Click and drag in the viewport to draw with the Pencil.
Stroke Width - set the width of the Stroke.
Cap Style - set the appearance of caps (each end of the stroke) for open paths.
Flat - a flat end that terminates at the end point.
Round - a hemispherical end with the end point at its centre.
Projecting - a flat end that projects half the Width beyond the end point.
Accuracy - determine how closely your resulting shape resembles your cursor movements. A higher setting will result in a more accurate shape but will create more points.
Close Distance - if you end your line within this value of the start a closed path will be created. Note - this value is independent of the Viewport scale.
We've started work on a redraw feature which allows you to redraw pencil paths. To try it out:
Draw an open path with the Pencil.
r and hover over the path. A preview line should appear.
click and start drawing.
The end of the path will be removed and replaced with the one you draw in step 3.
