Did you know that AutoCAD’s CAL command has a memory? It does.

If you are not familiar with the CAL command, learn more…

Type CAL (or ‘CAL for transparent use) on the command line. At the Expression prompt type [anything]=[expression]. [anything] is the stored variable and [expression] is the actual expression. For example, if I wanted to save the calculation 1000 multiplied by 9 into the memory as “A1″, I would type:

A1=1000*9

In this case “A1″ is saved into the memory as “9000″. If I wanted to call it up in another expression, I could use it in place of a number. For example, if I typed CAL on the command line, and at the Expression prompt entered:

A1/2

It would return the answer as 4500.

After Labor Day I will talk about using Pi in calculations. Have a wonderful weekend!
