CIM Development: X. Framing and Beam Systems Follow

On some occasions, the desired scope might be there but in too much detail. So, you need to keep the scope but in a "simplified" form. Such cases include framing and beam systems that include dozens of elements but are usually installed in zones, bunches.

While simplifying the model, we need to make sure we hide the small detail items like nuts and bolts. These add up to the number of elements and also contribute to the mesh analyzing, which increases the upload time. This may also not be useful for the required schedule. (Image 1)

In addition, you to this also make sure you remove an additional level of details from the family. This would help reduce the number of polygons and the file size.

Besides removing or hiding small unnecessary elements, it's also recommended to simplify the geometry of elements, such as converting bent profiles to rectangular ones. This will decrease the number of polygons and will make the upload process faster. (Image 2)

Imagine the same big building as above. That building has concrete foundations but a steel frame (columns & beams). Framing installation would follow the slab zoning (Image 3). Therefore, instead of grouping numerous beam elements together in ALICE, you can “replace” those beam elements with a placeholder element - here the yellow slab - that matches your erection strategy.
