Recently, when I draw a vertical line off of a plan, to align a section above it, and try to use the fillet or move command, I get a message saying, "lines are non-coplanar."  However, I am able to use the vertical line to trim the horizontal line.  Any thoughts?

Try to select the lines , and then search for the "elevation" ,"level in Z" or "start in Z" and "end in Z" in the properties palette, and set it to Zero. Let me know if this helped you.

 I don't understand the relevance of this to Moving.  Am I missing something? Trimming can use the apparent intersection if things are not co-planar, but Filleting requires them to be in the same plane.    

If you don't care that the lines are non-coplanar then ignore the warning.  It all depends on what you are ultimately going to do with the lines.

 Clearly they are (at least sometimes, but see my earlier Reply) going to Fillet them, in which case they would care, and the need would be to overcome the warning, which can be done only by getting them to be coplanar, in ways already suggested.

Apparently the OP is unaware of the abilities or lack thereof of the Fillet command.  Now he knows.

Yes John, when lines are non-coplanar you can trim them at "0" but not fillet them.I use this in 3D and it is working with the UCS setting.When you trim 2 non-coplanar lines the distance that you get is X=0 , Y=0 and Z different from zero.You can use this for example to draw the maximum box around a 3D solid or draw a cut on elevation lines at different Z.

I'm aware of that.  The OP isn't.

Sure thing Tonto.  How much do you want?  A hundred?  One thousand?  A million?  I have coin to spare.  Just leave your full name, address, cell number, bank account numbers and where you work.  I'll get the Bitcoin to you as soon as you do.
