Civil 3D 2-digit Spot Elevation Labels Done Right

Until today I have been using a spot elevation label method that returns 4.56 instead of 04.56 for the elevation 1204.56. See my earlier post on Abbreviated (short) elevations in AutoCAD Civil 3D 2009. (2018 update: After talking to various people, I still have not found an easier way to do this. To quote Chris Stevens of City of Goodyear, "It's a good thing I am the only person who ever has to do this." But if you don't mind seeing 4.56 instead of 04.56, my earlier and easier method will work for you.)

I just tested successfully a new idea for showing two-digit elevations (04.56 instead of 1204.56 or 4.56) (2014 update: I have corrected it to also show 1204.9999 as 05.00 instead of 04.00):

1. Under Toolspace, Settings, Surface, Label Styles, Spot Elevation, Expressions add an expression named "Surface Elevation hundreds" ROUND({Surface Elevation}*100)/10000

2. Under Toolspace, Settings, Surface, Label Styles, Spot Elevation, <your style>, Edit, Layout tab, enter this where you want the two-digit elevation:

This is the code that needs to end up in the right pane of the Label Text Component Editor:

<[Surface Elevation hundreds(P2|RT|AP|GC|UN|Sn|ORD)]><[Surface Elevation(Uft|P2|RN|AP|GC|UN|Sn|ODS)]><[Surface Elevation(Uft|P2|RN|AP|GC|UN|Sn|ORD)]>

In human language, the above adds the elevation in three pieces. For the elevation 1204.56, it adds 1) the "04" from 12.04, 2) the "." from 1204.56, and the "56" from 1204.56.

Explanation for elevation 1204.5588:

Code	Result	Explanation
<[Surface Elevation hundreds(P2|RT|AP|GC|UN|Sn|ORD)]>	04	ROUND(1204.5588*100)/10000 = 12.0456. Truncate it to two decimal places => 12.04. Output what's right of the decimal => 04.
<[Surface Elevation(Uft|P2|RN|AP|GC|UN|Sn|ODS)]>	.	Output the decimal sign from the surface elevation => "." (in American English)
<[Surface Elevation(Uft|P2|RN|AP|GC|UN|Sn|ORD)]>	56	Output the part of Surface Elevation right of the decimal => 56

Explanation for elevation 1204.9999:

Code	Result	Explanation
<[Surface Elevation hundreds(P2|RT|AP|GC|UN|Sn|ORD)]>	05	ROUND(1204.9999*100)/10000 = 12.05. Truncate it to two decimal places => 12.05. Output what's right of the decimal => 04.
<[Surface Elevation(Uft|P2|RN|AP|GC|UN|Sn|ODS)]>	.	Output the decimal sign from the surface elevation => "." (in American English)
<[Surface Elevation(Uft|P2|RN|AP|GC|UN|Sn|ORD)]>	00	Round the Surface Elevation normally and output the part right of the decimal => 00

I would LOVE to do Civil 3D consulting work for any of you at any time. And I am happy to share with you my template styles.
