Tipster Timothy J. Harlow discusses a method he uses to count parking spaces for his projects in AutoCAD.
"This is a routine I use to determine the number of parking spaces on a site. Start by creating a drawing containing a donut with a radius of 1 (units=feet) and placed on layer 0, color byblock. The base point of the drawing is 4.5,0,0. Save this drawing in a easily located folder, giving it an easy name such as PD.
"Next, create a toolbar with the following routine within the CUI: *^C^C^Cme;;pd;;9;. Make a button for each anticipated stall width. Create a layer, such as Parking Count, into the site drawing, then insert the block.
"Next, offset the curb or pavement line adjacent to the stalls by a distance of nine feet. Click the button and pick near the end of the offset line. For total spaces, use the command SXX, then select one of the instances of the block."
Notes from Cadalyst tip reviewer Brian Benton: It's amazing how difficult it can be to count parking places. This tipster's method may sound complicated, but it works. The tipster creates a block file (PD) and inserts it into the drawing. A new command is created that will insert this block every 9 feet (or whatever distance you want) along an object (line, polyline, etc.) using the Measure command. Then the filter selection set (SSX) counts all instances of that block in the file, giving you a total that correlates to the number of parking spaces. I have also seen users create a block and insert it into each parking space manually, then use BCOUNT to count every instance of the block. This tip is very similar, but it automates the block insertion process.
