01.3 - Video 2 - Advanced Modeling for Full Height Glass Partitions

Now this will be shorter than the last post I hope. I'll talk about how to model angled bracing but first the reason why I do it. Often the bracing isn't modelled as it is easier and faster not to model it and not to think about it, but when services coordination falls on your lap you'll be happy that you did model the bracing. When you receive drawings or a model(if you're lucky enough) from the mechanical engineers they have place the duct runs in various locations, its then part of an architectural technicians job to see that the ducts fit within the ceiling space and any other possible clashes, this is where the bracing comes in. Generally the contractor is given a typical 2D section of the full height glass partition detail that shows the bracing in that view only, on all the plans it is never usually indicated on what side of the wall the bracing is to go on. Without this coordination to make sure the bracing is not on the side that would conflict with mechanical ducts it is likely to hit you in the face(from experience), some contractors will just put it up the most convenient place at the time then later to find out there is problem. Below a diagram that shows you what you want to happen and what you don't want.





The best way to avoid this is to actually model the bracing or space holder for the bracing which will help you either indicate what side it is on in some sort of plan view or issue a model section or 3D of the area to communicate the potential problem to the contractor before they start putting up the frame work.


Now to revit, to do this i create 2 revit families a generic model family and a line based generic model family. These 2 families will nearly be identical with the reference planes, parameters that is in each of them. We first make the generic model family and then load it into the line base family, this is because in the line based family we are going to use an array and the number in the array will be a formula based result depending on the length parameter. To do this as one family you will have problems arraying the geometry as the geometry will try to stick to the reference it was modelled on.


See video for the tutorial for details.
