Parabuild runs on both AutoCAD and BricsCAD platforms. Structural steel objects can be modified through the standard AutoCAD and BricsCAD commands or using the Object Property Manager.

All Parabuild objects are integrated as if they are native AutoCAD/BricsCAD objects.

Fast and intuitive modeling

For easy detailing of structural steel - small parts or frame elements such as beams, columns, girders, struts, joists, purlins - use the Context Modeler for maximum productivity. Move the cursor around and solutions are offered in real time based on cursor location, nearby members and other context. The new element is automatically linked to the nearby members or to the grid.


Parabuild has a library of hundreds of standard steel connections. Detailing connections is easy; select the members and only valid types are proposed for that situation. The connection is immediately drawn and any changes made are shown instantly on the 3D model. Easily turn unconnected members into fully connected structural steel.

User-defined connections

Every single standard connection was created using tools that are available to any detailer, without programming a single line of code. This was done by using simple geometric rules on members and parts inside template drawings, which means you can create your own connections! They are integrated with the existing connection system for easy re-use in all your projects.

Geometric constraints

Parabuild is the only structural steel detailing software that allows fully constrained structures. Connections and macros can be constrained in template drawings and re-used in any project. That includes whole structures, trusses, wind bracing, cladding, stairs, … This means it is possible to customize Parabuild without hiring a programmer or writing any code.

Clash detection

Parabuild will automatically detect any collision between parts and show it on the screen. Bolt clearance and hole to edge/hole to hole distances are checked as well.

Numbering of identical parts

Parabuild automatically recognizes identical parts in the model, with the purpose of making the Bill of Materials shorter and for needing less shop drawings.

CNC file generation

Parabuild can write DXF, Dstv, Sat and Step files automatically for the purpose of using them for CNC machines.

Shop drawing generation

Parabuild will generate clear and readable shop drawings for the fabrication of all the parts in the drawing.

It supports 'Position' drawings, which are 'per part' drawings containing dimensions for holes and cuts.

It also support assembly drawings, which contain the dimensions for welding multiple single parts.

General Arrangement Drawings

Parabuild has many tools that allow you to quickly create GA drawings. It will also help with updating the existing GA drawings after changes have been made to the 3D model.
