Design with Cold-Formed Steel, quickly and easily.
SkyCiv Structural 3D allows users to quickly and easily model their cold-formed steel structures, Z, C, Hat shapes from common international libraries and then perform design checks from AISI S100 and AS 4600 to complete the design process. Our design module also includes open step by step reporting as well as an optimizer which helps users test all sections in a particular library, to find the most efficient shape.
Developed by engineers. For engineers. Users of the SkyCiv suite drive the majority of changes and additions to the platform. SkyCiv software developers all come from a structural engineering background, with the majority being previously consulting structural engineers.
What's Possible?
Features that will accelerate your steel structure's design

Fully Customizable and Integrated Section Properties
Whether its a database shape from one of the various country databases or a custom built shape using a variety of preset shapes. The Section Builder will use a full FEA analysis to obtain the section properties of single material or composite sections. Have a section drawn as a DXF? Directly import that shape into Section Builder to analyze. All shapes used in the Section Builder are directly integratable with the SkyCiv analysis modules.

Full Featured Modeling Tools and FEA Analysis
SkyCiv Structural 3D is easy to pick up and use immediately -- don’t waste weeks of your time learning other software. The streamlined user interface gives you all the modeling power, without the headaches of congested toolbars or menus. Take advantage of the various modeling tools that make generating any type of structural cold formed steel (light gauge steel) model a breeze.
With SkyCiv’s FEA solver, run your structural model using the following analysis methods:
- Linear Static
- Buckling Analysis
- P-Delta Analysis
- Dynamic Frequency
- Response Spectrum

Integrated Design Module with Exportable and Detailed Design Reports
When your structural model is complete, import it and the analytical results directly into the Member Design module to run full design checks in accordance with a variety of design codes including:
Enforcing the same “ease-of-use” methodology, the Member Design module will walk you through any required inputs and display the results clearly and concisely. To further investigate any member, look at the individual member’s design report containing all of the hand calculations and other pertinent information, then export it as a PDF or HTML document. Use these reports as deliverables in your structural calc packages.

3rd-Party File Import Support
Get a headstart on your cold-formed steel (light gauge steel) model using the various supported 3rd-party file types such as:
- Revit (.RVT)
- .DWG
- .DXF
- .CSV
- Others in development!
With correctly formatted 3rd-party files, the majority of the modeling of your 3D steel structure can be completed, including material properties and section properties.
Full Calculation Reports!
SkyCiv believes in full transparency. SkyCiv offers full AISI and AS 4600 pdf reports, so you can view the AS 3600 worked solutions. Just clear, professional and powerful output. Click to see the sample reports of AISI PDF and AS 4600 PDF.
Intuitive Collaboration and Support
With the online connectivity of the SkyCiv platform, share project files with your engineering team for constant collaboration throughout the project. Take advantage of the Live Chat feature and share your project with the SkyCiv team directly to get immediate feedback like you haven’t with other structural engineering software.
With Version History, keep track of changes made to the structural model with annotated comments. If errors are made, revert your model to any previously saved version. Monitor issues associated with projects using 3rd party apps like Microsoft Teams and Slack.

Want Automated Functionality?
Are you a structural engineering business leader looking for automated analysis or design functionality that can drastically help your business? Are you currently a structural engineer that is familiar with JavaScript? Our API customers are reaping the benefits of an underappreciated technology in the structural engineering industry. If this sounds interesting to you, inquire about the use of the SkyCiv API, which supports the majority of functions available through the platform version of the SkyCiv suite.
