Konstru translates Openings across platforms but what do we mean when we talk about Openings? Revit for example knows two types of Openings: Shafts and Opening Cuts:
- Shafts are Volumetric Elements cutting through others. That's what we call Openings in Konstru.
- Opening Cuts are hosted Openings on a specific element, we consider them part of the element, this means we are exporting the floor with a hole.
After uploading the model above will look like this:
Each floor geometry contains a hole on the right, those are the opening cuts belonging to the floor. The opening shaft won't be visible but you can see it in the element list.
Revit, Excel and Grasshopper also support the idea of shafts (un-hosted openings).
All other platforms do not support shaft openings. For these, Konstru automatically calculates, and creates profile curves with floor openings. So, a model with shafts created in Revit will still have floor openings in Etabs, Tekla, RAM or SAP. When going back from a non-shaft platform into Konstru, Konstru automatically calculates and creates openings.
In Grasshopper you'll end up with the same representation as you see in the web viewer. Openings cut out on the right side of the slab, but not on the left. To get your shaft openings you'll have to extrude the opening element and subtract it from floors extrusions. This way your openings will show up correctly.
