Standard templates and database of sections
Analyze sections from SkyCiv's comprehensive library of over 15,000 standard shapes from the US, UK, Canada, Europe, Australia, India, China, Mexico and South Africa.
Or build your own shape using our templates:
- Rectangular/Square
- Hollow Rectangular/Square
- Hollow Circular/Circular
- I-beam
- T-beam
- L-beam (Angle)
- Double Angle
- Channel
- Double Channel
- Triangular
- Hollow Triangular
- Box Girder
- Multiple Cold Rolled Shapes
- Change dimensions via the form or dimension lines
Custom Shapes and CAD Import
Need to model a shape not available in our templates? Specify your own custom shapes:
- Points Shape: Define points and create your own polygons.
- Line Shape: Define a line path and create a polygon with a thickness and radius.
- DXF Import: Prefer to sketch in CAD first? Simply import your DXF file into SkyCiv's Section Builder for analysis.
- Union, Intersection and Snap to Grid features to accelerate your section modeling process.


Built-up Sections
Model your built-up section by adding multiple shapes:
- Add shapes from one of our many templates.
- Use operations including rotation, translation, and mirroring to specify relative positioning.
- Calculate geometric, bending, shear, and torsion properties.
- Utilize meshing and FEA to solve torsion constant and warping constant.
Composite Sections
Need to model sections made up of different materials? We have you covered:
- Assign different materials to individual shapes.
- Calculate section properties via the Transformed Section Method.
- Original section properties are also presented in comparison.
- Easily model laminar beams and other built-up sections made up of different materials.


Concrete Section Design
SkyCiv's General Section Designer plugin allows you to design complex reinforced concrete sections to ACI, EN, CSA, AS design codes and more!
Our general section designer handles any concrete shape and reinforcement configuration. Calculate member flexure and compression capacity along with powerful 3D interaction diagrams.
Cross Sectional Analysis Using FEA
SkyCiv cross section builder software enables you to perform analysis on custom and template cross-sections to calculate bending, axial, torsional, and shear stresses. This feature allows for the application of forces to your sections, providing quick stress results using our powerful FEA engine.
Users can easily review axial, bending, shear and torsion stress results via colored contours and PDF reporting. The cross sectional analysis, combined with powerful modeling, lets you design complex and custom shapes with ease.


FSM Calculations
The Section Builder Software has an integrated Finite Strip Method (FSM) Calculator, that meshes and runs a finite strip method calculation to obtain the factors required for an appropriate Direct Strength Method (DSM) design.
These factors are supported in our design modules for AISI (2016) and AS 4600 (2018) to ensure users can run their DSM designs from start to finish.

"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."
