### 13.4.1 Define a point in three-dimensions: point

See section 12.6.2 for points in the plane.

With the 3-d geometry screen in point mode, a click on a point with the left mouse button will choose that point. Points chosen this way are automatically named, first with A, then B, etc.

Alternatively, the point command chooses a point, where the point (a,b,c) is specified by either the three coordinates a,b,c or a list [a,b,c] of the coordinates. Many commands which takes points as arguments can either take them as point(a,b,c) or the list of coordinates [a,b,c].
Input:

point(1,2,5)

or:

point([1,2,5])

Output:

(The marker used to indicate the point can be changed; see section 12.3.2.)
