Area by Closed Polylines

This command will calculate and report the area of single area and multiple area closed polylines. In the case of multiple areas, the user can choose to have the areas totaled (Total Multiple Areas) into a single result or to generate data for each area separately. Area by Closed Polyline will also automatically find special Carlson attributes attached to the polyline, in addition to capturing the area itself. These attributes will appear in the report, which can be the standard report or which can be presented in the Report Formatter, which itself links to Excel and Access. For example, property names and owner names, as applied to a polyline using the Mine modules, will report out automatically using Area by Closed Polyline. The command “Draw Lots from File…” will apply “extended entity data” to the lot polylines, which includes the lot name, and this will also report out when using Area by Closed Polyline. In addition, lot names, or any interior text whatsoever, can be captured and included in the report. The plot of the area on-screen can be canceled if only the report is desired.

Prompts

Select Area Polyline: select the area polyline
SQ. FEET: 64862.9  SQ. YARDS: 7207.0  SQ. MILES: 0.0
ACRES: 1.5  PERIMETER: 1018.7
Pick area label centering point (Enter for none): pick a location

When auto-placing labels at the rear of lots or when aligning labels by the sides of the lot the user will also be prompted to pick one or more centerlines (Select the Centerline Polylines). The routine will find the closest centerline and use this to determine the location of the front and back corners of the area.

When additional interior text is selected, the standard report will include that text:

Polyline Area                    11/17/2004  12:49
Polyline Area: 43560.0 sq ft,  1.00 acres
Polyline Perimeter:  838.35 ft
Text: 16 Sf: 43560.0;  Ac: 1.00

In this case, the “16” refers to Lot 16, and appears in the report because the lot number and existing area labeling were selected along with the polyline for the lot.
