# Single Node Names

A node is a point in 3D space. Nodes can be constructed and referenced using variable names. Use a loop to construct multiple nodes.

When defining or using node names, simple variable names of the form A#i can be used to define the node. If a hash character (#) is found in a node point name, this character and everything that follows is interpreted as a variable string, evaluated and rounded to the nearest integer.

As an example, #k=15 and a point defined as P#k, is equivalent to using P15 as point name. The length of the node name string (before and after expansion) is limited to 5 characters.

For example, the points P1 to P20 are defined inside a loop as follows:
!!for #k = 1 to 20
DP P#k
!!next

These defined points can then be used individually or inside another loop.
