revit-problem con coordinates

[net]

Hi, I'm new to both the forum and revit. I have a problem that I can't solve despite the thousand searches both on manuals and on various forums, my problem is about coordinates. I have a dwg planimetry and revit collego choosing as an option "from origin to origin", in both programs it is set as a meter unit, control the coordinates for example of a corner of the building and the two programs give me different coordinates (the right ones are in cad). How do I properly georefer the planimetry? how amount the planimetry keeping the original coordinates then making the origin coincide?

how did you set the coordinates of the project base point?

 

[net]

I did not touch them, I would like the zero of the two files to coincide then the coordinate on cad e.g. x=200 y=0 corresponded on revit n=200 e=0. What setting do I have to give?

 

[Tristan]

Do you know at least how the project base point and the revit detection point work? If the answer is no, start from there

 

[net]

I know that the basic point of the project is a relative point of reference to be set with respect to example to a edge, the point of detection instead is the materialization on revit of a precise point such as a mark. Now my question is: how to make the zero of cad coincide with the zero of revit so as to have the same coordinates? like a "glue with original coordinates". about the coordinate system on revit I read a lot about project origin point, point of detection and project base point but I don't know what settings to give to get accurate and accurate coordinates

1. it is necessary to have a .dwg file with at least one point identified with coordinates.
2. connect the .dwg file to the .rvt file. use center to center.
3. [Opzionale] move the dwg file to another place. For example, choose an important point of the dwg file and move it to the origin of the revit file.
4. use "manage > coordinates > specify coordinates at point" on that known point that I nombered in number 1.
5. writes the cohorts of that known point.
6. the detection point will move to 0.0.
7. now, the coordinates of the .dwg file and the .rvt file are the same.
8. to not need to repeat these things next time, it is used "publish" coordenate, from .rvt to .dwg.
(but this and another theme). :smile:

Thank you very much!!! very kind and very useful! :smile:
