Hidden parameter

[Bruce]

I am writing a simple (ish) library part that I am using in an element schedule.

It is a rectangular panel that can be open to 0°, 45° or 90°. When open to 45 or 90, the panel is lined front and back. When it is at 0, it is only lined on one side.

I have created a parameter called lined_back (Lined both sides) as a boolean, which is meant to turn on or off depending on the opening angle chosen.

Two problems:
1. As a boolean, when I try to change the value in either the Master Script, Parameter Script or 3D script, I get a "unititialized variable" error (strangely enough, only in the ELSE portion of my IF statement). I can get around this by defining it as text, and changing from "yes" to "no". Clumsy, but it works - I would rather use a boolean.

2. I don't want the user to change this value, so I have hidden it. Problem is, if it's hidden, you can't list it in a schedule.

Ideas anyone?

To add to the previous post: I can use the LOCK command to grey it out...but I still can't change the value of the parameter by code (can't figure out why).

I've tried it in the Master, Parameter, Interface & 3D scripts - no luck. And if I can't change the parameter value, it won't change in the schedule.

Have you changed the value and THEN set the Parameter Value?

lined_back = 0

PARAMETERS lined_back=lined_back

If you just set the PARAMETERS value, The parameter value changes, but it doesn't change the value for the rest of the scripts. It would take another run through all the scripts for the vaule to change.

Champion - that's it!

Hello,

If you hide the parameter with command
hideparameter it is available in the
schedule and not visible to the user.
(So do not use the hiding check box).

Hope this helps.

Point 2:
I don't know If it works, but try r´this:

IF GLOB_CONTEXT # 6 THEN HIDEPARAMETER "lined_back"

6 is the context of list generation.

Hello,

I think it is not mandatory - hideparameter
does not hide parameters in schedules,
only the hiding check box does.

More excellent tips - thank you very much!
