I need to export Tool Palette(s) from AutoCAD MEP 2012 so that others may use it.However, the drop down menu in AutoCAD does not give me the option of Exporting Tool Palettes.Any Ideas??? Thanks in Advance for your help. Larry

Don't you have to right-click in a blank space on a Tool Palette to access that feature?

John is correct.  In the Tool Palettes dialog your can right-click anywhere in the grey sidebar to see the menu of options.  Select Customize Palettes.  Once in the Customize dialog you can right-click any Palette or Palette Group to Export them.  Keep track of where you send them... then reverse the process in your other program to Import them.

Dave: My company copy of AutoCAD is apparently not acting as a normal seat.  However in 30 years using AutoCAD, I don't think I've seen a copy of AutoCAD "act normal".Here is a screen capture of what I get when I right clik on the gray area of the tool palette I created: When I click on Customize Commands I get:  If I drag a copy of the "Export" command into my tool palette (which is the only place it will let me drop it) and invoke the command I get:    I don't believe any of these formats will support an import into another copy and/or machine with AutoCAD. I am open for suggestions and/or educating me to anything that I'm missing. Thanks in advance for anything you gentlemen or ladies can come up with. Sincrerely, Larry

When all else fails consult your AutoCAD Help file.  Yeah, I know, most times you can't find what you are looking for or the help that is provided is of no real help at all.  What can I say, I did not write the program.To share a tool palette
Click Manage
tab Customization
panel Tool
Palettes. In the Customize dialog box, under Palettes,
right-click a tool palette. On the shortcut menu, click Export.
In the Export Palette dialog box, enter
a file name and click Save.
Click Close.

Hi, Larry!
 
That top menu looks correct to me.  You were in the right place, you just clicked the "wrong" Customize choice. 
 
Click Customize Palettes and try again.  That's the one you need to complete the instruction set I wrote up above.
