I can use the tool box objects but only in the standard given dimension . i am not being able to change its dimension when i am trying to create a new part out of it.
Changing dimensions outside of their pre-configured sizes isn't really the intention. If you are taking a tool box part and want to use it as a regular part you need to remove the tool-box flag.
