Trimble data does not align with map

[mjohnson34M4Y]

My company is moving away from using Plex-Earth and I am having issues aligning my Data points from Trimble Data to the new mapping system.  The Coordinate system Trimble gives me is not an option on 3D Mapping, when searching for a converted coordinate, the map that AutoCAD gives me is a map of the world, and my data points are not aligning correctly.  Could anyone give me any tips?  I've exhausted myself on Google researching and Youtube videos.  Most of our work is in VA, and I have set the plane to my state but it still will not align. Is there something I need to change on Pathfinder? Will my old Trimble data not be able to convert to the new coordinate system?  I would like to find correct coordinates for the map to match my data points, so when imported onto Google Earth, the path we show aligns with Google's view.

"...aligning my Data points from Trimble Data to the new mapping system."
Need some explanation. What Data Points? What Trimble Data? What New Mapping System?

We use Trimble Handheld GPS to gather points in the field for utilities.  Currently we convert them using Pathfinder.  We also are using Plex-Earth4 to bring in imagery.  We are moving away from this due to the Images huge file space and it bogs down the computer performance.  I need to get the mapping system in AutoCAD to align with the GPS points we have already gathered.  I am not sure if I need to change anything on the Pathfinders coordinate system, or if I need to find a certain coordinate system on AutoCAD 3D Mapping.

Mark,
Are you using Map 3D or Civil 3D? Both will handle your task well. As for the Imagery bogging down your drawing, what kind of Imagery are you using? Using FDO (MAPCONNECT) to bring in the Imagery will speed things up no matter what you're using. If you're using MAPIINSERT or IINSERT to bring in a GeoTiff, you can crop to your area of interest to speed things up.
How are you bringing in your GPS points? Is the Pathfinder spitting out WGS84 Lats and Longs? What Coordinate System are you Assigning your drawing? Is there other data in the mix?
Please post your Drawing and Data. (Zippola everything.)

I am using Map 3D now, before we would Plex the map into AutoCAD.  GPS points were also Plexed in.  Pathfinder Datum is WGS 1984, and so far the only conversion of the coordinate system I found is EPSG : 3857 WGS 84.  WGS 1984 is not a selection in 3D Maps.  There is no other data involved.  I have attached a 3D CAD MAP with the GPS data(KMZ).  If you open the KMZ on Google Earth, you should see the problem I am having.

Mark,
OK, I dropped your KMZ into Google Earth Pro and looked at your data. Then I Drag-n-Dropped the KMZ into QGIS and Exported as Shapefile. (Attached-"Sewer Manhole 167) After MAPCSASSIGN'ing a Drawing with VA83-NF, I Drag-n-Dropped the attached Shapefile. It lands in the same spot as Google Earth Pro.
You can use the Bing Live Maps Imagery in Map 3D, or I'd bet you could get some better quality Imagery in MrSID or ECW Format online. Using MAPCONNECT for your Imagery will really speed things up.

Thank you! That worked!
