You need to transform ALL your shape, not only that .PRJ file.

There are some ways to convert it, the easiest one is:

1] set UTM83 Zone 18 Feet as main CRS with _ADESETCRDSYS

2] run _MAPIMPORT and load the shape, choosing the Albers' one as CRS going in.

It doesn't work, 'cause you surely have not chosen the Albers' CRS as going in: please attach your MAPIMPORT screenshot, I'll prove it to you.

open a new dwg and set the coord system to UTM83-18F.  You may desire to add some dwg layers that you use regulary to the dwg and save that dwg as a template file.  That template can be opened anytime you want to do a map with that coord system.

 

Use data connect and connect to your .shp file.  You will see two heading schema and coordinate system.  The cs will either have your albers listed or <unknown>  if it is <unknown>, click edit coord systems and set it to the alber cs.  and then click add to map.  The .shp will be tranformed onto the UTM83-18f.

 

In Display manager, right click the layer name and do two things, first save layer to a .layer file so anytime you need that layer back in a map you can drag and drop the .lyr file from windows explorer; and second export layer data to SDF which will save the layer in the SDF format.  That can alo\so be dragged and dropped into a map or data connected if your need to query the layer data.

 

You also have the option on the task pane, map explorer tab, tools>bulk copy and create a new shape in the UTM83-18F cs.

Still struggling.  Of the Albers projection, I only have available: 48 States; NAD27 Albers Equal Area, 1:2,000,000 DLG Files, Meter.  I need:  48 States; NAD83 Albers Equal Area, 1:2,000,000 DLG Files, Meter.  How do I get or find the latter? Please, HELP!

 

Thanks a million,

Les

The closest I see is US48-epng.

 

try this.  I think it gives you what you want but don't garantee it

 

mapscslibrary

 

find US48-epng

hi lite and then click the duplicate button

 

US48-epng_1 is created

 

hi lite it and click edit

 

Rename it if you want

 

change feet to Meters

 

click view and see if has the parameters you want.

 

close and then mapcsassign and use it

 

If it is what youy need you're good to go.  Other wise try Corpscon software from the Army Corps of Engineers, that may help.  Tommorrow others will be back at work and may provide another solution.
