The Fabrication feature set in Revit is an example of that continuous incremental improvement. We all want to see a more direct translation of our effort into the actual building components. In October Autodesk announced the purchase of MAP Software, taking a big stride toward that goal of direct translation to fabrication data. However, much of my previous review was spent pointing out how far they still needed to go. Here is the short list of functionality that I still expect in order to consider the fabrication features complete inside of Revit: Maintaining the Revit style of modeling Full engineering support The same ease of documentation The ability to create a complete model Spool drawings Direct export to fabrication equipment Support for robotic field layout Just as before, this is my personal review of the fabrication software within Revit.
As you can see from the many available demo videos of the new fabrication features in Revit for example https: The modeling method for standard Revit MEP elements is strongly based on the straights, allowing the system family settings to insert transitions and bends for you.
The new fabrication features default to specifically picking and placing all components. As I said, this is not the only way, just the most obvious. For instance, here is the process to create a run of duct aligned to another run 15 feet long, reduce its size, run 3 more feet, turn and run another 15 feet. This list includes every required action See Figure 1. Figure 1: These have received significant updates for Fab parts in the release.
Trim and Extend now work—with the caveat that they only work from one Fab part to another. This means that you can extend a MEP Fabrication round duct to meet a MEP Fabrication rectangular duct and it will connect and place the tap fitting between the two, as shown in Figure 2.
However, you cannot use these modify tools with anything else in the Revit platform. You cannot extend a duct to meet a detail line or a reference plane. Similarly you cannot drag the endpoint of a duct and have it snap to a detail line, though oddly, you can drag and snap to a reference plane. Figure 2: Editing tool - Extend There is also no remote snapping function for Fabrication parts aligning with distant model elements as you drag them around; this includes even aligning with other distant Fabrication parts.
Not only are the Modify tools only partially functional, but such simple and common modification methods as changing a size or turning an elbow into a tee are not supported at all. In Figure 3 note the lack of the small plus symbol for the Fab part on the right-hand side. This means that even small changes or additions first require deleting large sections of your work and redrawing.
Figure 3: After making minor moves, nudging a duct or pipe around, it is easy to select a large run of straights and fittings then hit the Optimize Lengths button. Full Engineering Support There is no change to this for ; MEP Fabrication parts still do not support the calculation and propagation of flow in a duct or pipe or the assignment of the system type.
Systems and flow are a bit finicky and require effort to maintain in standard Revit duct and pipe layouts, but they do indeed work. This would still allow you to perform airflow calculations with Revit spaces with no change from the Fabrication features.
As mentioned before, the flow defined by the Air Terminal will not propagate in the Fabrication part duct run. Ease of Documentation Full engineering and construction documentation can be genuinely beautiful when generated from Revit. Model elements and annotation elements blend well and all of this can be done much easier and more quickly than what I remember from my now distant AutoCAD days. Is this ease of documentation still available with Fabrication parts? Mostly yes.
Updated for there are significant improvements in the ability to display and document your project. To illustrate, the hidden line functionality was similar to using all Generic Models categories. In it works just as desired—fab parts located vertically below other fab parts even below standard Revit MEP elements are properly broken with the dashed line type below see Figure 4. This even includes the proper display of insulation! Figure 4: Accurate hidden line display As mentioned earlier, systems and flow do not exist for Fabrication parts; both of these are frequently part of my documentation.
This is a limitation both for design and documentation. One unexpectedly missing documentation feature is single line display. For Revit duct, setting the view to Detail Level: Coarse will turn it to single line, both Medium and Coarse show pipe as single line. This is often useful for particularly small scale plans. However, this cannot be done for MEP Fabrication duct or pipe parts. A Complete Model? When talking about Revit, one of the more common statements is that the key to success is good content.
Even though in the first release of Fabrication in Revit, there did seem to be plenty of content to use. However, if there are some minor modifications needed, there is no fabrication configuration editor. You can download the default configuration from Autodesk or receive a configuration from a current CADmep user. For instance, if you want to change the default cast iron no-hub elbow from quarter bend to short sweep, there is no way to do this within the Revit interface.
One of most useful things in Revit is the family editor—both stand alone and in the context of a project for in-place families. There are times when the parts needed are completely custom. Imagine a duct fitting that can only be built by hand in the corner of the shop by the old school tin knocker.
This fitting may not be in the pre-created list of Fab parts. Fabrication Parts are not Revit families, which significantly limits their customizability.
Spool Drawings There is no change to this functionality in Usually it represents a handful of parts that are going to be assembled in the shop and shipped to the job site. This might be a pre-assembled handful of duct fittings or welded pipe and fittings see Figure 5.
Figure 5: Assemblies as spool drawings Some information about Fabrication parts is not available for use in Revit schedules i. This will again require additional care with regard to coordinating between information-rich sources such as the exported fabrication file. New for , this is automatically installed, but it shows up under the Add-Ins ribbon instead of the Systems tab, being obviously related to any of the other Fabrication functions. What about in-direct exports? Many installing contractors own their own fabrication equipment, but others buy fabricated parts from multiple sources.
The best way to do this may be with the same. The lowest common denominator is a simple list of parts with enough data to get the correct size and shape.
As mentioned above under Spool Drawings, this data is lacking the required fields available to be scheduled with Revit Fabrication parts. Support for Robotic Field Layout Again, there is no change to this functionality in Using a robotic field layout tool is the best way to translate your carefully BIM coordinated layout to actual locations in the building. As already covered, Fabrication Parts are not Revit families. This being the case, some other more manual method of identifying and exporting hanger locations will have to be devised.
Figure 6: However, when it comes to fabrication, they are instead using the previous AutoCAD-based. Competition between the players helps drive the whole industry forward, and I will continue to watch the sometimes gradual and sometimes transformative steps in this area of our industry with tremendous interest.
To use the Design to Fabrication feature, model a run of duct or pipe conduit and cable tray not supported and click the Design to Fabrication button. This means that for the numbered lists above, if you used this conversion feature, you can create the run of duct with Revit system families, and convert to Fab parts with a single click.
To use the Route and Fill feature, select a fabrication part with an open end, click the Route and Fill button, then select any other compatible fabrication part, also with an open end. The tool is very intelligent and offers multiple routing options that can be scrolled through—or even better, select the checkbox to choose the specific fittings desired.
