Shared Coordinates in Linked Models

[Anonymous]

Working on a residential  compound of buildings - I have linked the garages into the main house model. After using the relocate project to get correct topo elevations on my site plans, 3 out of 4 of the garages stayed at their original elevations. I am curious if i set up shared coordinates incorrectly? Why did those 3 garages not move up with everything else?

I'm not understanding your workflow. How/why did you use Relocate Project?

We received a topo survey recently and this main house model had been built with project base point and survey points at 0,0. Now that we have grading plans, I "relocated project" to our determined FF elevation relative to sea level. This gets my contour labels to show relative to sea level and keeps the rest of my level datums relative to the main FF. 

Before using "relocate project" I tried to lower the survey point to -1006', thinking that my 0' contour would show as 1006' but that was not the case.

Lower the Topo and Survey Point in the project - not the project. Then set your Spot Elevation's "Elevation Base" to "Survey Point".  Position/Orient your Links in the Project and Publish coordinates.  

..I think this will help you:

I already moved the topo (-1006') into the correct location relative to my buildings. Lowering the survey point by the same 1006' did not affect how my contours were being labeled. I toggled the "elevation base" of the contour type properties between survey, project and relative, and they all kept showing as 0'-0". 

Because this didn't work, i used the "relocate project" as described above, which has correctly updated my contour labels but has left some of the linked models behind.

I missed your to the aubin PDF before, I will read through that over lunch. Thank you for your input

Hey @Anonymous. Did the information in the PDF help you figure it out? Are you rocking & rolling now?

Yes I found that informative but nothing there helped fix my problem.

Perhaps due to my mislabeling of the title, but I was primarily concerned with getting topo contours to be labeled correctly with sea level elevations. I moved the survey point down by 1006' but the contour label would continue to annotate elevations relative to 0'0". So I ended up disabling the "shared site" feature of those 3 linked models and did the "relocate project" method to move it 1006' vertically. This left all of the annotations and datums relative to the primary finish floor and allowed the contours to show their sea level elevation.

Thank you for your input @barthbradley

You could have simply moved the clipped Survey Point up or down and change the Contour label to reference the Survey Point instead of the Project base Point.  No need to relocate your project at all.

Sorry to hear that, @Anonymous. Maybe I have misunderstood the issue. But seriously, I do this for a living and the "relocate project"/"disabling sharing" workflow you're describing is very odd to me.  If you could walk me through the ABCs of what you're doing (e.g. what's getting Linked into what), I could probably suggest a smarter workflow to use.  

The offer is on the table.

I've got a compound of 5 buildings arranged over a couple acre site, connected by covered walkways, all going into construction simultaneously. 

To simplify printing and detailing, I am doing all of the site work and CD drawings (notation, dimensions, sections, schedules, and details) in one central model. The individual buildings have been cleaned up in their own files and linked in to the site model which allows me to move them as needed. 

Not sure at this point what I was trying to accomplish by publishing coordinates between models...but that turned into a headache when I tried to raise one of the garages in elevation relative to topo. Every sync would generate several pop ups saying that the coordinates were to be published to that one model. Additionally, when I tried to relocate the model to fix the aforementioned topo issue, 3 of the models remained at their 0' elevation.

Lesson learned: should have moved the survey point when "clipped" and probably didn't need to do anything with shared coordinates. I did use the "relocate project" feature, and it did exactly what I wanted, and did not ruin any drawings or model relationships.

I am open for input and always want to do things correctly but I do not believe shared coordinates would have been useful for this project. When would I have wanted to use shared coordinates? If I was doing full cd's in each separate model and wanted to link in the site as background? That would have been a nightmare for revising details...
