I am fairly new to Shapr3d and I am having difficulty envisioning how to make a 3D model of a shoe insole similar to what is shown in the photo. Since it has multiple curves I don’t know if I should state out with an extruded rectangle and Subtract into it with Sweeps or Lofts, or if I start out with separate drawings using Sweeps and Lofts and then Union everything together. The insole needs to be the same thickness but I don’t know if there is a way to use the Shell command to make this.
I have been able to make some complex designs so far, but this one confuses me so some suggestions would be welcomed.
