i have na assembly whith 2 parts that are the same but i need to have a small change between them so is it possible to have diferente configuration of the same part at the same time in na assembly?
Yes, as long as you have more than one instance of a part in the assembly.
Select one of the parts in the icons that pop up, select the configuration from the drop down list.
You can also right-click the part in the tree.
