My first post here, I'ts 20:00 and I've been sitting here trying to get this working for 3 hours. I'm going home
Here's what I have.
I was given a dwg CAD data set with no projection. I am trying to make it line up in an existing ArcMap with data from the same area. I have tried assigning it many projected coordinate systems and it always projects many miles to thousands of miles off. I went through the process on ESRI's web site here HowTo: Create custom projection file in ArcMap to align CAD data and got the data to line up ontop of itself however, the cad file draws much to large. It needs to be scaled down. see the first attachment "cad projection". The orange polygon is my GPS data, you can see where it needs to line up to on the CAD file.
There is also a screenshot of the Layer properyies "Layer props", showing the current extent.
Any help, directions to a step by step tutorial or links to another thread would be greatly appreciated.
