Did a little googling.

I can see ImportPlacement, but not specific the options you want but maybe they are in this class, haven't tried it.

Hi,

We need to link Revit file with shared coordiante, but we have not found option for doing it programmatically.

Thanks a lot for kind help and support in this regards,

Warm Regards,

Hi @MehtaRajesh,

I'm trying to enable my script to chose the positioning of the file that is going to be linked. Did you find a solution?

I had a look at the APIs but I didn't really see much.

Thanks,

Andrea

No, I have not found

Not sure about CAD files but Revit link instances can apparently be inserted by shared co-ordinates or have such a system set up via the API.

To set up shared co-ordinate system use

Document.PublishCoordinates (Since 2018)
or
Document.AcquireCoordinates (Since 2018)

Just like in UI you would have to move instance to the correct relative location before using either of the above.

To create an instance of a link (where an existing shared relationship exists) use:

RevitLinkInstance.Create Method(Document, ElementId, ImportPlacement) (Since 2013)
(ImportPlacement.Shared)
