I took my first course on how to be a sketch artist this week. I am already drawing large crowds.

Loci is drawing out something that satisfies certain conditions.

Locus is a path formed by a point which moves according to a certain rule. The plural is loci.

Lets have a look.

Example 1

Open your compass to 2 cm and draw around the point stated. All points are the same distance (equidistant )from the centre.

Example 2

Measure 5 cm away from the wall and draw a horizontal line. Each point on that line will be 5 cm away.

Example 3

To get the curved edges open your compass to 5 cm and draw an arc from each end of the line.

Example 4
