Does anybody know if Hexagon offers a (more or less) programming class to learn to use expressions? I've been wanting to get started on these, and reading through the core files. I can think of several ways at least that they can be used here. Locally there is a metrology shop that offers a four hour course, but I took Java in college and as I recall programming isn't something you pick up in four hours.
The topic is hinted at in the level 2 training, and covered somewhat in level 3. I learned mostly from the help files and the forums, so the level 3 class was almost a review for me.
I reckon as long as there's so much good help to be found here I'll just go with saving the money. This forum has been very helpful. Sometimes I just read the strings to gather as much info, tips and tricks as I can.
Anywhere you have a number that can be edited in the Editwindow, you can insert an expression instead (there are probably some exceptions, intended or unintended...)
Expressions can contain variables which get their value from ASSIGN commands
Pressing F9 on an ASSIGN command, and then clicking From... opens up the expression editor, which is a great help in finding out what functions exist, what values can be fetched from features, dimensions, alignments etc.
Pressing F1 (Help) in the expression editor gives more info

It's a good way of learning as the drop lists are dynamic - i.e. if you select features, the next list is populated with a list of features to pick from, pick one of them and the next list is populated with a list of properties to pick from.

Even easier: highlight the field you wish to edit and hit F2 to open the Expression Builder directly.
My "mentor" will be here this week to do some setup on PCDMIS, and while he's here we will be discussing this, along with where I can make use of it. I sure appreciate the help from all y'all.
