Importing knx project file after modifications

[Daniel]

Hi
It depend. Each group has its parameters and if you delete group the parameters are also deleted. When you import new objects then they may not have correct DPT like 1byte unsigned instead of scale. All depend of what changes you did to the objects after importing original.
In Short all object parameters will have to be re-done so it is better to delete only the ones which were changed.
