export for existing items

オフライン

hello, 

i have been diving into packaging and exports lately but there is something i can't figure out. it might seem easy but it's not said clearly anywhere i looked. 

So, let say i customize an already existing item like Parts,  i had actions, modify the forms and i want to export my work

the next step i need to follow are:

1)since itemType Part is in package "com.aras.innovator.solution.PLM" i had to this package the actions, methods, forms and all items that i could have added to the part item types.

2)then using the aras export tool i can either export the whole package or only  the things i just added to the package.

please tell me if i'm right wrong or if i'm lacking some part.

thanks,

lucas
