    Question About Coordinate

    Hi everyone, i have a question.
    - In revit, i use property line to specify boundary. But i just have point of coordinate, so i dont know how to import this infomation to revit.

    1st column is point's number, 2nd and 3rd is coordinate X, Y, they represent for N/S and E/W indicator, the last one is length between 2 point.
    so could you guys help me please!
    sorry for my bad english!

    Sounds to me like you need to acquire coordinates, but without much more info is pretty hard to say, can you post some images, regrds

    Less Clever - sketch the boundary in AutoCAD using the coordinates. Import DWG into Revit and sketch the property boundary over it.
    More Clevererer - Use Dynamo to sketch out the boundary based on the list of coordinates. I don't know right now if the property boundary element can be created through Dynamo.

    I also considered a toposurface which can be created from coordinates but it's not much use for sketch the property boundary afterward.

    I used this problem as an excuse to dig into Dynamo a bit. I created the attached graph to read a text file with coordinate values, one line per X,Y,Z values. I created a 3D cylinder and model lines to form a target symbol family. The graph places a target family at each coordinate location. In Revit I assigned the Length units to Meter and used the Dynamo graph to generate and place the target families. The last step was to sketch the property boundary segments from target to target.

    It was necessary to move the points closer to Revit's origin so they were not so far away, Revit hates that. After doing that, I moved the Survey Point (not clipped) to one corner of the property (target family location) and then used Specify Coordinates at Point at that location using the coordinate values for that corner. This would allow me to export the result to DWG if necessary.

    Love this. How did you "move the points closer"? I could see dropping the first 3 digits from both the x and y since they are consistently the same in all the points.

    I did that the first time when I got an error about the Geometry Working Range in Dynamo. After I changed it to Extra Large I could just use the full values. I don't recall many coordinates being so consistent on other projects, maybe because of imperial units here in the USA? Then again I don't really look at all the coordinates like this usually. More often it is just bearing and distance and one or two coordinates for checking purposes.
