   It can only be used to draw a line segment between two points, or to extend an existing line segment. The compass can have an arbitrarily large radius with no markings on it (unlike certain real-world compasses). Circles and circular arcs can be drawn starting from two given points: the centre and a point on the circle. The compass may or may ...

A drawing board was used to hold the drawing media in place; later boards included drafting machines that sped the layout of straight lines and angles. Tools such as templates and lettering guides assisted in the drawing of repetitive elements such as circles, ellipses, schematic symbols and text.

7. Compass equivalence theorem - Wikipedia

   en.wikipedia.org/wiki/Compass_equivalence_theorem

   Given points A, B, and C, construct a circle centered at A with the radius BC, using only a collapsing compass and no straightedge. Draw a circle centered at A and passing through B and vice versa (the blue circles). They will intersect at points D and D'. Draw circles through C with centers at D and D' (the red circles).
