Calculate End Area

This command allows the user to select two polylines representing an existing grade section and a final grade section, and calculate the end area. Or you can also specify and define cut/fill end areas by picking interior points. The area calculated can be drawn at a user specified point. Optionally, the command writes the stations cut and fill to an earthwork (.EW) file that can be printed/displayed by the Edit-Process End Area File command. This command starts with the Calculate End Area dialog.

Horizontal Scale: Specify the horizontal scale of the existing cross section.
Vertical Scale: Specify the vertical scale of the existing cross section.
Station Interval: Only available if Write Results to EW File is toggled on. Allows you to specify the station interval that the station prompting will default to as you select the polyline/sections for computation.
Extend Shorter Ends to Longer: Click or leave blank.
Calculate Unsuitable Areas: When checked, the user will be prompted for polyline(s) or interior point(s) that represent unsuitable material. The areas and/or volumes for the unsuitable material is reported out separately from the overall cut and fill areas and/or volumes for overexcavation consideration.
Define end areas by chooses between picking two polylines or picking inside each end area.
Text Scale: Specify the text size scaler, this value is multiplied by the horizontal scale to determine the final text height.
Decimal Places: Controls the decimals for the cut/fill area labels.
Cut/Fill Prefix/Suffix: Specify prefix and suffix for the cut, fill, and unsuitable labels.
Label Layer: Specify the layer for the cut/fill area labels.
Write Results to EW File: When checked, the results will be written to an earthwork (.EW) file. You may create a new file or choose to append/revise an existing file.

Cut: 12002.965 Fill: 660.272
Pick Point for Label (Enter for none): pick point

Enter the station <0.00> press Enter Pressing Enter selects the default station 0+00. If the station does not exist in the file it will be added. If it does it will be revised.
Select existing polyline: press Enter
Continue moving along automatically to the next station interval and select polylines. Or enter the station values randomly. The command sorts the .EW file regardless. As a result of this sort feature, the user can select stations in any order and they will be arranged in ascending order for proper volume computation.
