Question
How can I move a non planar line at(i.e x=10,y=4,z =23
to a line on x=10,y=4,z=0)
I have two lines wich are not intersected, in different plans and i want both to be at the same plan.


Answer
Munir:
Lines have two main points:  A starting point and an endpoint.  Each point has one set of three coordinates: x, y, and z.  But each of the lines you depict is showing only one point.  The two sets of coordinates can be drawn as ONE line:  Thus:
Command: line
Specify first point:10,4,0

Specify next point or [Undo]: 10,4,23

Specify next point or [Undo]:

If your plan view coincides with the current UCS, your line will look like a little dot, because only the Z coordinate is different.  But if you use _3DORBIT or _VPOINT you should be able to rotate your axes so that you can actually see the line.

So, if you want to draw a new line at the top of the original line, you can draw it with these or similar coorindates:

Command: line
Specify first point:10,4,23

Specify next point or [Undo]: 20,8,23

Specify next point or [Undo]:

That new line will be perpendicular to the original line and will be at a 90 degree angle to the first line.
