Hold ⌃ Ctrl + ⇧ Shift to straighten the current segment. Switch from a smooth curve to a straight line Press to place the point, and without releasing the mouse button, move to drag out tangent handles. In Draw mode, click or drag in empty space to start a new curve, or click/drag an the start or end point of an existing curve to continue drawing the curve. However, when you are drawing these other types, you simply click to place each point, and Houdini interprets the point according to the curve type, without the special support for drawing tangents you get when drawing cubic Bézier curves. You can also use this node to draw polylines, non-cubic orders of Bézier curves, and NURBS. These corners remain editable while you use the node, then are “baked” into the curves. You can set corners as rounded, and control the radius of each corner with a draggable grip. This node also includes an “Auto-Bézier” mode, similar to Illustrator’s Curvature tool, which lets you “guide” a curve by placing edit points, without having to worry about tangents. (Technically the arcs are not perfectly round, because this node does not create weighted Bézier curves.) While drawing a Bézier curve, you can insert arc segments. For example, tracing images, drawing logos, drawing profile curves to extrude, revolve, and so on.
This is very useful for drawing “artistic” curves by hand. This node’s interactive state lets you draw and edit cubic Bézier curves using tools similar to 2D illustration programs like Illustrator, Sketch, and InkScape.
