SW2009 - Problem with creating 3D line tangent to helix
SW2009 - Problem with creating 3D line tangent to helix
(OP)
I used to be able to do this in SW2008 but have not been sucessful in 2009. Can anyone advise me what I am doing wrong?
I create a helix.
I then open a 3D sketch, draw a random line. The endpoint is placed on the helix - so far so good.
Now I want to make the line tangent to the helix at that intersection point - it does not let me add the sketch relation.
Ultimately I am after a line perpendicular to the helix, but even in SW2008, it did not let me do that, the best i could do was draw a tangent line, and then draw another line perpendicular to that one. I cant even do that in SW2009.
My old SW2008 files that were converted to 2009 still work. I am trying to create a new one.
Any ideas?
