How did our predictions seven years ago for Building Information Modeling fair? Let’s take a look back seven years to 2009, when the concept BIM had become common parlance in the AEC community, and see if and where we’ve fallen short of, met, or exceeded expectations for our beloved BIM. How you define the acronym BIM depends on when the one claims BIM came into being. According to WikipediA, BIM was first used in papers in the mid-1980s, and the term 'Building Information Model' first appeared in a 1992 paper by G.A. van Nederveen and F. P. Tolman.[7] However, the terms 'Building Information Model' and 'Building Information Modeling' (including the acronym "BIM") did not become popularly used until some 10 years later. In 2002, Autodesk released a white paper entitled "Building Information Modeling,"[8] and other software vendors also started to assert their involvement in the field.[9] [1] For the purposes of this essay, I will pick it up in June 2007 which is when I started working at Autodesk as an MEP Technical Specialist. In 2007, BIM was the buzzword at ...

In the past I have had to help several clients clean-up, break-up, and troubleshoot Revit models. With my focus being on RMEP, this entry will be from that point of view. Breakup by DisciplineThe process to break up a Revit model is about the opposite as to what we would do in AutoCAD. AutoCAD has a WBLOCK command; Revit does not.  So, take any RMEP model, we will call it ABC_RMEP.RVT, that contains all disciplines. Open the model, SaveAS, for example: ABC_PLUMBING. Now the fun begins. I will make a 3D view and then using the Visibility Graphics, I will turn off all the objects related to Plumbing. You may ask now, what about pipe? Depends, do you want to have only the Plumbing Pipe in the Plumbing model? If so, then use a FILTER that will sort out the Plumbing Pipe, leaving the Mechanical/Hydronic Pipe “on” for selection/deletion. Once the other disciplines have been deleted, issue the PURGE command and selectively remove anything that isn’t Plumbing in nature. Save the file again. Lather, rinse, repeat for the remaining disciplines.Once all the discipline specific files ...

This happens ALL the time with new students. At some point during my class, a student will comment about the Home tab and most of the tools on the Home tab as being unavailable or greyed out. This literally happens with every new class.Revit does this on purpose. The reason this happens is because you are in the middle of another command which places you in edit mode or what we use to call sketch mode. I tell students to look at the upper right corner of their ribbon and if they see a colored tab, they need to select that tab and make it active. Once a student realizes this, they have to either finish edit mode by selecting the green check or cancel edit mode by selecting the red X.Mark Petrucci

Not too many users are aware that in Revit MEP schedules can be embedded into other schedules.  This feature is only available in Revit MEP and not in Revit Architecture.  And, it is only available in certain types of Revit MEP schedules.  Embedded schedules can be inside of Room and Space schedules and System schedules (Pipe Systems, Duct Systems and Electrical Circuits).This feature will allow you to create a schedule inside of another schedule.  This could be used if you want to list what fixtures are in a space, or what pipes are in a system, or what devices are on a circuit. To create an Embedded Schedule, you begin by creating a Room or Space or System schedule as you typically would.  You can add the fields desired, configure the sorting method, modify the formatting.  In the Schedule Properties dialog, there is a new tab at the end for Embedded Schedule. Here you can select what type of schedule you would like to be embedded and then you can select Embedded Schedule Properties, to modify the properties of ...

I have had several clients mention that they could not find the command buttons for the functions: Parallel Pipe and Parallel Conduit. The easiest way I have found to get the buttons back is to learn the keyboard shortcuts for each command, where upon, once used the buttons themselves seem to magically reappear in the ribbon. The keyboard shortcuts are PE for Parallel Pipe and PO for Parallel Conduit.
