Lines are non coplanar ??

[Anonymous]

I want to "Fillet" a round angle. If I set the radius and then click the 2 lines then Autocad comes with the message: "Lines are non Coplanar" This problem just started in a drawing i was working in ( 50% were already done by Fillet perfectly ) , I draw only 2D. What am I doing wrong?

That simply means the lines are not on the same Z axis.

There is somewhere in here a set of commands which will set all your objects back to 0 on the Z axis.

To do it with these two lines, select both of them. Right click and choose properties.

If they are polylines. Look for the word "ELEVATION" and change that to 0

If they are lines look for the words "START Z" and "END Z" change both of those to 0

You will now be able to fillet your lines

Is it there a limited number of items to be selected? I selected about 1500 lines and I don't get elevation points x,y,z in the properties table. Few lines are ok.

At the command line type OPTIONS

Choose the SELECTION TAB

Look for the OBJECT LIMIT FOR PROPERTIES PALETTE and OBJECT LIMIT FOR DISPLAY OF GRIPS. Make the numbers bigger.

Thanks for answering but the maximum allowed is still too small. I had it on 25000 and maximum is 32000.

Then select fewer lines perhaps? There is a built-in maximum limit you cannot change.

That's right. So I have to do. I was not sure if it is a limit or my program installation is fault. Thanks.
