Pulling a Curve
When you select a curve with the Pull tool, the direction of the extrusion is determined by the plane of the curve.
| The default direction to pull a curve is along the Z axis. |  |
| If a curve lies on the Z axis, the pull arrow points in the Y direction. |  |
| If you select two curves on the same plane, the pull arrow points in the direction that is perpendicular to the plane of the curves. |  |
| If you select a curve that touches another curve, the pull arrow points in the direction perpendicular to the plane of the two curves. |  |
