would it be possible to have a Tangent to isometric command.
very much like the tangent to orthogonal but along the 30/210, 150/330 (and 90/270) degree axes.
when drawing in isometric and wanting a line from an ellipse or any curve, it would be handy to lock onto a curve and find the perpendicular to an isometric line. Great for creating cylinders in isometric
I would keep the isometric tangent command enabled all the time (not when the isometric grid only is on)
