Quick Area (Tip #1972) from Bryan Bobrick provides a quick answer to the question: What is the area of that object? After the LSP file is loaded, start the Quickarea command. The function prompts you to select a closed object such as a circle or a polyline. After you select the object, the routine executes the Area command and shows the value in the AREA system variable. Quickarea displays the value from the system as square feet and other units of measure, although you may be using different units. This function is a great example of how to exploit information inside AutoCAD with AutoLISP.
