You need to click twice: the point you want to label and label location. You should be able to use it after you load the program. I wrote the code to run when I type LB then enter.

Once you've built the code, simply run the 'LD' command, and select two points defining your leader (the code can easily be extended to allow selection of additional points and entry of a user-defined annotation string, of course). There are several ways to load AutoLISP program, but this is the easiest way. Then we simply have to get its ID and return it. To make sure this block exists, the function sets the value of DIMBLK to the arrowhead name, which - assuming the name is valid - will create the block in the block table. Block Inserts a block at the end of the leader line. Blocks or feature control frames with geometric tolerances are attached to the end of the leader line. ObjectId arrId = GetArrowObjectId(arrowName) Ī helper function (GetArrowObjectId(arrowName)) is used to get the ObjectID of the block of our arrow head. The value of the current text gap (see DIMSTYLE or the DIMGAP system variable) determines where the text and multiline text objects are inserted.
