Hello,
I would like to see the " Instance Length Parameter with Grips" for the given family in the project file.
The minimum overall height of the family is 10' and Max 14'. It should vary from 10'-14'. I will adjust it based on my requirement in project file.
Make sure the given Family is already controlled by angle parameter.
If it is not controlled by angle parameter then it works to give instant length parameter with grips.
Here I am attaching the file for your quick reference.
Thank you
