This Tech Tip explains how to use Civil Designer's built in
calculation facility.
Whenever the program 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.
