Hello,

Lets say I have a building that has levels of 0, 300, 600 and 900. Is there a way to change levels as 200, 500, 800, 1100? What I mean is can I elevate the whole building on a specific level?

well, yes!  If you want to have your building start above zero, go to an elevation view.  In the elevations, you can see the level lines and bubbles, and you can select them and change their values. Or simply "move" them upward.

if I do that all walls and other building elements go crazy, I don't use attach to top or base. Any other solutions?

It's a good idea to have a top constraint for walls.  Even if you have a 3 foot wall, from level 1, it's better to say: start constraint, level 1, top constraint, level 1, with a top offset of 3 feet.  "unconnected" can be a pain in the @$^. 

But this should not screw with your project, really.  Although, it could be... it's better to start moving up layers from the top, and progress downward.  so that you don't squish levels--you stretch levels. For example, if you move your level one up so it's only one meter from level 2, you're going to get errors when doors don't have enough room to fit.. if you see what I mean.

Alternatively, you can select all the levels at once and move them up.  I believe that would work.

itsmyalterego!!!  you should know better.

1.  Why do you want to change the elevation?  Is it for topogoraphy, or was it just the wrong elevation to begin with?

2.  If it's the topography, can you just move it down for what you need?

3.  It's much easier just to SPECIFY COORDINATES AT A POINT.

Here is how to do it:

1.  Open an elevation view where the levels are visible

2.  Go to Manage -> Coordinates -> Specify Coordinates at a Point

3.  Select a Level

4.  Type in the new elevation.

The Level will not change elevation - you have to tell it to read the shared coordinates.

5.  Select the Level

6.  Edit Type Properties

7.  Change Elevation Base from 'Project' to 'Shared'

If you have spot elevations, you will have to change those type properties to read the Shared Coordinates too.

Make sense?

Also, if your file size is small enough, and you haven't documented too much you could try linking the project into a new template, binding it, and try taking all of the levels and details with it.  You will, of course, want to move the project to the correct elevation before binding and ungrouping.

Max file size according to Revit is 10MB.  You might be able to get away with a larger file (25 or 30.)  I am typically most comfortable with this method.  Be prepared for benign error messages.

And as for the topography.  On second thought - it may be possible to change the origin of topography with the project base-point.  Not sure how that works since I'm working in RST most of the time, and rarely have to deal with Topo's.

Good luck.  hope it helps.

I'll defer to stronger opinions!  And that technique would definitely work... Admitedly I haven't had to move floors more than maybe 10 feet.  And changing the elevations of the level bubbles--even when it's relatively drastic--hasn't caused me any grief, and grief is the #1 impetus for changing behavior.   The firm has gotten pretty anal about having a good idea of the floor spacings prior to beginning work in revit, and most large changes predate linked consultant models.

i highly recommend NOT trying to move a building from its original location..

if i discover i have built the building in the wrong location- i will tear it down

and build it in the right location..

you can't get anymore "virtual" than that..

cemcem,

emgeeo is exactly right, that is a great function and easy to use. To rebuild your project is the worst idea I've ever heard.

yeah good luck is right..

that little house i just built is 41.3mb and i have not yet started any sheets or detailing..

i could remove everything down to the walls- floors and roof and just move those main

elements and then put eveything else back in less than one hour.. no "benign error

messages" ever..

this is what has been an inspiration to me for the last 5 1/2 years with revit- even though

i am not as artistically talented as some- i know how to use logic- and revit craves logic..

Oh thank god, I was worried for a minute. Thankfully Vector is here with his brilliant mind, tiny house and huge file sizes to save us all from our certain BIM demise.

*breathes huge sigh of relief*

Do you mean move the building levels up while keeping everything in the same relative place? If so, go in to an elevation view, then on the "Manage" tab, use the "Position" tool to move the whole project to the level you want it at.
