Only the options DOT and INSERT let you select an icon and place it onto a single position of the board.
DOT option has overwrite mode: the icon will replace an existing piece of graph.
In all other modes (except DECO LINE) the system will (try to) add lines and curves without deleting existing ones.
INSERT mode is like DOT, but :
- you have to select one of the eight most simple pieces (horizontal line, vertical line, diagonals, and 4 simple curves, marked green) to inserta line piece without overwriting.
- if any other graph piece is selected, you can only draw to an empty position.

DELETE mode: click a position to delete its content.
RED mode: click a board position to toggle between red and black colour.

The SQUARE/RECTANGLE/BOX drawing modes do not use the selected image from the selection menu, but rather draw the outlines of a square/rectangle/rectangle-with-rounded-corners.
The BOX mode draws a rectangle with ROUND CORNERS if the chosen width or length is greater than 1 unit.
Always mark the top left corner first, then the lower right corner!

The SQUARE/RECTANGLE/BOX/LINE/DOTTEDLINE/POLYLINE drawing modes do not overwrite the existing drawing, but rather add lines, just as one would expect from a line drawing program.
If possible, avoid crossing two curves on one position because only a few such cases are implemented (note that there are only a few icons for this in the selection menu, marked yellow).
Apart from this, all possible line/line, curve/curve and curve/line combinations are implemented.

In the drawing modes SQUARE/RECTANGLE/BOX/LINE/DOTTEDLINE/POLYLINE the chosen from-position, if not-empty, is highlighted in red colour.

When using POLYLINE, remember that you have to finish the polyline before you can select another mode.
To finish a polyline, you either:
- click the red end piece of your polyline This will paint the last missing segment in most cases, therefor strongly recommended.
- or click the POLYLINE button, which simply paints the red to-position black, but which may leave the last graph piece undrawn.
The POLYLINE concept has not been fully developed in this game, which the result that some automatically created corner pieces are placed in overwrite mode.

DECO-LINE fills a line with the selected icon.

Hint : Hit F7 regularly, e.g., to see where you can place the lower right corner of a square.
Please note that there are eight pieceset/board combinations available!

 
'Linedraw' has been developed from the (now redundant) variant 2 of the Zillions game 'Draw'. Because of its greatly increased amount of code, versatility and imagery, as well of its changed focus, Linedraw is now a game on its own. It also has an increased board space of 30x30 position, and loads much faster.

Linedraw has quite a bit of 'intelligence' built in to make it work as expected, (when it tries not to overwrite existing graph, and for the polyline).
