Revit 2013/AutoCAD MEP 2013 IFC Improvements

This post is part of an AU class this year, MP1465, Supercharge Your AutoCAD® MEP 2013. It came up as we started working with outside vendors that are solid AutoCAD MEP users, but not Revit users - and that's what we're using.

First up, know the rules:
- Architecture and Structure items convert pretty nicely, with ACAD Arch walls converting to Revit walls. You may need to swap some styles, check justifications, etc. but getting the overall model works pretty well.
- MEP objects come into Revit from ACAD MEP as in-place families, but if you setup your import options, and have your classification definitions assigned to MEP objects in ACAD MEP, then they come in as "pipes, pipe fittings, duct, etc.". Be aware - they don't have the same behavior as a duct, pipe, etc. that was created with native Revit tools. But you can add connectors as needed to make these types of connections.

Here's the excerpt from the class (or as I like to call it, the "tease")...

IFC stands for Industry Foundation Class, and it’s a file format that is universally shared between CAD platforms. The intent is that an object in a program like AutoCAD MEP can be converted into the same type of object in Revit, or other BIM applications.

In order for an object to be exported to IFC, it has to have an object classification assigned. To look at the default styles go to ProgramData\Autodesk\MEP 2013\enu\Styles directory and open the IfcShareBldgElements (MEP).dwg file.
 
In the style manager, look at the classification definitions under Multi-purpose objects. IFC properties can be assigned to these objects:

 


Once the items are selected, the classifications tab lists the information associated with an MEP object that will be exported:
 
To use these in a file, and assign them to MEP objects, you have to copy them into your current drawing. Use copy and paste in the style manager to add both classification definitions to the current drawing.
Select OK to exit the style manager. Now that they’re in the drawing, you can edit the properties of objects to assign the classification. I’ll grab the ductwork, and then go to the properties palette:
For most other parts, IFC Type Classifications are mapped to MvPart Objects (such as equipment, panels, and devices) automatically. This classification is added in the Autodesk Catalog Editor by default. You can modify this classification or add more classifications to the content library in the Autodesk Catalog Editor.

Once you’ve added the correct classifications to MEP objects, review the IFC export settings. From the application menu, select the Export tool, and then select IFC. The options are located on the export dialog, and the object tab lists all objects that loaded into a drawing – you can choose to add or remove objects as needed.
After you review the options, you can run the export. The IFC file is created in the project folder. To test this, I’m going to open the file in Revit. Before doing this, open the IFC Import options on the Application menu, under Open:
Before importing an IFC file, you need to go through and map IFC class names to Categories and sub-categories. This tells the MEP object what is used to control its display in Revit.
Once the IFC file is imported, it will appear something like this:
The imported objects take on most of the characteristics of the equivalent objects in Revit. You may need to check IFC mappings in both the AutoCAD MEP file and the Revit file during this process, but this represents a major leap in compatibility between the applications.
Be aware that imported objects may not completely take on the behavior of a normal duct. For example, the duct is treat like a duct with properties assigned, but it does not include the connection, system or sizing behavior. You have to add a connector to attach duct to it.
I don’t care what anybody says…this is really cool…
Happy BIM'ing - see you in Vegas!




zzzz....uh...huh? AU is in a week? Geez, I overslept..

Wow, where does the time go? Autodesk University (#au2012) starts classes one week from today...and the last couple of months have been crazy, getting all of the handouts, datasets, powerpoints, props, home movies, etc. finished. But I'm about there...

And when you finally get a moment to reflect, you hope you've put something together that really hits home with users. This year's approach was a little different - I wanted to find what the really obscure little things were that come up as support issues, and get them addressed. But I also needed to hit on the bigger picture, and make sure that the day to day items - using systems, making families quickly from scratch, or from manufacturer's content, etc.

And then I an email from an engineer I know, saying that he doesn't think MEP BIM is ready for primetime yet. And I couldn't disagree more, but if you don't train your staff for a few years, then, yeah - you're likely to have the same attitude. So here's what I think - Revit MEP 2013 and AutoCAD MEP 2013 represent the best two MEP design applications on the market, hands down. Both have their strengths, but both require you to make some changes to your design process.

Here's an example. In one of my classes, we talk about adding an instrument connection to a duct or pipe. The instinct says, add a tap. Instead, if we're making this connection at a fitting, such as a duct tee or flowmeter, why not add the physical connection to that component? It will stay connected to the part, if the part moves or changes size, the connection is still there. It can be fabricated into the part prior to being added in the field, so that may save a little "field fit and finish" time.

That's one of the challenges that comes with BIM. If you're still in the drafting mentality, then all you're thinking about is a line or circle - but in BIM, you HAVE to think more from a DESIGN standpoint. It's all about making a more easily constructable building, that's more sustainable while allowing for creativity in the design.

The beauty of AU is that it's a gathering of like minds, that are looking for that tip, or method, that helps you stay current with technology, or gain that competitive advantage. We're driven to find better ways to leverage our tools, and make life easier for ourselves (as though it isn't already). And we really want to find ways to interconnect all of this information, and come up with the big picture, that satisfies the client's and end users needs (think airport electrical outlets).

So take a little time this week - network with your peers, get to know some of the industry leaders, and take advantage of some of the best and most passionate instructors in the world. We'll all be hanging out in the same place - so come by, say hello, and let's talk about the future. And if you can't make it, check our AU Virtual - last year, tens of thousands did - so the learning doesn't stop on November 30th. I'm ready - are you?

See you in Vegas!

A few shameless plugs...for AU 2012!

I gotta love our marketing people...they've really been grabbing on to social media and getting ourselves known for being thought leaders in the BIM arena.

So they put together a little highlight reel for the classes I'm teaching at AU this year, showing a few of the projects we've worked on in Revit, along with a few pics from previous classes...check it out!




Here's the list of classes I'm doing this year - in case you missed it:

Small Groups, Large Groups, Red Crowd, Blue Crowd… AU Conference Presentation and Teaching Tips


Now that I know I’m headed back to Las Vegas for Autodesk University this year, it’s time to pass off some ideas about how to have a successful class. Whether you’re a first timer or an old dawg, you’ve got to understand that presenting at a conference isn’t the same as a regular training class, or presenting to your buddies in the office. So let’s start with a few things that help your classes get high marks.

1.       Know Your Audience

If you’re a beginner, intermediate or advanced instructor, this is the most common mistake. Don’t teach symbiotic quantum physics to first year AutoCAD users…and it may sound silly, but keep it simple. You’re not there to impress them with your prowess or command of the English language. You’re there to communicate ideas, instill excitement and passion, and motivate the learner.

The AU crowd, for example is a little different. They’re a highly technical bunch, but they also are in Vegas…yes, Vegas has them now. And in most cases, they have a fairly good understanding of how the tools they’re using work, but are looking for the gems and tips they can’t find in the books or help file. When they signed up for classes, they were looking at your description and skill levels. So whatever you’re teaching, you need to stay in that general playground.

The key is to make sure your topic is something that is valuable to them. Cruise the discussion groups, talk to coworkers and check out the blogs to see what people are looking for. Since you’ve already submitted your class, make sure you tune it as needed so the information is relevant. Even if it’s advanced class, you’ll always get a few lost souls that probably didn’t mean to sign up for your class, but could really benefit from the topic.
                                                                                                                                                       
Know the Audience, Part 2

If you’re presenting for a first time, it can be daunting. I was so nervous in my first AU class, I kept tripping over the screen stand legs, which unfortunately stuck out about 3 feet in front of the screen (appropriately the class was about interference conditions in AutoCAD MEP). Get out and literally get to know your audience. If all you do is stand in front of the podium, your first contact occurs when you begin to speak. I like to walk around the room, introduce myself, talk to the users, even meet some outside the door (I’ve also been known to take tickets and charge admission…oops, probably shouldn't have said that). Ever notice how it’s easier to talk to friends than a large crowd?

This requires that you make sure you get into your presentation earlier, so have everything setup and ready to go well before the presentation. Make sure the software is open to files you’re using, your presentation is loaded. If you’re speaking at an event where there’s dinner or lunch being served, don’t sit by yourself – or even with friends. Sit at a table with people you don’t know and at least introduce yourself. You’ll find it’s easier to connect with people before the presentation than during.

2.       Preparation - Practice, Practice, Practice, Practice, etc.

There’s a big difference between knowing something and owning something. As much as I present, even the same things, it’s still a good idea to go through the presentation – night before, etc. I used a short script prompter, which contains the key points and sections. I leave it on the table where my laptop is, if I’m driving, since this helps me stay on course.  But no script keeps you from flubbing if you haven’t gone through everything. I had updated my computer before AU, but didn’t run through the steps in the exercise – my path to the lookup tables for pipe fittings in Revit was wrong…boom – but we turned it into a teaching moment, and showed the class why it broke. That’s rare, but sometimes you have to make quick adjustments. Try standing in front of the mirror – watch your facial expressions, hand movement, body posture – but nothing exudes confidence like owning the material. And never, ever, ever rewrite material the night before. Make sure you deliver exactly what you say you’re going to deliver – set the right expectation for the class.

3.       Relevant Topics – Stay on them.

As much as you may want to teach lisp programming that sets layers to an Architecture crowd at AU, that may not be what the crowd is really interested in. Find something that’s current and fresh – don’t dwell on how you did things in the past, unless you’re using it to define context. For example, a great expression is “I used to do this way, but then I learned a better way”.  And always credit the person who taught you – it shows humility, and respect.

4.       Presentation is everything!

At Bobby Flay’s Mesa Grill, in the Bellagio hotel, it’s all about presentation – getting the fries to be fluffed up a specific way so they look enticing.  A former co-worker of mine, David Garrigus, was a big inspiration – the ball and chain demo on ACAD 2000 was one of the best. You may have a style, but you can’t rest on it. You can keep the style, but change it up – do something different at every event. I may have fishing videos before the class, but every year I bring different props.

One of the things that drives me nuts is a presenter who hides behind a podium or desk, and doesn’t stop and step out. Engaging the audience is mission critical at an event like AU. You want them to share how you feel about what you’re teaching, but say it a little gently.

We even did the dating game once – but I won’t ever do it again. Judge the response – if it works, tweak it. If it doesn’t, run away from it. Don’t be afraid to ask people what they think – but also don’t be depressed if your presentation gets trashed by one or two people. There’s always a critic that thinks they can do better, or wants a specific presentation. Most important – be yourself.

5.       What to do when Things Break Down – and They Will!



Beware – if some disagrees with you, and they will, never trash them or their idea. Say something like, “I hadn’t thought of that, but it sounds interesting.” Many times, and unfortunately, there will be someone in the group that wants to bring you down a notch. Don’t ever play into it – better yet, try to deal with it after the class, and stay on track, so you can finish what you need to cover.



If something crashes, don’t dwell on it – even in a lab, you can still step out, and talk about what you’re trying to accomplish. One of the things I do is keep presentation or lab files saved at critical points, so a user can pick up and keep moving if they get behind, or worse, if something breaks.



And I’m a little superstitious – I always bring two laptops with me, just in case. But Autodesk is great about providing powerful desktop systems that you can use. One of the reasons I get to AU on Sundays is so I can spend time in my labs on Monday, and make sure all of the datasets are current and correct. I don’t recommend trying to customize the AutoCAD or other software on these computers, as not everyone who teaches will share your ideas about how menus suck and keyboard shortcuts are the only way to go. That’s when the dual laptop method works best. All it takes is a little static – and you’re talking about your kids for the next 75 minutes… and getting a crappy score.



To wrap it up, understand that AU is not a traditional training event, so you can’t approach it with the chalk and talk method. Be creative – engage the audience – know your subject – but most of all, have a great time and enjoy the privilege. Not everyone is crazy…excuse me, qualified enough to teach at AU, so make the most of it!
