Create element in specific coordinates

[mairh_tsek]

Hello all,

How can I create an element (let's say a pipe) in specific coordinates in Revit?  I received the coordinates information X,Y,Z  for different pipes that I need to create in the georeferenced model that I have.

I tried to create a sphere , check its coordinates and move it manually in the coordinates that I wanted. After I created the pipe in this position .

Is there any other smarter way to do that ?

Thank you in advance!

Not sure I understand. the question, @mairh_tsek.  All geometry has spatial coordinates.  Revit orients geometry "spatially" relative to datums (e.g. Levels and Grids) -- and other geometry.

FWIW: the survey origin is 0,0,0.

@barthbradley  ,

Ok, for example, they measured by laser, the coordinates( x,y,z ) for the lowest point of this cable (see image). I need to create this cable in Revit, in these coordinates. 

x: 2490471,24

Y: 1203179,97

Z: 454,70

the Revit model is georeferenced, So project Base point and survey point have coordinates too

How can I do it ? 

Thank you for your time.

I think that you can try this:

• In the Site Plan with surveyor coordinates, select Project Point > Unclip it and type the desired N/S, E/WW and Elevation Coordinates
• Draw a Model Lines starting from Project Point whatever direction
• Move the uncliped Project Point to next Location and type the N/S, E/WW and Elevation Coordinates
• Drag the other end to the new Project Point position.  
• Repeat the process so to create a chain of Model Lines in 3d space
• relocate the Project Point and clip it back

So it's located at E/W: 2490471,24 N/S: 1203179,97, Elev: 454,70 in the Revit -- assuming that the Revit Project's Survey Origin is the same as the CAD Origin.  

Maybe this is the right answer. Maybe not. This is not a question for us.

@barthbradley ,

Hello, when you say CAD origin? I dont have any CAD file

[barthbradley]

Point fie?  

[mairh_tsek]

I just have the coordinates in an excel file. And I want to find in revit where they correspond in order to create the cables. 

[constantin.stroescu]

if you have the table of coordinates in Excel then the work is almost done..

• open the Excel File 
• get rid of all columns except X, Y and Z  . No header, no units, just the number values on 3 columns
• save the file as .csv
• in Revit > Massing and Site > Toposurface > Create from Import > Specify Points File - choose the .csv file previously saved from Excel.
• the Toposurface is created.

@constantin.stroescu 

But I dont want to create a toposurface.. 

[constantin.stroescu]

then on what do you want to place your objects?

• I agree that is not necessary to built your Toposurface but you have to link then the CAD file into your Revit File so to be able to Acquire Coordinates from it.
• Once you've Acquired the Surveyor Coordinates , then wherever you move in your Site View you will move in a space that share the same values with your  Excel file values.
• Now, in order to identify the Points from your List on the Site Plan , proceed like I've shown in my previous post:
  • select the Project Point symbol from the Site, unclip it and type the values of one of your Points from the Excel List (X as E/W  , Y as N/S  and  Z as Elevation)
  • Then place a mark snapped on the new Project Point position ( or begin to draw a Model Line as I suggested before) 
  • then still with PP unclipped load other point values and continue .
  • you will obtain a chain of Lines or other references at precis Survey Locations.

[constantin.stroescu]

I have to make a correction to my last post.

Instead :

 wherever you move in your Site View you will move in a space that share the same values with your  Excel file values.......

Should be:

wherever you move in your 3 d MODEL  you will move in a space that share the same values with your  Excel file values.......

Huh? This is very confusing, @mairh_tsek .  Can you post this Excel file?
