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 'tick' 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.
