Thank you all for your input regarding Revit MEP.  It had been a big help to
us!

Ryan,

 

I second everything Shaojie said.  Our office uses Revit MEP on a regular
basis (we work with a lot of architects who are serious about migrating
over), but we only use it for mechanical design and electrical fixture
layouts.  All plumbing, circuiting, panel schedules, riser diagrams, etc.
are still done in AutoCAD MEP.  Revit is pretty weak on the plumbing side,
and aside from showing the location of lights and receptacles, we consider
it weak on the electrical side compared to the tools we've set up in-house.
It's supposed to be great at doing your schedules and other back-end work,
but like Shaojie said, you spend so much time on the front end getting your
families to play nice together that we're not convinced it's completely
worth the extra time and cost.  Plus, the training support is still pretty
limited.  We've been so frustrated with it that we've hired a third party
trainer to come into the office and conduct classes for a couple days, but
that's extremely expensive.  It's best if you have a person in the office
who has the bandwidth to become the in-house Revit guru while everyone else
is getting up to speed.

 

Of course, it's always a good idea to get the learning curve under way if
your budget can accommodate the license fees, but it will put a huge strain
on your production schedule if you try to switch over night.  A slow and
steady migration, one project at a time, is what I would recommend if you
choose to go this route.  Put a couple buffer weeks in the project's
production schedule, too.

 

As far as the supplementary energy modeling tools in Revit, I'm not that
familiar with them.  We've spent so much time trying to get a handle on
eQUEST that we're not quite ready to start branching out into other options
yet.  If I were in your position, though, I would start by finding out if
Revit's tools meet the software requirements outlined in ASHRAE 90.1.  If
not, don't waste your time with it.

 

Thanks,

Hi Ryan,

 

I used Revit MEP 2008 about a year. Per my experience, the mechanical part
of Revit MEP is ok to use. The major difference between Revit MEP and
AutoCAD is that everything is based on 3D. The big challenge for me is that
I can't find the similar commands I used to have in AutoCAD. And Revit makes
my pc very slow because it recommends having 4GB memory. You can download
the most of families (similar to the "block" in AutoCAD) from Autodesk
website.  However, you still need to spend lots of time customizing the
"family" per your equipment selection. The fast way to learn it is to setup
in-house training and work on real projects instead of going through the
tutorials. In the first couple of weeks, you maybe want to throw your pc on
the street because you are so angry with Revit. In short, AutoCAD is a good
drafting tool but Revit MEP makes your 3D drawings look so cool. 

Good Luck!

Shaojie

Hi everyone,

 

Sorry for the cross posting.

 

Our office is thinking about buying a license Revit MEP.  Does anybody out
there have any experience using it?  Any comments about it?  I heard that it
still has a lot of bugs to be worked out and may be a bit of a headache
until the "issues" are resolved.

 

Also, does anybody have experience working with the supplemental energy
modeling programs that work with the Revit MEP models such as IES or any
other softwares?  How do they compared to eQuest or HAP?  Do the
supplemental energy modeling programs available today simulate the actual
systems drawn in Revit MEP or do they just share building envelope geometry?

 

Thanks for the input,

 

Ryan
