How can I create civil labels that have mathematical expressions on them just like in Inroads SS2 Drafting tools.
For example, if a pick a close shape to label the area, I can add an equation to the label to output the value in hectares instead of the value in the design file's master units (m).
Thanks.
ChrisMat:
You will need to create a text favorite for this issue which will be accessed via a Civil Label/ Civil Labeler function.
Literally, the label code would be Polygon.Scaled Area, which would be created via the Text Favorite Manager, Field Type: Civil Element Properties> Field Sub Type: Polygon> Scaled Area, or one the other methods as you seem fit to use.
The design files master units really have nothing to do with the Civil Formatting which OpenRoads uses. I would suggest that you got to the Backstage> File> Design File Settings and check the Civil Formatting options in that dialog. More than likely, your Drainage Results settings have been set to Area Format: m2 rather than ha. As well, there are "override" settings when creating the text favorite in many cases. In any case, quite a few methods of setting units.
You can also use Item Types, but I do not wish to confuse the issue ;-)

Hi Mark, thanks for the reply but not really asking about the units setting but was just giving the sqM to hectares conversion as an example of where I want to use mathematical expression on civil labels.
Another example is a label to show elevations label based on a datapoint, the value is converted from metric to imperial (vice versa). I've also done this with coordinates, on a site where 2 coordinate systems are used. This was done without changing design file settings but just with an equation on the drafting label on Inroads SS2. Not sure if this is a capability in ORD civil labels or not.
Ah, I see. Within the text favorites dialog, there are often mixed units which one can use. You could set a stacked label in which one entry was set to English and the other for Metric, and you could then place it as a single label. Take a look at the above example I provided to see these settings personally. As far as mathematical expressions are concerned, I am unsure as to whether one can do this with Text Favorites, but I do know that mathematical expressions are often used within Item Types.
P.S. If anyone has knowledge of the use of mathematical expressions within Text Favorites, please enlighten me and the Community!
