The only other option, like I said is that the line is tangent to some point on the circle.  That is the only option that makes sense.  Anything else and your geometry will be wrong and while that may not seem like such a big deal now (barely see the error) it would make one hell of a difference if you try to JOIN the two lines or create a 3D model.  Errors like that will screw things up quicker that a fox running in front of a dirt bike.

Common "points" on a circle would be the center and the four quadrants.  These can be "grabbed" with the aid of your osnaps.  After that you're probably looking at lines that are tangent (another osnap option) to some part of the circle.  This will vary depending on where your line starts to begin with.  Is that clear as mud?

The cookies look awesome.  Smell awesome and taste....  Well let's just say that it borders on insanely good.  And washed down with a very cold glass of milk....it's heavenly.

Why do dirt bikers climb hills?  Because they're there.  That's all the excuse we needed.

Honestly I don't mind helping you at all.  If you have a question come back and post.  Can't promise an instant response but I do check this particular website fairly often.

Good luck with your drawings.

Got to sign off for a while so I can actually get the cookies baked without burning them.  It's got to be about 5 p.m. where you are right?  Have a good evening.  I'll catch up with your down the road at some point.  Keep smiling.

Adios amigos.

No problem, I appreciate it. All I want to know is have I done it correctly. Then I can move on to my next drawing. At the moment I am a little, as the Pilots phrase goes, 'behind the curve' with my college drawings and I am trying to catch up. We are on drawing 9 at the moment so I am trying to go through them all again to refresh my memory...that's where this forum comes in and I hate to put the pressure squarely on you, you see. I feel guilty as hell.

Your description of what you used to do on your bike sounded wonderful, you have described how most of us feel and it is a good description of why we love it!!

PS- Quick story- I used to have a little Yamaha DT 50 when I first started when I was 16 and I tried and tried and tried to get up this steep dirt track which lead to the top of a mountain but never could quite get there (I tried running alongside it and everything, used to get so hot and bothered). The joy I felt when I got a DT 125 and finally made it was something else, I will never forget that! It turns out there wasn't a lot up there...but that's not the point!
