Global origin incorrect

[Karl Wir_n]

This is a recurring problem in our office at least since Archicad 15. Sometimes the global origin is no longer in 0,0 in some project files. I have tried to reset the user origin, restart Archicad and selected the "open and repair" option on start.

Everything looks as if the origin is in 0,0 in the plan view but when you drag parts into a gdl-script the coordinates are way off. Anyone who's got a solution to this? The picture is from a project in AC24

If by Global Origin you mean Project Origin, then that is always at 0,0.

It can't be moved.

You can however set a User Origin where ever you like.

They both appear as a little cross.

The Project Origin will be grey if you have set a User Origin position.

To reset the User Origin back to the Project Origin, double click the 'Set User Origin' button which you can find in the Coordinates Palette (which I think should always be turned on).

Then anything you model at the Project Origin such as a hotspot will script with 0,0 coordinates.

Thank's Barry for your answer but as I wrote I already tried to reset the user origin. That is not the problem. The problem is that although things are placed in 0,0 at the floor plan the coordinates in a gdl-script don't correspond. 

If I copy elements from the corrupted file and paste into a new document (paste into original location) they land in 0,0 on the floor plan and get coordinates 0,0 in a gdl-script. As I wrote this is not the first time we have encountered this problem and I wanted to know If other people  have experienced similar issues.

I have not seen this.

If you place the Coordinate Dimensions object at the Project Origin and a close by User Origin, what does it show?

Has it got something to do with Location Settings or a Survey Point Location?

I have tried playing with those but Project Origin is always 0,0.  for me.

There is a script at page 432 in the GDL ref. guide (Ac24). With this script you can separate the "world origin" from the "virtual origin" and the "object placement". I don't know what a "virtual origin" is but in my file the world origin differs from the virtual origin. It seems as if the virtual origin is the real 0,0 since if Idrag a hotspot from this point into a gdl 2d-script it reads hotspot2 0,0.

If I place  coordinate dimension objects as in Barrys example it shows this:

World Coordinate for use with survey points...

or

i think its described in the manual "02 ARCHICAD 24 Reference Guide.pdf"

Have you placed any survey information into these files?

i don't know if this helps...

[Karl Wir_n]

Additional information: no survey point has been placed in the project.

It's actually the opposite, but let me explain.

The so called "virtual origin" is being placed only when you model your project far from origin. This is being done on opening an affected project as housekeeping (not while having a file open). This virtual origin will then transparently used as an internal offset modifier. This is being done to mitigate all the issues that otherwise would harm the integrity of the project.

So, what do you need to do? –> Model everything close to the real origin point.

Thank's runxel for putting me on the track to a solution. It turned out that in the beginning of the project I xref:ed a 2d DWG from another company into the project. At a later stage I bound the DWG to be able to make some changes. I discovered now that in that DWG there were some extra lines very far from the origin. I guess this caused the problem. The solution was I deleted the lines far away, saved, closed and restarted Archicad. Now zero is actually (not virtually) zero again.

Probably I have a similiar issue here ... but I don't have those extra lines so not sure what to do now ....
I actually tried to delete everything to see if there is another culprit but nothing changed.

Any other ideas what to try or why this shift of the internal origin is happening?

Edit: Sry, seems like a total reset (meaning, deleting everything was indeed setting the project location back to 0/0/0, just forgot to restart.
Ok, so cool, I just don't know which elements are to blame here but I guess I'll find out ...
