because I believe the deference comes from the base height.

I would slice it away but that seems to be to much calculating.

It's funny but the one thing I made a mental note to remember was the multiply mode and how to remove those edge spikes. But I thought that was combined with another multiple mode.

Jim, have you tried that leg design in Rhino? Draw the vector and rotate it 360 degrees and you're done. About 5 minute design, and very sharp (all NURBS).

I'm just starting to experiment around with MADCam (got the post processor from Mark Meyer), so I can toolpath from Rhino. Waiting for the 4th axis post processor, because that is where I really think Rhino and MADCam will shine.

Thanks Russ,

This was just a challenge for Aspire. I'm sure this type of modeling would be better suited for a different program.

I get really bullheaded sometimes, okay most of the time and just need to prove thing to myself. I just need to learn when to let things go but when I do that I will stop learning.

Got it! Aspire.

How about this. Just do a single two rail sweep with a half circle vector, scaling cross section with width. Even easier than I could do it in Rhino.

Jim,
Do you intent to cut the leg on the table or on the recoil?

Russ that's too funny, I got so rapped up into making a negative extrusion that I put legs on the round shape. When you do that the shape comes out flat at the bottom. I didn't think is was supposed to come out that way. I thought it should have come out round. I didn't even think to take the supporting legs away.

Thanks for the help.

Mick,

I'm sorry I didn't catch your post. This was only an exercise in modeling I don't intend to cut it.
