YAY! Happy to be judged on *words* and *actions*. Also loving how active this thread has become!

Now back to the party with another **AX video tutorial**! The BIGGEST one yet!

**ARCHIMATIX: EXPRESSIONS and MATH FUNCTIONS**

Learn how to write:

**Relation Expressions**ā modify node-to-node parameter connections**Parameter Expressions**ā modify a node with complex math functions and custom parameters**Logic Expressions**ā embed functions within the Turtle script- Functions discussed:
**Ratios**,**Greater**,**Lesser**,**Range**,**Sign**,**Sqrt**,**Atan2**ā¦ - Create a
**Math Function Node**that calculates*Hypotenuse*and the angle*Theta* - BONUS: an introduction to
**Turtle Script**in Archimatix (spoiler: itās not hard) - BONUS: add
**Conditional Logic**and bool switches to enable and disable logic functions

I use TTS voices because they speak twice as fast as I do (and the extra effort of getting them to pronounce āarchimatixā lol), which allows me to pack a 30min tutorial into a 16min video. As always, I try to show EVERYTHING step-by-step and explain each concept for beginners and pros alike, but it goes fast and the voices arenāt perfectā¦.

This video is longer than the others because EXPRESSIONS are the ābrainsā of parametric and runtime models. As @syscrusher said, the real learning begins when you dive in and try it for yourself
