New to Shapr3D but I was wondering if there’s a way to get the body to adapt when you change the sketch he is related to? Let’s say I do a 500mm plate then switch to 700 later on, I’d love to get my body to adapt.

Also do you think to implent parameters or a way to calculate fraction of a piece, exemple when you want to get a dado at 1/4 distance from the edge.

Thanks

To answer your first question… no. The body is not tied to the sketch that it was created from. You simply change the body using Offset Face or Extrude or Move or another appropriate modeling tool.

Unfortunately the answer to your second question is also No.

Just to let a drop here: Parameters/Variables and calculations/formulas would be really awesome!
