Rohaya Shaffini of Stats ChipPAC Ltd. requested a routine to add circles and sequence numbers to a schematic of a rectangular integrated circuit chip drawing (see a typical schematic below). Rohaya requested that the circles be offset by an amount selected by the user. Plus, he wanted to indicate the start location for numbering, the circle radius and a choice of clockwise or counterclockwise numbering direction.

The solution is TIP-NUM.LSP that lets you select all of the tips surrounding the main rectangle by using a window. You select the upper-left point first and then choose the lower-right point.The program then asks for the start point for the number sequence, the number direction (clockwise or counterclockwise), the offset distance from the tip to the circle and the circle radius.

Get the Code
Download the TIP-NUM.LSP file from our Get the Code! area and save it in AutoCAD's Support directory. Use the Appload facility by selecting Tools / Load Application and then select the TIP-NUM.LSP file from where you stored it.
