Hi all,  
New to Shapr3D and CAD. Excited to be exploring and creating my own creations! I am hoping there’s an easy way to do this.

I am using the iPad app.

Need to transition from a shape in sketch to another in concentric circular pattern, my case I need to keep the lines pretty close together, as I want to 3D print this as a “telescoping” shape. I was using Offset Edge, is there a way to do this, like how you can loft easily between shapes/bodies, but with sketches? And separate shapes vs a smooth shape w loft.

In my example, I am starting with a head shape and want to transition over 20 lines or so, into the circle shape around the outside.

External vector program will likely needed that has a blend tool then import as DXF.

Thanks for replying. Do you have a good one in mind? Affinity designer?

Was also thinking, could I use a loft and somehow chop it up into segments and voila there’s my transformed shapes all chopped up from a solid loft. Curious to know if you all have seen that used.

Many thanks again!

Loft the shapes and split the bodies for amount of layers you need.

Oh Inskape and Illustrator has the Vector Blend tool. Affinity Designer doesn’t
