How can I measure the area of an irregular work piece in AutoCAD 2007?
From contributor D:
Area is a property of AcDbPolyline. If you convert your entities to polylines, then join them using the pedit command, you can retrieve the area by using the list command or via lisp.
(defun c:getarea ()
(vla-get-area (vlax-ename->vla-object (car (entsel))))
Just hatch each area type with a different hatch pattern. From there you can select each area or even groups and use the properties tool to get the square inches, etc. This thread reminded me of drafting that project.
2. Drag the .pdf file of the site plan into AutoCADís Model viewing page.
3. For the following prompts use:
a. 1 for page number
b. 0 for intersection point
c. # of feet per inch complimenting scale on plan (example: type 20 for 1Ē=20í)
d. 0 for rotation
4. Right click on the screen, select Zoom.
5. Right click again on the screen, select Zoom Extents. Press Esc.
6. Zoom in and out of the site plan with the scroll up/down on the mouse. Pan around site plan by holding down scroll button on mouse and moving mouse to desired direction.
7. Under Home tab on top of screen, select Polyline tool under Draw section.
8. Starting at a corner, go around the edge of either the earth disturbance line or site limit line and left click on the mouse to make a point. If you plot a point you didnít mean to, just hit control + z to go back one point.
9. When getting close to the end of completing the enclosed object, type c or close to finish and press Esc.
10. By selecting the object just created you can move the points around to be more exact.
11. Type area in the command window, enter o for object, and select enclosed object. Area and perimeter reading will appear in command output box.
