Resolve "Lines are non coplanar" Issue

To resolve the dreaded "Lines are non coplaner" issue using the fillet or trim command you need to convert all lines to have a "Z" coordinates of 0. Here are the steps:

• Select all objects in your drawing (hint: use Ctrl A).
• Start the Properties palette (hint: use Ctrl 1).
• Press Now we can filter out just the lines by pressing the QSelect button on the Properties palette:

• Set the object filter to Lines and press OK (this will filter out everything but the lines)

• Now in the Properties palette set the Start Z and End Z to 0



Now your lines should be flat and ready for trimming.
