Forget that problem bend for a minute.
First you need to get these two arcs created in the 3D sketch (if 2011 had the tool for 3Point arc).
Otherwise it is going to have to be done with intersecting projected curves similar to my Knot tutorial.
IV2011 does have that tool...I have previously drawn non-projected arcs as per your marked up sketch...
at this point (having gave up) I have sketched an arc on one line as per your red aroow on your sketch...
Then I've tried sketching in an arc between the newly added line and the angled line...(crossed out 75 rad) but I can't tangent this new arc to anything...
it allows me to select one line but not a second line...
I just cannot draw an arc in 3D sketches...and I've tried all your suggestions before you suggested them...
so I'm lacking something that you have...
at this point (having gave up) I have sketched an arc on one line
You are not following my instructions.
I did not draw an arc on any line.
Have you given up or should I elaborate the instructions?
Note these points in Sketch2 (don't really need them but it will help visualize the placement of the 2 3D arcs (forget the problem arc for now). Note that these points are on arcs - not on a line.
They are the endpoints and midpoints of two arcs in Sketch2.
I don't see the points in your image that are in my image?
Attach your latest attempt here. (I am really onluy interested in Sketch2 at this point.)
Note that the lines are green because I can't constrain them to anything...
IV2011 won't let me...I've tried everything...
ps. I'm about to go home so I'll check your reply in the am...
I don't understand what you are doing.
It looks like you are trying to get ahead of the horse.
Your Sketch2 doesn't look like my Sketch2 (you didn't change to construction and add the sketch points)?
I said to forget the problem bend for now, yet you already have a Sweep and for some reason a Move Face?
Let's set up Sketch2 first and keep this simple. Change everything in Sketch2 to construction and add sketch points at the ends and midpoints of those two curves.
(delete the Move Face and Sweep, but not anything else)
Note that the lines are green because
Where did I instruct to create any lines?
If you follow my instructions step-by-step the 3D sketch will be fully constrained and trivially easy to create.
But I don't generally reveal the next step until I am sure the previous step is fully understood.
