"The ease of use and the presentation of the results are both awesome.
I have had ongoing interaction with the support team and
everyone is excellent!"

It is used for various civil and mechanical engineering courses and the students
love it. We are happy with the continuous updates to SkyCiv as well,
highly recommended.

"It was easily the most intuitive package available to learn; it is particularly easy to build the 3D model and define nodes, members, supports, materials, sections, then apply loads & combinations."
