Noncoplanar

[bigorange12]

I have 2 polylines that I am trying to fillet (connect) with a radius, but it is telling me both lines are non coplanar. So I checked both polylines and they ar both showing that Z axis is 0. I am using autocad 2011, any help will be greatly appreciated. For your info the flatten command or lisp will not help since they are both set at 0. I've asked around here at the office and everyone is never seen that.

Thanks!

There are several possible reasons for the "noncoplanar" message. First, a question: why call it "z axis" and not "elevation"? Are they 3d polylines?

 

Whatever the z value, it can be less than 0.5 and still show up as 0. Try setting the elevations explicitly to 0.

 

Another possibility is that they were created in different coordinate systems. Even though they appear to be in the same plane relative to the world UCS, one could be a translation from a different UCS into that one. Technically they are in the same plane, but they are not coplanar.

 

If they are 3d polylines, each vertex can have a separate z value, so by definition they can't be coplanar.

 

Out of ideas. Anyone else?

Perhaps, post the drawing..?

 

This may reveal the cause more quickly than our guessing, and the OP reporting back.

Did you try "FLATTEN" or just decide it won't work? CyberAngle might be correct. Your units precision might not be set to a low enough value for your properties to show a non-zero value for the Z axis.

Nope I tried flatten it and still dosent work. Also there is nothing in 3D on the drawing. I cant attach the file, its to big.

Change your view to front so the Z axis is parallel to your view. If they are indeed 2D you shouldn't see anything above or below the X,Y axes.

Do you mean 2 plines as in 2 seperate plines, or 2 segmants of a single pline? If it's 2 seperate plines why not trace over them with a single pline and run your fillet?
