Cloud-based Structural Analysis and Design Software
SkyCiv Structural 3D is our most powerful online structural analysis software, offering a full suite of modelling, Finite Element Analysis (FEA) and design capabilities.
This 3D frame analysis software allows you to model, analyze, and design steel, timber, concrete and general structures. The 100% cloud-based engineering software allows users to access their programs and files from a web browser, anywhere, anytime!
No installation is required and updates are automatic so everyone is working on the latest version of the software. Structural 3D has an intuitive user interface which allows for rapid creation of complex structural models.

- Perform operations such as rotate, mirror, translate, cutout, and more.
- Calculate complex geometric properties such as moment of inertia, centroid, shear, section moduli, torsion and warping using powerful FEA.
- Perform analysis on your sections to calculate stress values


An Effortless User Interface
SkyCiv's mission is to make complex engineering tasks simple and intuitive. This starts with a user-centric interface. We have a range of features designed to make using Structural 3D a breeze:
- Create models using our intuitive pen tool or Excel-like datasheet entry.
- Import models from Revit, Grasshopper, DXF, IFC and other structural modeling software.
- Access range of right-click and operation functions, such as splitting members, copy-paste, multi-edit, intersecting members, area load functionality, and more.
- Simple input fields with detailed info tips and links to video tutorials.
- Create vertical and horizontal gridlines to accelerate modeling.

Make the Switch to SkyCiv

"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."
