Drawing Tab Controls |

From left to right:

- Curvature - lines, and the lines in squares, rectangles, and polygons, can be curved.

For geometric shapes positive values cause the lines to curve outward and negative values cause the lines to curve inward.

For lines positive values cause the line to curve counter-clockwise to the origin. ie a line drawn left to right will curve upward.

The dropdown box selects which way the curvature is expressed:- Radius - the curvature is given as a radius in virtual units and must be at least half the length of the line.
- Abs curvature - the curvature is given as the deviation from a stright line at the center in virtual units. If the shape is resized in any way the curved lines will not change curvature and the resulting figure will be altered in appearance.
- Degrees - the curvature is specified in degrees in steps of one tenth of a degree.
- Rel curvature - the curvature is given as a value relative to the length of the line with 4320 being the full length. If the shape is resized in any way the curved lines will change curvature to maintain the same figure.

- Add Brush - polygons with more than one interior region can use multiple brushes to add more colors.
- Edit Brush Color - allows changing the color of a brush.
