But before you do the Define Query there are a few things you need to do.
– Make sure the original drawing has been exported to Vanilla AutoCAD – Big Blue A – Export Civil3D Drawing
– Open the exported Vanilla AutoCAD drawing and make sure everything is there.
– Any points that were Civil3D COGO points will then be exploded back to AutoCAD Blocks
– In the Settings Tab in the Toolspace – right click on the drawing name and select edit Drawing Settings set the unit and zones in here – this should be set to PCG94 (or whatever the co-ord system you require)
– Save the drawing.
– Exit out of the drawing.
Open a new drawing and make sure you do the following
– In the Settings Tab in the Toolspace – right click on the drawing name and select Edit Drawing Settings. Set the unit and zones in here – this should be set to MGA-55 (or whatever you need it to be)
After setting the coordinate systems to the two files, these are the steps to use.
-Type in command line MAPWSPACE – select ON (image 1)
-Click on the Map Settings tab (image 2)
-Right-click on Drawings (image 2) – select Attach – navigate to and select file you want to transfer from
-Right-click on Current Query (image 2) – select Define – Query type = And, click on the Location button (image 3) – Boundary Type = All, click OK (image 4)
-Query mode = Draw, click on Execute Query button (image 3)
-check both sets of coordinates for one of the transformed points. Use a third party source to verify. Example: include an SSM and check the land authority coords
Have a go at this and see if you can get the transformation done.
