Hi - I want to write a little lisp routine to set the leader arrowhead to "Closed filled" for dimstyles in the current drawing. As you might imagine, this is to fix drawings that have made a round trip to R14 (and back to 2002 or above). I can handle finding the names of the dimstyles I want to change and looping through them. But I'm thinking activex is the best way to actually make the change to each dimstyle. Unfortunately I haven't learned to use activex yet. Can someone spare me a couple lines of activex code? Thanks - Chuck
