definition of pipe | and single quote '

[DrMichaelMartin]

Hi All, I was wondering if anyone might be able to help understand a pretty basic operator question about CGA.

I've searched the documentation but I don't seem to be able to find a place in the CGA docs for what the pipe character: | and the single quote: ' do? I can see how they are being used but a specific definition eludes me.

Thanks!

Hi @DrMichaelMartin,

Pipe is used to define multiple component or subdivision splits. Single quote is the relative operator for values to make them relative to the the current scope (See Coordinate Systems).

I suggest to read through the Essential Shape Operations section in the help, especially:

• component split
• subdivision split

There are also many explanations and examples in the cga refererence for those operations:

• comp operation
• split operation

Hope this helps,

Best

Thanks Jonas, That does help! Still getting my head around the CGA paradigm after living in OOP for a long time. 

Best,

I see where you are coming from. What helped me personally to advance is reading through the CGA modeling section in the help (where I put some links in the previous post) and look at existing rules in examples/tutorials/ESRI.lib with the Model Hierarchy and most importantly start to write some actual rules by myself.
