    Move project datum

    I have a model from another office. They began modeling the project with their Level 1 at 0'-0".
    We like to show our model with Level 1 @ 100'-0"
    How can I move the entire model up without screwing everything up?
    If I use the relocate project, the level value stays the same, unless I switch to shared coordinates. I don't want to do this. I just want to move EVERYTHING up 100'.
    Can I do this, or am I stuck with switch all the levels to show shared coordinates?

    Section cut view. Grab your levels and move them up 100'. Hope that everything is level constrained.

      most likely this is not the case. I imagine there are detail lines and other such items, section marker extents, grids, elevation crop regions, that will not move with everything.


        The only way this can happen without physically moving the model up the 100' is to use the following:

        1. Access an elevation view, click Manage Tab>>Project Location Panel>>Coordinates drop-down tool>> Specify Coordinates at a Point.
        2. Select a point on your Level 1 level line.
        3. In the Specify Shared Coordinates dialog box, set the elevation.
        4. Select a level line then access the Type Proeprties dialog.
        5. Change the Elevation Base parameter from Project to Shared.

        You could use the Relocate Project tool found in the Manage Tab>>Project Location Panel>>Position drop-down. This will allow you to move the project in elevation, but the Unless you change the Level Lines "Elevation Base" parameter to shared it will still report the elevation at 0'-0"

          Thanks Ron. I called my reseller and this was the same advice I received from them. I was hoping there was an easy way to do it without telling the level to report the shared coordinate, but seems like there isn't and easy way.


            Maybe you can try this:

            1. Create a copy of the document (in case this method screws everything up)
            2. Go to a 3D view of the whole building. Make sure you have everything visible.
            3. Select all, Group and export. Make sure you also attach detail items and stuff.
            4. Empty out all geometry, detail items and stuff
            5. Move the elevations 100mm
            6. Pull in the group and relocate
            7. Place the attached detail groups on each view. To do this, go to the view, select the group, click Attached Detail Groups and place the appropriate Group

            This should fix it, but I never tried this on a whole project before.

              For a new project moving the levels is fine.

              But a almost done project I extremely advice against just moving the whole project you are asking for trouble. you will need to move all of the sections, elevations and details views up too. Its not fun for a project that is almost done. Your best bet is to:
              1. Go to a elevation any elevation
              2. Under the manage tab go the Position button
              3. Use the Relocate Project
              4. Move the project up 100'
              5. Your levels will still say 0'-0" but this is ok
              6. Select a level and edit the type and change the Elevation Base to Shared
              7. You also need to change any spot elevation to Shared.

              Your model is still at 0'-0" in Project but in Shared it at 100'-0". just depending where you set your Elevation Base. You do not need to change any Section, Elevation or Details view up this way and it keeps your project intact..

                Just out of curiosity, why do some offices use 100'-0" for level 1? When linking in an architect's model, we typically match the levels that are used in that model. Sometimes it's the actual elevation (from civil) or other times it's 100'-0". Is there a reason 100'-0" is chosen over 0'-0" for level 1?




                  I'm sure you now know the answer but, it's so that you wouldn't have negative values for levels below the ground floor.
