Imported Objects cant be exploded or manipulated

Hi all

I have imported a couple of small objects from free libraries into a drawing,

one of these is a robot figure, one is an outboard motor

Neither can be manipulated after the are Exploded, and the entire objects are selected when any part of them is selected,

how is this done, and how can they be unlocked for manipulation ?

Try to explode/ ungroup a couple of times.
Else maybe a file so we can check?

3

Try ExplodeBlock on these.

Thanks guys. The UNGROUP command worked, where Explode didnt.

I will have to research those options

Many thanks again
