shallowest to 39
45 to deepest
any ideas? is there an easy way?
see the attached image, i would need a sum total of the square footage for the CYAN and the GREEN each
Solved! Go to Solution.
Perhaps Murph will sneak in here shortly, but it appears to me that you could use Raster Design to select pixel colors. Believe me, this is as far as I can go.
You can get an area by adding/creating a legend table: elevation. You can find the legend table either in the ribbon tab if you have the surface selected or under the surface menu "Add Legend Table..."
Depending on how your table style is setup, you can add a field for "Surface Range 2D Area". Hope this helps!
Assuming your surface is created and ranges are set, you will next need to set up the table style:
This will populate the "Column Value". You will just need to add a "Header", then edit your table based on how detailed you want to get.
ugh, i am using civil 3d 2012, is it possible we have different dialog boxes? see attached screen shot ... i don't see a "properties" tab as you describe in step 7
In step 6. you will need to click in the empty Column Value box; in there you will see the properties tab.
You will set your elevation ranges, color etc. via the surface properties, under the Analysis tab.
i think i may have figured it out, can someone please tell me how to interpret these numbers? (see attached)
for speaking purposes, number 5 which is 43' to 44', what is the 12,164.09 area????
