Hi David
If you are using TeklaStructures to produce your DWG then all you have to do is:
- set the following in line a role or firm initialisation file - set XS_DWG_EXPORT_3D_MODEL_COORDINATES=TRUE
- highlight the drawings you want to export in the drawing list
- choose to export them
- make sure you choose model coordinates in the export dialogue
- also export your model with model coordinates to IFC
When you view the model and drawings together they will be overlaid.
If you plan to use this feature in the Hololens I would also export each assembly into its own IFC.
regards
Steven
