I'm trying to write a Lisp that will change all of the dimensions settings in an open drawing. My company used to use arrow heads (Closed filled) for all their dimensions and would like to switch to using Architectural tick marks. The problem is that when we are using a drawing of something we have created in the past, all of the dimensions have arrows and we have to manually change all of the dimension's arrows, one by one, to arch ticks. I know there is a way to do this in Lisp, I just haven't been able to find it on the web. Any help would be greatly appreciated!
Thank You,
