I am using AutoCAD 2015 and am trying to make an Elevation Marker that will updated the elevation of the block automatically based on where is located within the drawing. I have created my initial block based on Object Fields but even when I moved the UCS/Origin the block does not update. I would like it to update based off of a user defined point. Any tips on how to do this?I would like to note that yes, after I have moved the UCS/Origin I did regen my drawing.

Bristo_11, you can use the command DIMORDINATE to lay an "elevation" dimension.
When you do this there is a grip at X:0 , Y:0 , ( Z:0 ) for that dimension(s).
If you move your object with that DIMORDINATE dimension the "elevation" will not change.
Only if you STRECH it the DIMORDINATE dimension will be updated.
You can move your object + DIMORDINATE dimension and then re-grip the 0,0,0 grip at 0,0,0 and the dimension will be updated.
 
If you create a new DIMSTYLE with good settings you can ( for example ) have a dimension text like :
+ 1075.523 m for an elevation of 1'075'523 mm drawn on your file.
 
If it's a 2D drawing the DIMORDINATE is really OK, if it's 3D it's also good with some precautions.
Personally in 3D I use a "target" + multiline text of good width that I copy at the good place and use the ID command to get the coordinates on the command line and copy paste them in that multiline text.
That text won't be updated when moved.
You can find 2D blocks that will do the same right here in the site in the CAD Blocks library like:
ElevPM.dwg , Kacena_UCS-Level.dwg , VertID.dwg , PXY_Leader.dwg , AttPoint.dwg , etc...
I have done my 3D one copying a 2D one but the Z dimension doesn't work, available if asked.
Tell us if this helped or not.....philippe JOSEPH2014-08-05 08:11:58

There is a block of an elevation marker with Y-coordinate relative to UCS in the CAD Blocks section - see:http://www.cadforum.cz/catalog_en/block.asp?blk=9688

Thanks for the responses. The Kacena block is kind of what I am looking for, but is there a way to adjust the elevation without moving the UCS? I like having the UCS set to World which is in the lower left corner of my titleblock.Also is it possible to know what kind of Field the Kacena block is using? I would like to tweak it if at all possible.
