|Most functions are very straight forward. The only ones that might be tricky are the quadcurve and cubic curve tools. First some definitions: |
QuadCurve has a total of three points (2 endpoints, 1 control point)
CubicCurve has a total of four points (2 endpoints, 2 control points)
Endpoints define where the line starts and stops. (Placed with left mouse button)
Control points determine the curvature of the line segment. (Placed with right mouse button)
To set an endpoint press (and hold) the left mouse button down, then move the mouse to a new location; release the left mouse button to set the other endpoint (and draw the line segment). To set the a control point press (and hold) the right mouse button down, move the mouse to a new location; release the right mouse button to set the second control point. The line is always drawn as soon as you release the left mouse button, so set all your points before you release the left mouse button.
