Drawing software for steel structures contributes to automation of production process

The intuitive, user-friendly, efficient and flexible software Parabuild makes drawing detailed steel structures in 3D easy and fast for any user, even the less practiced draftsman. From this 3D model, the software automatically generates quality shop drawings, bills of materials, and DXF and DSTV files for production. New functionalities result in even more efficient production.

Drawing quickly and efficiently in 3D

Because steel structures consist of many parts, every effort was made to simplify and speed up 3D drawing. Connections are essential, which is why Parabuild includes a library of hundreds of standard connections that can be drawn with just a few clicks. Both connections and larger structures with multiple profiles, joints and arrays can be combined into one intelligent group - a macro. "Parabuild is the only software for steel construction that allows users to define any type of connection and all parametric macros themselves without having to program. Such joints and macros are drawn in template drawings, using geometric rules such as parallel, perpendicular, distances, .... Those templates can contain multiple macros and also arrays and can be reused for all projects. Even entire buildings can be created parametrically," clarified director Rudy Joris. "Moreover, to draw columns, beams and small parts quickly and easily, we have developed the Context Modeler. By moving the cursor, Parabuild suggests real-time logical solutions based on the cursor location, nearby profiles and other context, a very intuitive way of drawing. With Propagate, one click can automatically propagate a connection to other profiles in the drawing where that same connection applies. That saves time when there are many similar connections."

Automatically generate working drawings and other documentation

From this 3D model, Parabuild generates 2D detail drawings for parts and brands. Measurements and designations are added automatically and advanced machine learning algorithms ensure proper placement so that working drawings are clear and legible. This automation results in correct drawings and avoids errors. The 3D model can be used to create assembly plans such as anchor plans, side views, 3D views, sections and details. The software also generates other output such as bills of materials, IFC and KISS files.

Advanced CNC functionalities

In addition, the software fully automatically creates DXF and DSTV files for automated drilling, cutting and marking of parts. Automatic scribing is also possible, which eliminates manual measuring and etching/scratching and saves time. In the most current version, the functionalities for scribing were greatly improved. Contours of welded parts can be added completely, partially or via center points. If the part numbers of those welded parts are desired, the software automatically finds a suitable location for those designations. Each part with unique contours can also be assigned a different position number. This is very important for some MRP packages and complex marks.

"But we are going even further. Since the location of holes is very important, in the next version a line or point can be added on both the base element and the welded element in line with the holes. That way, the welder just has to make sure those markings are aligned," Joris points out. "If we have to scribe more, the marking module also has to work longer. In order to reduce production time losses, in the next version of the software one can choose the scribing settings for each situation: work with center points on the main profile and with lines on plates or place fewer or no contours for certain types of elements. Very many different filters are possible, allowing the user to choose which contours are needed for each unique situation and that is then applied automatically. We are aiming for the best of both worlds: fully automatic yet optimized."
