[SOLVED] Using a building block for macro generation or how to get own block

I changed the building block "Transform to Nominal" to something different because
I dont know how to establish my own one. Inside this building block ("GetReach") I
define some macros but these macros are not visible to the main process ("%{last}").
Whats going from ? -Frank

    Hi Frank,

    the Transform to.. operator is executed after the other tree operators. Please click the button with the blue arrows and the question mark on top of the process pane to fix the execution order. To bring an operator to front in the execution chain, right click on it and then select "bring to front".

    To create custom building blocks, select the operators that you want to save as building block. Then go to Edit->Save as Building Block.

    Ah, execution order...I never saw it before. Thx.
