Compare performance in Fusion 360 - avoid complex sketches.

When working in the CAD/CAM application Autodesk Fusion 360, keep in mind - even more than in other parametric 3D modelers: always keep as simple sketches as possible and model any geometric features later in 3D!

Efficiency and resulting performance of the model can be strongly dependent on a correct modeling procedure - and the more complex the final design, the more apparent will any erroneous procedures become.

Let's show the differences on a relatively simple model of a comb (array of 25x25 spikes). How will be its performance influenced by two variants of modeling procedure - creating the spike array in a sketch, or arraying the resulting 3D model. Compare:
