AllyCAD TECH TIP


Making Calculations

This Tech Tip explains how to use AllyCAD's built in calculation facility.

Whenever the CAD prompts you to enter a distance, be it diameter, radius, length etc. you can enter that distance as an arithmetic expression, e.g. 120/2.



This expression is calculated when you click on the button, or press [Enter] or your right mouse button after typing the expression, resulting in the correct distance being used.

 

You can use the following functions:

* multiply (use the * on the numeric keypad).
 
/
 
divide (use the / on the numeric keypad).
 
-
 
minus (use the - on the numeric keypad).
 
+
 
plus (use the + on the numeric keypad).
 
^
 
power, e.g. 10^2 (ten to the power of two).
 
sqrt(x)
 
square root, e.g. sqrt(100) (square root of 100).
 

The functions sin(x), cos(x), tan(x), asin(x), acos(x), atan(x), atan2(y:x), int(x), abs(x), log(x) and ln(x) are also available.



Standard mathematical hierarchy applies, and brackets can be used to force the sequence of operations. The correct use of brackets when using + and - in combination with * and / is essential.
