Control Points
When you draw something in Giraffe, you will notice each corner has a small white "dot" outlined in Red.
The corner dots are known as "control points."
Click and drag a control point to move it
Click and release a control point to remove it.
Midpoints
You can also see a transparent red dot at the center of each edge. This is called a "midpoint."
Click a midpoint to add another control point.
A new midpoint generates at the center of the new edges.
Extruding Edges
A straight section of a geometry is called an "edge."
Control points are connected by edges. Midpoints are at the center of edges.
Each edge has 2 handles that look like small arrows. There is one handle on each side of the midpoint.
Click and drag a handle on an edge to extrude that edge.
Extrusion is always parallel to the original edge.
