The two shp files are not aligning like they should (note the img). The layer and the two shps all have the same coords - NAD_1983_StatePlane_North_Dakota_North_FIPS_3301_Feet

The surface shp came with the defined coordinates so I imported those coords into the post plot which had "undefined" coords. They did not align. I checked the Layer coords and they were the same as the surface shp.

I deleted the coords from the post plot shp file which originaly had "undefined coords" and started from square one with the post plot shp coords. I re-imported the coords and I get the same results. I used ArCatalog to put in the coordinates. I have Arcview 9.3

What am I missing or not doing? I've always been able to fix this issue except on this occasion.

Thanks, Z

Hey, I figured it out. When I saved it, I gave it a differant name. Then when I re-downloaded it and kept the original name, it fell right into place. Z –  Zoran Jul 16 '11 at 23:53

A shape file is actually a set of files.
*.shp, *.shx, *.dbf are required.
The *.prj is where it gets it's prjection from.
When renaming a shape file all of the associated files must have the same name and be in the same directory.
It sounds like initially you renamed or moved some of the files but didn't get them all. Good to hear you figured it out.

good to know, Brad. I've changed the name of it before but this is the first time this happened. Always a first time for everything. –  Zoran Jul 17 '11 at 13:19

If you rename it inside arcGIS, the other files will be renamed automatically. Doing it manually through Windows Explorer, however, could cause some issues. –  Nathanus Jul 18 '11 at 21:12
