Align GIS data to a UCS

[WillGarmer_JMT]

I have several DWGs displaying a mix of CAD and GIS data from a building's floor plans.

Because they are floor plans, the data all overlap, i.e. Floor 2 is in the same coordinates as Floor 1. But, the floors need to be displayed next to each other on the sheets.

For the CAD data, it's easy to attach the floor plans as Xrefs, then move them around to fit on the sheet. Inside the Xrefs, the data all remain on the proper coordinates, they're just moved around on the finished sheets.

The GIS data are ArcSDE layers. Is there any way to move them around as I do with the Xrefs? I was thinking that it might be possible to attach a layer of GIS data and have it aligned with a User Coordinate System instead of the World Coordinate system, but I don't see any options for doing that. I.E. I would create a UCS for each floor, aligned with insertion point of the the floor plan Xref, then have the GIS layers to use the UCS as the origin points of their own coordinate systems.

Restrictions:

* The GIS data cannot be converted to another format or imported into the DWG - they must remain in ArcSDE.

* The GIS data cannot be physically moved - they must remain at their proper coordinates.

* I cannot do this with Viewports - floor plans for multiple floors are displayed on the same sheet and the layers in the Xrefs are just too complex to turn on and off in a viewport, not to mention that I don't know how to turn GIS layers on or off in a specific viewport.

Hi @WillGarmer_JMT,

wellcome to AutoCAD Map Forum.

You are right, it is not possible to show the FDO data from ArcSDE at another location, because the data are related to the assigned coordinate system.

An alternative might be to work with Viewports in Layout.

Create one Viewport for each floor plan.

In the Viewport enable only the layer for one floor.

You can create as much Viewports you like in one layout.

The option to disable layer in vieports is available in layer manager:

Kind regards

so your floor data is not 3D?  if the floors are stacked directly one above the other then each floor should have a Z coordinate for the elevation of the floor?

No, the floor plan data are simple 2D Acad schematics, not 3D.

That wouldn't help in this situation, anyway. The problem is getting the GIS data to line up with the moved Xrefs, without actually moving the data themselves.

Which seems impossible, if the GIS data will only georeference to the WCS, not to a UCS.

Thank you for the reply Brigitte, but your solution will not work for me.

I cannot use Viewports to show overlapping GIS data, because I cannot turn GIS data on in one viewport, and off in another viewport. I can do this with Acad layers, but not with GIS data.

GIS data turn on in all viewports, or off in all viewports. I find no option to turn GIS data on in one viewport and off in another viewport.

Hi,

>> because I cannot turn GIS data on in one viewport, and off in another viewport

That depends on your version of Map 3D, but newer releases can display different maps for different viewports.

any reason you can't move the  CAD layers to the geographic CS?
