How can I retrieve both coordinates for a dimension including the angle of the extension line? (I'm using Linear, Aligned and Arc Length dimensions). I want to build a lisp that cycles through all the dimensions in the drawing and inserts a new block at the dimension coordinates using the extension line as the angle for the insert. David

Good day, This is my first post after hours of searching. I have bits and pieces related to my question, but nothing substantial. I have a database with ~350 computer's physical coordinates within the building (actually not yet, but a field to fill) and all related info for that computer. Is it possible to have an object for each computer, and have that object's coordinates within the drawing updated when the database is updated? Or anything that can help with IT's management of these assets? The long-term goal is to have the maintenace people to be able to see where an asset(computer) is physically within the building. We will soon be using HP Service Manager 7 which utilizes a database with said information. I apologize if this is in the wrong thread. I have only fiddled with AutoCAD and am now jumping in head-first. I have only about 30 days to figure this out. Thanks!!! (patience with the Noob )

I just want to start out by saying I know a little bit about cad but I do not know a whole lot about plotting corrdinates. My issue is as follows. I have about 40 gps corrdinates that I took with Droid2Cad which are recorded as lat, long, and alt. The points can be exported to .dxf and .kml(google earth). I have exported them to both and it looks like google earth plots them correct but I have issues with the .dxf file. I have a .dwg site plan of an agriculture site from a engineering firm that seems to be drawn at 1:1. When I go to overlay the points on the site plan the points end up way off off the site plan. I dont know if I need to scale the .dxf or what. The points seem to be in the right configuration but they dont land anywhere close to the right spots. When I overlayed the points on the .dwg, I selected all the points, copied with a base point on a point that I knew the corresponding point on the .dwg, and pasted that point to the point on the .dwg. I dont know if I did a good enough job explaining this but I would appreciate any help anyone can give me. If you need more info or clarification please let me know. Thank you for your time.
