Most of the time exporting an object out of a cad program the topology will look ugly and needs a lot of cleaning.
But there is a way to help you a little bit in the cleaning process and that's the use of Isoparam edges in Plasticity.
I don't know about other CAD programs but probably there is a way to add those edges in Fusion 360 or MOI3D as well.
Adding edges around details, helps you to have better topology and keep those triangles go all over the place and terminate them where you want.
Hope this little tip makes your optimization easier.
Top without isoparam, bottom with isoparam.
