TimZilla Posted May 3, 2010 Posted May 3, 2010 This is hard to explain so I have an attachment here for you to see it, but here is the explanation: I am not sure if autoCAD does this, or a lisp has to be made. Say you have 3 lines coming together forming a sideways tee. If I move one line, the break points follow, ohh heck, just look at the attachment! lol move line, break point followsl.pdf you might have to rotate the PDF view counterclockwise so you don't have to look at it with your head sideways Quote
Lee Mac Posted May 3, 2010 Posted May 3, 2010 Sounds like it would need a reactor to update the positions of the other lines. Quote
TimZilla Posted May 3, 2010 Author Posted May 3, 2010 aww man, so this would be a hard one? dagnabit! I hate having to highlight those other two lines and snap them to it. I am sure there is some piping company out there who has made it because after we survey the building, we do a lot of shifting. It takes forever! Quote
Lee Mac Posted May 3, 2010 Posted May 3, 2010 Its do-able, but difficult, yes. It would depend on how advanced you'd want to make it, but I could visualise using an Object Reactor to react upon modification of any of the three lines, and the parameter/handle at which the line was 'attached' would have to be stored in perhaps the xData of the object - like I do here. But, using an object reactor that depends on multiple objects - one of which is being modified by the reaction - is difficult, as you have to prevent a recursive reactor call by temporarily deactivating the object reactor during the callback, and perhaps creating an instance of a command reactor to react after the object modification and prevent a recursive call to the object reactor. This method is described here... (yes, I've been down that road..) So, all in all, as far as I can see (which may not be too far), the difficulty in coding outweighs the gain. Lee Quote

Lee Mac Posted May 3, 2010 Posted May 3, 2010 Didn't you learn anything in Physical Education? :wink: Don't forget to Stretch. My CAD ignorance and devotion to programming reveals itself yet again... very nice Alan. Quote
alanjt Posted May 3, 2010 Posted May 3, 2010 My CAD ignorance and devotion to programming reveals itself yet again... very nice Alan. No worries. Once in a while, I'll write some code only to then remember that a close-enough-command exists. I just facepalm and go on with my day. I was just hoping you'd read it before cutting a bunch of code.

TimZilla Posted May 3, 2010 Author Posted May 3, 2010 Ya know what, I have never figured out that stupid command, I took it off of my toolbar. I thought that it made a square look like a triangle! STRETCH! know what i mean? so now that I know it does that! I shall try it! Quote
Lee Mac Posted May 3, 2010 Posted May 3, 2010 I thought that was the stuff they taught you when you become a CAD Drafter - I've never gone for the qualification personally. Quote
TimZilla Posted May 3, 2010 Author Posted May 3, 2010 I doubt you'll be wanting to mention this thread to your boss then... lol, im the only CAD junky here. They just do there job and go home. I do share Lisps with them if they benefit what we do. I took a 80 AutoCAD course to be qualified for what we do (as far as drawing). Drawing is the easy part of this job, the water calculations, and following these code books that stack a mile high is the hard part. Quote
TimZilla Posted May 3, 2010 Author Posted May 3, 2010 Look, I don't care what people say, I would guarantee, there are a lot of people trying out that stretch command now. Because they probably didn't know either! I still think it could be improved. just allowing you to click on that one line and moving it bringing everything with it. ya know, because highlighting the whole line is too hard! Quote
