Section Builder
Build and calculate section properties for any shape using SkyCiv Section Builder! Build your sections using our templates, draw using points or line paths, or import a DXF file!
SkyCiv Section Builder Software calculates complex geometric parameters and performs stress analysis with an easy and intuitive online interface.
SkyCiv Structural Analysis and Design Software is completely cloud-based, allowing users to access their programs and files from a web browser from anywhere, anytime! No need to install or update the software.

PRODUCT FEATURES
What SkyCiv Section Builder Offers
Capabilities for modelling and analyzing simple and complex cross-sections.
Templates and Database Sections
Analyze sections from SkyCiv’s comprehensive library of 25,000+ standard shapes from the US, UK, Canada, Europe, Australia, New Zealand, India, China, Mexico, Singapore 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
Box Girder

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:
Combine shapes from our database library or standard shape templates to create built-up sections.
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.

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 the section and calculates buckling properties of cold-formed sections, including the critical buckling loads and 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.

Concrete Section Design
SkyCiv’s Concrete Section Designer (CSD) is powered by Section Builder and allows you to design complex reinforced concrete sections to ACI, EN, CSA, AS design codes and more!
Our CSD handles any concrete shape and reinforcement configuration. Calculate member flexure and compression capacity along with powerful 3D interaction diagrams.

Integration & Cloud Storage
Section Builder is fully integrated with SkyCiv S3D and SkyCiv Beam, allowing for custom sections to be directly used.
Sections can also be saved to the cloud for easy access across modules.
