Let me break it down for you... Print E-mail

Recently I had our general superintendant drop in and ask for all the floor plans color coded by floor.

Piece of cake.  I cranked them out, included a schedule with it and he was happy... for about an hour.

Later he came back and asked "well, can I see all the floors as seperate 3D plans?"

Okay, so this time it was a little more work, but I cranked them out... but this time I had to tag the floors using text boxes, since Revit won't let you "tag all" in the 3D view (gah!)

 

Well, it took about 8 hours (gimme a break, I've got a 16-story 700,000 SF building I'm working with here), and my super was happy...

For a three whole days.

 

The latest?  He'd like 3D gridlines.  For a guy who's been in the industry for 35 years, he certainly does like this "BIM stuff" ...and I'm paying dearly.

 

Well, I just finished printing it to PDF.  Hopefully he likes it, and maybe you guys will too!

A big shout out to David Kingham for his sweet purple 3D gridline family (tweaked by Laura Handler & Company

...but the parameters I'm using for those tokens, now I've got a little secret sauce of my own in there that really helps when setting up a new project and exporting to ACAD. :-)

    Thanks John, I used to use something similar for the grid intersections but they became a bit cumbersome to keep updated (I was using a structural column family so it knew what the grid intersection was) this became problematic as well because the beams now wanted to host to the geometry of this new column. I'd be interested to see how you're achieving these

    It's a pretty simple piece of geometry (generic object) with instance parameters assigned to an Alpha & Numeric Parameter.

    That way I can select all my markers along a E Gridline, assign them to E, then grab all the ones along the 5-line and do the same.

    It's not "automagic" but it allows me to setup my gridline intersections in short order... I also specified a separate object style to the model text from its hosted generic object so that when I export it to ACAD, it shows up on a different layer that my trade contractors can play with.

    Make sense?

    Ahh ok, that's simple enough, I never thought about doing 2 parameters, that makes it a bit faster.

    Any brilliant ideas on a way to enter a room number and have navis automatically jump to this point? The only way I could get close is to export to ifc, then you can select the space, but since there is no geometry you can't use View Selected...
  • Brad Clark  - good idea...
    John,
    Interseting strategy - I usually export gridlines to AutoCAD and then link them back in to visualize in 3d which seems like less work, initially anyways. What is the long term value you get from your approach?
  • John
    There's a couple of things here that make this a better solution than autoCAD:

    1) The gridlines are a parametric family that David Kingham cooked up, so the lines themselves have little breaks along their path with either their letter or number inside it. Really helpful for close-up 3D views, since section boxes don't crop gridlines like 2D views do.

    2) Linked AutoCAD geometry is the devil. Seriously. AutoCAD files slow down revit, and revit has a real hard time cutting ACAD stuff in 3D views, or just cutting ACAD stuff in general -- it's ugly. I group my gridlines and put them on their own workset.
