Drawing lines in 3D

Hi!

I have a few question regarding drawing lines in 3d space.

I first tried drawing a 3d line using the PLINE command. I entered values using @50,0,50 but it didnt allow me to draw the line in 3D.

Then I used the LINE command and used the same procedure it worked just fine.

From this I concluded eventhou you can enter values for x,y,z, for PLINE command, the comamnd it self is intended only for 2D operations.

On the other hand LINE worked very well :-)

I found that I also have 3D polyline wich can draw the line geometry in 3D space but the problem here is that I dont have arc suboption available while drawing geometry :-(

My question is, is it possible that after you draw a eg. polyline wich has also arc segments in it, is it possible to grab its grip and drag it in z direction?

One option: 3Drotate.
