BricsCAD BIM: The ‘Geometry First!’ Idea

Geometry First?

I was wandering the streets of Brugge with Hans De Backer, the head of software development for BricsCAD core. As we are both senior geeks, it goes without saying that he and I were talking about the Bricsys approach to BIM. I’ve (really) been pondering a document (for a really long time, says Sander) that outlines our approach to BIM; one that explains what makes us different from everybody else. Since Hans is so familiar with BricsCAD, I knew that he could help me build the story.

A few weeks earlier, Pieter Clarysse, product development manager for BricsCAD BIM, came up with the idea of “Real 3D” as an end-to-end description of the BricsCAD BIM workflow. Start conceptual design, freely, in 100% 3D solids. After you get project approval, then add building data incrementally to make the BIM intelligent. Then, automate the creation of sheet sets for construction documentation and billables.

Pieter’s idea of Real 3D was a real differentiator. Hans took it one step further and we had our rallying cry.

Geometry First!

Here’s how Hans described the benefits of Geometry First:

BricsCAD BIM and BricsCAD Shape (our free, 3D solid concept modeler) both provide complete 3D modeling freedom for every type of building component. You can create designs freely and modify them deeply, using 3D solids. Building components are not restricted to be predefined shapes, as in most architectural design products. Instead, BricsCAD BIM uses computer-learning and machine intelligence to analyze the solids selected for each modelling operation. As an example, consider the BIMDRAG tool. BIMDRAG provides intelligent behavior when, for example, moving a floor. Walls that have a top or bottom face touching the moving floor slab will “come along”, as you would expect, when you move the slab.”

Machine intelligence == simplicity & flexibility

“No dedicated connections between these walls or floors are required to achieve this, nor is there the need for the user to define them. Instead, intended connections are detected and preserved, or repeated. What makes tools like BIMDRAG different from the ‘move’ command is that adjacent solids are also analyzed. Then, the drag (move) operation will be performed ‘as expected in a BIM context’.”

“This also means that behavior of BIMDRAG will change when dragging the vertical end face of a wall, compared to dragging the top face of said wall. It’s the easiest way to model a building concept freely. It also keeps the next step in the BIM workflow in mind – connecting your concept model to the database – the ‘I’ in BIM.”

BIM: all in solids, all inside one workflow – Geometry First!

The first two key differentiators for BricsCAD BIM are ‘Real 3D’ and ‘Geometry First!’. Start with these, and BricsCAD BIM can take you from design concept through construction documentation, all in one workflow.

We’ve been saying that our approach to BIM is “designer-centric” for a while. With the introduction of BricsCAD Shape, we’ve made it much easier to focus on your design, with a super-simple user interface. The CAD accuracy of real 3D solids from the start, stored in DWG files and 100% ready for BIM – with zero re-modeling required.

You can turn your client-approved 3D model directly into a BIM, by just opening the DWG file in BricsCAD BIM. Next, run the BIMIFY tool, and you’ll be a week ahead of the other guys in just minutes.  We’re Bricsys and we’re starting a BIM Revolution. Stay tuned for more information about the Bricsys approach to BIM.

  • Another take on this is to note that the BIM product sits over our Platinum mechanical tools and can also work with Sheet Metal. The architect may use sheet metal, lofted surfaces, deformed surfaces and every other modelling tool we have. The Architect rules!
