Attempting to add Transformations to IF/THEN statement

[Patrick May]

Sorry for the simplicity of this question; I should know how to do this, but I can’t figure it out. I am building an appliance and want a control to open the lid. I am trying to add a series of transformations into the script but keep coming up with an error. My script as typed is:
IF HoodPosition = “Open” THEN
ROTx 294
ADDz 0′-10 3/4″
ADDy -3′-6 5/32″ ELSE
ENDIF
!script here
DEL TOP

This is giving an error message as soon as I include the ADDy & z commands. Thoughts on what is wrong?

I have never used Imperial measurements in a script but I suspect what you have shown is incorrect.
ADD command requires just one value, you seem to have two for each.
There must be another way of writing it as one figure.

ELSE must be put into a new line!

@joachim, that was it. I eventually tracked that down. Apparently I don’t even need the Else line for this stack to work, I just had it in there by habit.
@barry, imperial feet and inches do work, as long as they are consistent. they can be foot + inch or decimal feet.
Another odd thing about this script is the DEL command. for some reason DEL TOP works, but DEL 3 doesn’t. DEL TOP got the job done, but I’m not sure why I couldn’t be more selective.

Joachim is quite right.
Another nice way to keep track of your transformation stack is to assign a variable to count every trafo you make:

_nTrans = 0
IF HoodPosition = “Open” THEN
  ROTx 294
  ADDz 0′-10 3/4″
  ADDy -3′-6 5/32″ 
  _nTrans = _nTrans + 3
ELSE
  ! whatever, just keep track of transformations here as well, if you use any
ENDIF
!script here
DEL _nTrans

This way you don’t have to use the condition again to enable the DEL command.

DEL 3 works only as follows:

IF HoodPosition = “Open” THEN
ROTx 294
ADDz 0′-10 3/4″
ADDy -3′-6 5/32″ 
ELSE
ENDIF
!script here
IF HoodPosition = “Open” THEN DEL 3

Otherwise you will get an error if the condition is not true.
