I have inserted a plane in a 3D sketch and offset it from a face.
After sketching the feature and centerline and exiting the sketch command I'm prompted that the selected centerline is invalid.
I've noticed that the direction arrow is parallel to the plane unlike when creating a revolved feature that was sketched directly on a plane (the arrow points "normal to" the plane).
I'm new to SW and figure I must be going about this the wrong way.
