When drawing a line, you have the option to press and hold the mousebutton on a point and pull that out to become a tangent.
However, when you've done so enough, it seems to bug out, thereby making it almost impossible to draw it the right way - See attached picture as an example.
I posted it to autodesk's inventor forum, but couldn't get an answer there.
Anyone knows a fix, or should I pester Autodesk to fix it?
