Suppose I have a curve whose ends points have arbitrary normals as in not X,Y,Z.. Whats the best way to exactly get a profile shape like an ellipse for example to be snapped directly onto that point to be swept or extruded along path?

I know I can look at the profile from the plan, elevation or end view and rotate it accordingly, but there must be an better method..

Hi,

First, show the workplane (workplane- show workplane). Select the curve, then move the cursor over the end of the curve you want to place the circle(or shape) and you will see the cursor snap to the end position, then press the "C" key. The workplane will move to that endpoint.

I have attached a vid to show.

You will see the workplane suddenly move, that is when I have pressed the "C" key

The vid is in xvid format


Workplane move

Yes, it can save time.
You do need to be cautious, as if you press the "C" key again, the workplane will move, it will toggle between various orientations. So it is good practice to just visually check that the arrow, which shows the positive Z direction, is actually pointing in the correct direction.
You can then, if wanted, go to "view- view the plane" to get an ortho view looking down on the new workplane.

what a "lofty" tutorial. :D
