Essentially prototyping some cannards and body pieces fo my track car.

You need to redraw the portion you need in Shapr.

Use construction plane to slice the car in multiple parts.

Redraw on the construction plane and use the cross section of the stl as a guide.

When your drawing is done you can loft it.
