I am needing calculate the top of pipe under a road way to the bottom of the sub grade minus 6".  I understand how to get the smart text to give me the elevation of the to object and how to use the math function to offset the bottom of SG and how to offset the FL of the pipe to top of pipe and it will show the two elevations.  But i swear I saw on a demo somewhere and I can't seem to find it that it would calculate the depth then for you as well.  Can someone please show me how you do this?

Thanks,

Ben

Hi Ben,

Thanks for posting that! I have the same question.

I'd love to know how to combine two smart texts to show depth... or slope... (depth/distance).

Cheers,

Depth to Invert = @<ELS,L,F,2,T>@
Depth to Crown = @<ELS,L,F,2,T|+0.5>@

This is what you do if you want to add 0.5' to the Invert to get to Crown of Pipe to get real depth of cover

Is it possible to use something more than "Simple Math" ?

Like: @<ELS,L,F,2,T> + <ELS,L,F,2,T>@

instead of: @<ELS,L,F,2,T|*2>@

I dont think that will be possible as that would require you to select a line 2x and the UI is not designed to do that

Alan

Alan, what would I need to do to subtract a point elevation which is subgrade from a surface elevation at a location to give a delta value?

Do the same as I did for the invert ie add the subgrade depth to the line elevation and if you want subgrade plus pipe crown then add the invert to crown distance to the subgrade depth to compute the depth from subgrade to crown

This assumes that the subgrade depth is constant - if not then you would need to reference the subgrade surface not the design surface to get the depth of cover

Alan, in the example below I'm grabbing finish grade from the surface model and existing grade from the point data. What smart text equation would I use to subtract EXSG from FG and display as a delta value (DEL=)? 

Thanks in advance,

Tom

The Smart Text you need is as follows

Elv: @<EL,O,F,2>@
DElv: @<ELS,O,F,2,T,T>@

The Elevation is of the Point and the DElv is the Cut Fill from the Point to the referenced surface.

You can also do Mass Labeling of a lot of points using the Label Points command if you define a Label Style to do it - you have to have a different style for labels that reference different surfaces - here is the UI of the Label Style Editor for such a point label

Alan

Alan, the mass labeling was the ticket. There is so much functionality in TBC that i don't use on a daily basis. I appreciate you taking the time to help us out!

Hey no problem Tom - I always wanted to be the "Oracle"

Thank you Alan.  This really is a powerful tool I will need to start getting more comfortable with in the creation of plan sets.

Thanks Again,

Ben
