Hi Shapr Community!

I’m trying to create a conch like shell form in shapr3d but I can’t figure out how to revolve the shape into a taper. Does anyone know how to create this?

Please help!

Best,  
Peter

I got a lot of help on this type of thing from this thread:

> Hi! Brand new here, and fairly new to Shapr3D. I’m trying to make a tapered spiral. I’m trying to recreate a chameleon’s tail shape. I’ll include pics below. I got as far as revolving a circle around axis to the amount of revolutions and length, but when I went to scale or change one of the ending circle profiles, it didn’t work… any way on how to achieve the chameleon tail? I’ll include pics below. Thank you.
