Update parameters in placed objects?

I have a faint memory there is a command to "force" run parameter changes in gdl objects. I'm playing with locking parameters and if I change to lock between A and B dimensions it doesn't stick on alreday placed objects. Why so?

So, you have scripted something like LOCK "A" in the parameter or master script of an object and saved it (not 'save as').

All existing instances of that object should now have parameter A locked (greyed out in interface).

Is that what you mean?

 

You have labelled your post "Library Part Maker".

Is it in particular to do with that or did you just pick a label?

If you have a variable in placed objects, which you would like to update to a new value, i do suggest renaming that variable in your parameters as well as in all other scripts.

AFAIK already placed objects will remember their own placed value for exampleVariable = 0.5 but will update to your new value if renamed exampleVariableNew = 0.7.

 

Or - depending on the situation - you might force your variable to take a new value within your Masterscript: exampleVariable = 0.7. But this might prove to be a too static solution

Yes about Lock "A" in the parameter scripts and then save.

See super short clip.https://youtu.be/DBSzrU-KC9E 

Library Part Maker tag was because GDL tag didn't show up...☹️

 

It is a bit sticky.

I just tried it myself.

 

I thought it might be better if LOCK was in the master script, but it doesn't seem to matter.

 

When you change the LOCK fro A to B, the object is frozen, but only on the first try to stretch it.

Try to stretch it again and it will work.

Or open the object settings, and just OK and it will stretch.

 

There is a command you can add into your Work Environment (menus or toolbars or keyboard shortcuts).

But it seems to take quite a long time to run, and that was in an almost empty template with just a few dozen objects placed.

That's the one I was looking for. Thank Barry!
