CoPlot's versatile drawing objects make it easy to create precise technical drawings. Although there are just a few types of drawing objects, each object has a large number of attributes which you can edit. The result is that each type of drawing object can be used in many different ways.
To use CoPlot, you:
The types of drawing objects are:
The drawing below illustrates some uses of Path objects. By setting the 'Path Type' attribute to 'Spline', it is easy to make nicely curved lines. The 'Background Color' attribute allows you to color the interior of the wing's outline. Path objects can also be used to draw straight lines and dashed lines (also in the drawing below).
Image objects can also display icons (32x32 pixel images). CoPlot comes with thousands of icons arranged in 70 icon groups (animals, plants, people, computers, etc.). Icons look great on screen, but don't look as good when printed. They are very useful for creating diagrams which will be viewed on screen.
Text and Big Text objects in CoPlot can be drawn within a shape. There are about 40 shapes to choose from. This makes it easy to draw block diagrams, flow charts, UML diagrams, organization charts, etc.
Tags For Formatting Text - Text in CoPlot can include HTML-like tags to control subscripts, superscripts, italics, underlining, bold, etc. For example, '<b>' makes subsequent text bold. CoPlot supports some non-standard tags to help you format mathematical equations. Wherever tags can be used in CoPlot, there is an '&' button which pops up a list from which you can pick a tag. Here are examples of most of the tags:
Greek and Other Special Characters - Text in CoPlot can include Greek and other characters which are picked from lists of HTML-like character entities (ASCII names for characters, for example, 'Á' generates 'Á' and 'μ' generates 'µ') which are arranged in groups. Wherever character entities can be used in CoPlot, there is a '<>' button which pops up a list from which you can pick a character. Here are samples from most of the character groups:
Here is the list of characters in the Math group:
There is no special "arc dimension" object. But since ellipse objects can
be made into arcs with arrowheads at both ends and with text labels, they can
be used to label arc dimensions. In the text for the ellipse's label, you can
embed a special text tag
("<arcdimension>") to display the current arc dimension.
Graph objects are discussed in detail here.
If you use "Create : Pie Chart" a few times and edit the attributes of the resulting ellipses (notably, their Size and Inner Size), you can make a multi-pie chart:

The features of CoPlot described above (different types of drawing objects, text tags, and special characters) combine to make it easy to make a broad range of technical drawings. Here are some examples.
Electrical Schematics - Because electrical symbols are in one of the groups of special characters, it easy to draw electrical schematics. Here are the electrical symbols and a simple schematic drawing:
Chemical Structures - CoPlot isn't specifically designed for drawing chemical structures, but it has some features which make it pretty easy to do. One of the lessons in the program describes how to do it.
Landscape Designs - CoPlot has a font with landscape symbols, which simplifies the process of making landscape designs and field maps.
Field Maps and Groups - In CoPlot, you can assign drawing objects to different groups and you can control whether different groups are visible or not. Thus you can make field maps where the map is in a background group and the crop history for each year is stored in a different foreground group (which you can make visible or not).
Here are some other drawings made with CoPlot.
