Shared coordinates query

[chris_curley2]

Hi,

To my surprise on a project where 3 discipline models are coordinated using shared coordinates and no coordination issues arise (in revit or navisworks), those 3 models do not have the same project or Survey coordinates. I did not expect that the project coordinates would need to be the same but I assumed the Survey coordinates and elevations would all match.

Thus far and from multiple sources I believed that when coords where acquired from a linked model the survey points were matched. What am I missing here?

assuming all links would need to have the same coordination since they are all being linked.

If the survey point was unclipped then moved then its symbol location does not affect the shared coordinates.

Thank you for response.

I now get that the SBP can be unclipped and moved without any affect on the shared coordinates.

I know however that the SBP was not unclipped and moved and have recreated the issue where the SBP does not align to the acquired SBP but to 0,0,0. This is not what I expected as in a number of other exercises I've done the SBP aligns to the acquired SBP. So that is all that is leaving me confused at present.

Grateful for your input.

Chris
