thank you for the eplanation but it didnt anser my question.
i might just be saying it wrong.
so here is a second try.
in i logic if you change a parameter (example:from 100 to 260) in in the form section, it will automaticaly update from 100 to 260. i would like to change that. i would like to change more parameters in one go and update them at the same time.
Id like the activation to be a button.
i hope this helps
Hi @Anonymous
I think tobias.wiesendanger answered your question then, if you set the form to use the OK Cancel Apply then you can choose when to update the model after the parameters have been changed in the form
Here I have a form with two model parameters named Count1 and Count2

When I open the the form the buttons are grayed out:

When I change Count1 and then click on Count2 (or use the tab key) the buttons become active, but the model does not update
At this point I can choose to click Apply to update the model or I can choose not to click any buttons...
..
If I choose not to click any buttons, I can change Count2, and then when I click either the Apply or OK buttons both parameters will be updated and the model will change.

If this still doesn't answer your questions, then providing an example file or example code to help understand your issue is likely the next step.
I hope this helps.
Best of luck to you in all of your Inventor pursuits,
