Thanks @hefniraera !

Are you planning to include Bézier curves in this PR as well, or do you want to create a separate one for that?

I was wondering if you're going to open a PR related to Bezier curve as you mentioned here. Could you also please clarify what the 'Weight' represents? Thank you.

If you want, I can write a short paragraph about Bézier right here.

As for the weight, it’s important to know that there’s a map tool shortcut associated with the W key + mouse wheel (Ctrl modifier: fine adjustment / Shift modifier: coarse adjustment ) that lets you move closer to or farther from a control point. This determines the weight. If a point has a higher weight, the curve will be pulled more toward that point than if it has a lower weight.

That helps. Let me try on my side. Thanks

NURBS control points and degree, allowing precise control over the curve shape.
NURBS degree controls the shape of the curve. Higher values make the curve smoother
and more flexible, while lower values create simpler curves.

The selected technique remains while switching among the digitizing tools.
You can combine any of the first three methods while drawing the same geometry.
