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.

Stuart Agars

Managing Director of Struct-Sure Limited

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.
