pilger Posted April 16, 2014 Posted April 16, 2014 Hey guys, I'm trying to draw a circle passing through a specific point and tangent to a line and a circle. Here's the initial situation: Then I do: And the result is: The intended result would be something like this (done manually and with no precision): As you can see, AutoCAD is drawing the circle on the wrong side. No matter where I try to click to pick the tangents, the result is always the same. The tangent system used in AutoCAD is driving me crazy. Any help would be appreciated. tangent_problem.dwg Quote
rkent Posted April 16, 2014 Posted April 16, 2014 Works here on 2014. Circle, 3p, tan, pick circle, tan, pick line, pick node. Quote
pilger Posted April 16, 2014 Author Posted April 16, 2014 2012 here and no matter the order or where I lick to pick the tans, the circle is always drawn on the right side. I need the left side interferences. Quote
rkent Posted April 16, 2014 Posted April 16, 2014 I just tried it in R2002 and it worked for me there as well. Quote
pilger Posted April 16, 2014 Author Posted April 16, 2014 So is 2012 broken? Are you trying it on the file I sent? Quote
rkent Posted April 16, 2014 Posted April 16, 2014 Oops, I may have misunderstood. You want the circle on the upper left quadrant? There is no solution on that side, it can't be done. If you want it on the right hand side of the line then yes it is working on your drawing. Quote
pilger Posted April 16, 2014 Author Posted April 16, 2014 Yep, need it on the upper left corner. And it actually can be done since I can get pretty close to it using C > TTR. So the circle exists. If AutoCAD can't do it, is there any manual way to do that? P.S.: Scaled the whole deal by 1000x and it works now. Not sure why. But it does. Quote
rkent Posted April 16, 2014 Posted April 16, 2014 What radius are you supplying and where did you get that value? Quote
JD Mather Posted April 16, 2014 Posted April 16, 2014 Did 2012 have Geometry Constraints? (not to be confused with osnaps) Quote
pilger Posted April 16, 2014 Author Posted April 16, 2014 It has, indeed. I saw your replies on other threads with similar subjects but I couldn't find any good tutorial on how to use constrains. I was interested though. Could you point me some material for a beginner on the subject? Quote
