Viewers question regarding help to trace a photo into FreeCAD that has curved edges. We learn the "rule of three" for tracing with B-Splines and ways of using mirrors and symmetry to speed up your tracing. We first trace the outer of the model using bsplines and use mirror to mirror the corners across the axis to save us time and merge the sketches together. We then pad the part and apply a thickness to hollow out the part using the part design. We then trace the inner part using b splines and use the geometry tools to create a symmetry across the center line. We tackles one corner with a fillet and attach the resulting sketch to the bottom of the hollowed out object before padding. We finish with a few pockets for the mounting holes.
