I can’t recommend strongly enough, Shape Builder, from IES software for calculating section properties. I work for a Curtain Wall Sub-Contractor and we design custom aluminum sections all the time. Shape Builder lets you import dxf files very easily, even very odd shaped profiles and will then calculate all the section properties for you.
