Revit Coordinates (X,Y)

[mairh_tsek]

Hello all,

Every time that I start a new project I am getting anxious with the coordinates. Could you please someone tell me the 'steps' that I need to follow for the following case:

I have a project with an angle (from the North) and the coordinates (X,Y). I know that I just need to give the angle in the True North and after in order to design I need to change the properties in the Project North. 

What about the coordinates X,Y? I will put this value in the survey point?

Hope to make sense.

Thank you in advance!

Depends on what your modeling...a site or a building? You don't need to worry about the Survey Point if your modeling the building, and for that matter, nor the Project Base Point. Once the building is ready to be oriented on a site/to the real world; then you can start setting up the SP and PBB's Angle to True North.

...I'll add, that the power of the SP is actually realized when you start using Shared Coordinates/Positioning.

It is a building but after maybe I will create the ground too.  Until now the project is designed in Allplan, and the coordinates are defined. So in Revit I would like to start the project correcty with having these coordinates. For me the level 0 will be the ground floor (so the project base point) and for the values X,Y that I have? I will put them in the survey point?

Thank you!

You're welcome, but is there a question in there, or are you just sharing your strategy with us?

No, it is a question..

I think you might be a little confused about coordinates in general. Let me know if this link helps clarify: https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/CloudHelp/cloudhelp/2018/EN...

By default, revit has a hidden "origin"--which lies at the center of a default plan view, in the standard template which shows (4) elevation tags.

This point is not exposed--but it is used as an "origin" similar to AutoCad's 0,0,0.

Here is a really good explanation--it is long, but worth the read and for future reference when working in Revit:

That's a good source @cbcarch. Also, another Pro out there is @SteveKStafford. Maybe, he'll weigh in on this.
