Element Is Slightly Off Axis

Warning: Element is slightly off axis and may cause inaccuracies.

Issue: This warning is triggered by elements based on lines that are misaligned —by 1x(10^-9) to .2 degrees— in either the horizontal or vertical directions, or with a line at 45 degrees to the horizontal/vertical direction.

The problem can be caused by sketching or rotating elements when angle snaps are turned off, or it can result from pre-existing elements when you do any of the following:

Off-axis problems need to be resolved, because Revit cannot create dimensions between lines that are not exactly parallel, and cannot join or cut geometry if faces are slightly off-parallel or have very small gaps due to off-axis elements.

Solution: Depending on the cause of the problem, do one of the following:
