Onshape + Operators (Free Tutorial!)

Did you know you can use operators directly within a part studio?

Here's a re-post of some useful info I put together a while back.
Looks like the tables aren't supported in the forum update. Original post is (here) in case your eyes hurt from these tables.

Also, if you would rather watch a video tutorial on operators see: Lesson 2 starting at time 11:54

Ternary conditional operators are extremely helpful for creating variable patterns and models. They are a short hand version of the "if then statement" that you can use directly in the Onshape input boxes within features or variables. Here is a quick guide on how to use them:

In this tutorial gif, you can see how to change the quantity of a pattern based on the diameter variable. If the diameter is less than 2in, use qty of 6. If the diameter is not less than 2in, use qty of 4.

Ternary Conditional Operator Examples

Return one value or different value depending on if the statement is true or false.
logical statement ? value returned if statement is true : value returned if statement is false
1 == 1 ? 999 : 555	this returns the value 999 because 1 does equal 1
1 == 2 ? 999 : 555	this returns the value 555 because 1 does not equal 2
1 != 1 ? 999 : 555	this returns the value 555 because 1 does equal 1
1 != 2 ? 999 : 555	this returns the value 999 because 1 does not equal 2
1 < 1 ? 999 : 555	this returns the value 555 because 1 is not less than 1
1 < 2 ? 999 : 555	this returns the value 999 because 1 is less than 2
1 <= 1 ? 999 : 555	this returns the value 999 because 1 is less than or equal to 1
1 <= 2 ? 999 : 555	this returns the value 999 because 1 is less than or equal to 2
1 <= 0 ? 999 : 555	this returns the value 555 because 1 is not less than or equal to 0

Combined Logical Statement Examples

Use modifiers to combine multiple statements
(1 == 1) && (2 == 2)	This statement returns true only if both statements are true
(1 == 1) || (2 == 2)	This statement returns true if either of the statements is true

.

Nested Ternary Conditional Operator Examples

Place statements within parenthesis to nest them
1 == 1 ? 999 : (1 == 2 ? 444: 333)	Returns 999
1 == 5 ? 999 : (1 == 2 ? 444: 333)	Returns 333
1 == 5 ? 999 : (1 == 1 ? 444: 333)	Returns 444
