- =========
-
- v2.32 13/8/2000
-
- This little application sits on the icon bar, and
- produces Draw files of various geometric shapes.
- Clicking on the icon-bar menu opens a window in
- which the various choices are made.
-
- The window has four sections, described below.
-
- Groups
- =======
- In the top section, one of 4 sets of shapes may be selected.
- The shapes in the selected set are displayed in the second area:
-
- Shapes
- ======
- Curved Arc
- Sector
- Segment
- Ring segment - setting angle to 360 gives ring
- Curved Polygon (50p piece)
- Cog with square teeth
- NB a cog with pointed teeth can be made from the Star
- shape in the Other section.
- Spiral - of the form radius = constant*(angle ^ power)
- NB These become VERY large if power>2 and Turns>2.
- power=1 gives the Archimedes (equiangular) spiral.
- SineWave
- Flower - with smooth petals
- Flower2 - with double petals
-
- 4-sided Curved Box - a box with curved corners!
- Cut Box - a box with cut-out curved corners!

- Drawfile style
- ==============
- in the third box, one of four line widths may be selected.
- The dimensions can be specified in inches or cm.
- If Fill is selected, a choice of winding rules may be made:
- check on LineStar to see the difference.
-
- Parameters
- ==========
- The final box changes depending on the choice of shape, and allows
- the necessary values for each shape to be entered in 2 or 3 writeable icons
- eg number of sides and their length for a polygon,
- width, height and radius of curve for a cut or curved box.
-
- By default the shapes are all saved as black lines, filled in white if Fill
- is selected, but the colours can easily be changed by changing
- the system variables DrawLots$Fill & DrawLots$Line, in the !Run file or
- at the command line. They should be set to &bbggrr00.
-
- Incidentally, an effective frame can be made from a series
- of cut boxes of increasing line width and size.
-
- Preview
- =======
- Clicking the Preview button opens a window which displays the
- currently set shape. The shape is automatically redrawn after
- changing any settings. The preview window has a coloured background
- to show up any filled shapes. For the 3 and 4 sided shapes, a window
- will open given details of the sides and anlges of the shape.
-
- Saving
- ======
- The shape can be saved, or dragged directly into !Draw, by
- pressing Menu over the window, which gives a save box, Clicking on
- the Save icon or from the icon-bar menu.
-
-
- Defaults file
- ============
- The default shape, line width and units and default values for all the
- shapes can be changed by editing the file !DrawLots.Defaults - the
- format is fairly clear!
- The order of the shapes in each section can also be changed by changing
- the order of the lines in this file - but KEEP A BACKUP before modifying
- it, and do not change the numbers at the start of each line, or the
- program will fail to work correctly.
-
- For use with younger children, the lines corresponding to any unwanted
- shapes can be commented out by preceding them with | - they will then
- not appear on the display. Any group with no shapes will not appear
- in the list.
-
- The icon-bar menu gives access to the Details file for editing, but the
- new values will not take effect untl the program is re-rerun.
