Hi everyone,
I’m having an issue in the following script.
In an earlier version of this script, an pre-drawn object (“Pyramid01” ) is copied and aligned to one of its 12 faces. The face is referenced using a variable “n” and a number between 1 and 12 (changing the n variable value from 1-12 changes the location of the new object). This worked fine.
However, I wanted to designate the face using letters instead of numbers, so I added the “case of” statement. When the script runs, some letters (like “d” for instance) don’t return the right value and the newly placed shape ends up in the wrong place. Other times, the letters don’t seem to affect the outcome at all and the shape keeps getting placed at the same location (is this a scope issue?). I probably have incorrect syntax for the “case of” expression too, but I’ve looked at the help and online and this is the best I’ve come up with (and like I said, it has worked intermittently in the past).
I’m including both the script that works with numbers, the script I’m having issues with and the file that goes with either script, if anyone has the time/inclination to help. I’m still a noob when it comes to programming, so any suggestions are welcome.
TIA!
