Title: a bug in Area between polylines
Post by: tvargek on March 28, 2025, 08:28:38 AM

I think there is a bug in calculation of cut and fill area between polylines. For test, if you draw two parallel polylines of equal length and do a cut-fill area measurement, it wont be the same as if you connect their ends and do a closed polyline area measurement, and it should be the same, unless cut-fill area mean something else then what it usually is.

Hi,

Thank you for making me aware of the bug. There seems to be something strange when doing what you describe. I will investigate the matter and fix the error.

Hi,

This problem is due to proposed surface line "hovering" above the existing ground. This should not be possible in the "real world". However this can be true if you have clipped cros-section windows.
I will change this behavior so it also can calculate proposed surfaces that does not have contact with existing ground.

This will be fixed in next update, I'll post in this thread when it is available.

This is now fixed in update 767

"Fixed unwanted behavior when surface line and proposed does not intersect. Added setting for display (plot) area figures in drawing."

Please read helpfile for more info about new behavior.
