hi~~

here is the beginner trying to use revit and facing some big issue 

so i have made a model with several windows on it, and when i edit the height and the width on window A and the other window B and C  change too. then when i  went to edit window B and window A and C change too. 

i want all of them to be in different dimension, how can i fix this problem 

and i have never group my window together, i have no idea what is going on and what should i do to fix this problem. 

will prevaricate people who could help me fix this problem

your windows are constrained by a type parameter (dimension)

windows A,B,& C will always be the same dimensions because they have been built that way.

select a window and go into the EDIT TYPE button on the Properties panel 

Duplicate the Type in the top and Rename it to another type I named my examples as A,B, & C

(see image below)

Because they are of the same type.  Two ways:

- Select the window you want to change, edit Type, duplicate, and change the dimension

- If you have a lot of different heights and you want to just select a window and change it then Edit the family, go to an elevation, select the height dimension and tick Instance from the option bar on the ribbon.

Make sure all the windows are different types....  How are you changing the sizes by the way?  Are you editing the family directly?

The question will be on the test.
