Basic drawings

This section is devoted to a loose category of drawing: those that use the fundamental facilities of Adage. Some features of these include:

• The drawings are moderately simple compositions of lines, points and text, and of simple filled areas. Lines are either straight or basic curves, such as circle arcs.
• Straightforward geometric construction is used. Examples are points of intersection of two lines, mid-points of lines, and perpendiculars.
• Angle-preserving transformations (scale, rotate, and translate) are employed.
• Reasonable sophistication is required in text placement. In particular, text can be placed with good controlled spacing next to a line or in a corner.
