   hello, im pretty new to AutoCAD and i have been teaching myself how to draft as efficiently as possible via Youtube and forums such as this (this one is my favorite). Whoever, today i couldn't find the answer to my question online so i thought i would ask about it on here.

When drawing floor plans, roof plans, floor framing plans, ect. I have to draw in a lot of different size headers above openings. i started out by just drawing them all then going back and extending the line endpoints 1.5-3 inches past the respective openings but that takes too long. So i figured out i could use the LENGTHEN command on DELTA and just go back through and click the end points to extend them the correct amount. 

-----What i would like to do is just draw a line and have it automatically extend itself past the beginning and end points i select to a predetermined length. is this possible? 

thanks,
Ryan

	Why didn't you use the TRIM, EXTEND or FILLET commands? Did you look at the MLINE (MultiLine) command? Or did you consider using SNAP and GRID? Do you also make use of OSnaps? There is no feature like you describe in AutoCAD. Edited by John Connor - 05.Mar.2014 at 23:47

	thanks for the quick response time John Connor, i thought i could count on you. yes, i have tried using the tools you listed below, except for FILLET, which i don't know how i use to get the effect i want. i'm curious as to how you would suggest i do so if you don't mind elaborating. i tried using OFFSET to get the correct distance of header over hang and then TRIM back to it. when you do this you have to go back and erase the original offset line though. i guess i could offset to a non-printing layer though.. that's to bad that such a tool doesn't exist. i was hoping it would, if you have any other suggestions that would be great, thanks, ryan

	Post an image so I can narrow down the choices. What about the STRETCH command? No trimming and no extending.

	Are you talking about the dashed line that overruns the two small solid lines like where a window or door might be located? You're having a problem drawing those?? OK...the solution is to make the header a dynamic block with a stretch option. Edited by John Connor - 06.Mar.2014 at 00:53

	yep, the dashed lines are the "headers" of which i speak. i wouldn't say im "having trouble" drawing them, i just don't want to waste time drawing each one. Remember, im aiming for efficiency. that sounds like a great solution. i'll have to look up how to do that. thanks John

	Have you used TRIM with Select All (in other words, type TRIM at the command line. Then when prompted for what to use as trimming lines simply hit the <enter> key. This selects everything in the drawing. From there you can jump throughout the drawing trimming everything you need to. This idea allows you to very quickly draw without worrying about getting everything correct... just make sure the lines are longer than they need to and cross other lines. Then go back and trim later. Dave.

	Check out the BeamLineLabel.lsp routine here: http://forums.autodesk.com/t5/Visual-LISP-AutoLISP-and-General/Lisp-Request-Pline-Beams/m-p/4762867/highlight/true#M318626 That makes Polylines with width, because that's what the poster was looking for. I also have one that makes Lines instead, if you prefer.

	I suggest to modify the "acad.pgp" file and tailor it according to your convenience. You can modify the shortcut keys to suit to your left hand's convenience. Example. D, DIMLINEAR DD, DIMALIGNED DDD, *DIMANGULAR
