CC7125 Posted August 16, 2007 Posted August 16, 2007 Pardon my terminology, as I'm only a day into drafting and the like. Alright, I'm stumped. What seemed to me as a problem that should be simply solved; I've instead hit a brick wall. I'm sure I've missed something obvious. Anyway: What I want is a triangle with the following: Side A: 50 units B: 94.8 units C: 60.25 units The problem is that when I go to adjust the length of one side (B) (via the route in the diagram), it will readjust the length of side C; and vice-versa when adjusting side C. Is there possibly a way I can "lock in" the length, so it will hold? Is there any other way that I've missed in the countless tutorials I've gone through? Any and all help is greatly appreciated.

ReMark Posted August 16, 2007 Posted August 16, 2007 What command(s) are you using to modify the line? Quote
CC7125 Posted August 16, 2007 Author Posted August 16, 2007 STRETCH - I'm using grip edit, and the dynamic input. Quote
ReMark Posted August 16, 2007 Posted August 16, 2007 I thought so. I don't think you can "lock" the length of the line(s). You could put two of the three lines on a different layer and then "lock" that layer. Would that do? Quote
eldon Posted August 16, 2007 Posted August 16, 2007 I can't imagine a more clumsy way to form a triangle of known side lengths. If you want a sure fire way of "locking" the lengths, draw a circle with a radius of the side. By drawing the circle from the upper point of line A of radius 94.8 units, and a circle from the lower point of line A of radius 60.25 units, you can then STRETCH the apex to the intersection of the circles Quote
CC7125 Posted August 16, 2007 Author Posted August 16, 2007 I don't think so. If I were to lock it, it would need to just lock the length. I need the angles to be able to change and the sides of the triangle to not lengthen/shorten when adjusting an adjacent side. Basically, I just want a triangle with the dimensions I gave in my first post. If there's another way to do it, I'm all ears (eyes?). If it's of any help, here's a diagram of what I'm trying to plot out, to give a better idea of what I'm trying to do. Points 1, 2, and 3 are what I'm working on currently. The only information I have to plot it out is distances between points, so triangles seemed logical. Apologies if this is getting a too off-topic from my original post. Quote
CC7125 Posted August 16, 2007 Author Posted August 16, 2007 I'll give that a shot eldon. Thank you. That should do the trick. Quote
freeko Posted February 5, 2009 Posted February 5, 2009 make circle from 3 wirh R=60.25 make circle from 3 with R=94.80 draw radius line of the biggest one (R=94.80) from the line intersection with biggest circle draw circle with R=50 then you have all triangle points Quote
Tiger Posted February 5, 2009 Posted February 5, 2009 If you've solved the problem, feel free to ignore my post If you use the command LINE (instead of PLINE that I believe you have used in the first post) and do three lines of the proper length (feel free to do them different colors, it will help ) you can then move them around and connect them in one point first and then use the command ROTATE to get the complete triangle. Since they are Lines, and therefor seperate entities, if you change the length of one, the rest won't change Quote
dbroada Posted February 5, 2009 Posted February 5, 2009 I think as the OP has only posted 4 times in the last year and a half, and all on the same day - he has either found a way or is no longer bothered. Quote

chulse Posted February 5, 2009 Posted February 5, 2009 It would be nice if folks always posted back when they find a solution... Quote
dbroada Posted February 5, 2009 Posted February 5, 2009 or even if they don't. I've lost count of the number of times you offer advice and are left wondering if it helped or not. (Not aimed at you Cary - I know we never finished your tree ) Quote

(Not aimed at you Cary - I know we never finished your tree ) Ha! - That's still a work in progress. I do have a functional version in production now though, but I just keep fussing with it... Do you want to see the latest? Quote
dbroada Posted February 5, 2009 Posted February 5, 2009 Do you want to see the latest?I'd be interested - but I'm so busy atm I'm not sure I could spend long admiring it. Quote
CC7125 Posted February 5, 2009 Author Posted February 5, 2009 My apologies eldon's suggestion did the trick for me. I had been expecting things to work a little differently than they do. I was thinking more along the lines of Computer-Automated-Drafting/Design, instead of Computer-Aided. If you understand what I mean. Overthinking the problem, I guess. Again, sorry for not following up sooner. Quote
