Parallel Line drawing tool/command

Hello all,

I made a closed curve (in this example a simple s curve) but I would like to increase the width without scaling the entire size up. Is there a tool that can redraw or trace the curve while adding an increase in width? I imagine it would have to constantly be perpendicular to the original curve.

In the examples I roughly added a bunch of lines 5 cm in length that come out perpendicular from the original curve. This way, the other curve has a path to follow, but I was sondering if there is a tool that does this automatically as the is an example and the actual project is far more complicated

Hello - use Offset for this, Cap=Flat.
