Ruby - Area of Ployline

[ComputerMaster86]

Would some be willing to tell me what the ruby code is for working with area of a polyline?

 

internal_area <-- I don't believe this is it.

 

Thank you all in advanced.

Well I am trying to round the area two to decimal places.

[ComputerMaster86]

I can't seam to get area.round(2) to work.  I wonder if I need to name the macro a special name?

[Joe_Carrick]

Create a new macro named "Area.rounded"

• Check "Evaluated"
• Select Context "Owner"

enter the following in the macro

• result = area.round(2).to_s

insert that macro in the Polyline Label.

Thank you all so much.  I feel like my next steel re-roof job is going to be ten times easier once I set up all of my macros.

Joe: Is the string conversion really needed, or just the proper way to do it -- like explicitly assigning a value to result.

Eric,

 

I do that so the it's easy to add (concatenate) the result.

example:

• result = area.round(2).to_s + " sq.ft."
• result = "Area = " + result

or, if you want to perform some other calculations:

• x = area.round(2)
• result = "Area = " + x.to_s + " sq.ft."

There are other ways of coding to get the same result.
