Hi

How can I bend this spring, following the black curve

Thanks again

Make a straight reference curve for your spring, then make the curve line you want it to deform to
Select your spring, then use the deform flow command, select the straight reference curve first and then the curved one

This does deform the profile as you can see. If you want to make the spring profile constant then deform your helix first before you sweep the cross section to create the spring

You can also use Surf --- Surf for the Flow function...



Of course it's big deformed here because target surface has not same length/width size! ;)

Thank you Grendel

Thank you PILOU,

but I prefer that you deform it

It's deformed (an arc surface against a flat line surface! ;)

And of course you can give any form at the target ribbon surface!

WOW...this is good to know. I never did understand the deform tool. We need more postings like this on using some of the more advanced tools.

I've always had hit or miss with the network tool. Some times it works other times after an hour or so of fiddling I simply give up.

Normally result is quasi instantaneous ...if not curves are not well positionned between them ! ;)

Else Flow is terrific for project deform any volume on any other one! :)

A cool use of the Network function... as direct modeling! :)

Of course you can use it on a more elaborated "Volume"! (with the other modes following positions of curves! )
Here just a simple surface! :)

To me, the NETWORK and DEFORM tools are what truly make Moi3D stand out from the crowd.

This kind of organic shape is actually pretty easy to model in Moi3D—perfect for jewelry design!
