I'm building a VBA application that requires 3D (2D + Height) ID information from one drawing to be used in another one to ALIGN it.

In setting out we get snippets of a project drawing in a local coordinate system in mm. and need to manipulate (scale mm => M. and align to new coordinates) it into a Project Coordinate System (mostly flat OS) for production setting out in M..

I have two or more drawings open, collate at least 3 (2D + H) points in the overall PCS system drawing and align the other automatically to these 3 global points with ALIGN.

At the moment I'm running my application in 1 drawing, store the info, close my application, open the other drawing and run my application again to retrieve the stored info to align the drawing automatically.

It needs to run and use all other drawings to give the focus to on demand.

Any ideas are welcome.

Thanks.
