how do you place such parts (eva repair kits) on vessels?

[tonimark]

these parts were suppose to be in the cargo payload but how did this guy managed to attach them into a vessel? i am talking about eva seal pod craft from steam... but anyways heres is the screenshot:

part-clipping and non-strict part attachements checks don't really do anything while turned on/off in the editor

do i need a specific mod or a technique instead?

I was wondering about this as well!

Parts such as the EVA Repair Kit are cargo/inventory parts.  They can be carried in inventory slots that exist on each Kerbal, in each command pod, and in special cargo carrying parts such as the SEQ-3 Cargo Storage Unit.

When you pick up the EVA Repair Kit in the VAB, those parts already on the craft which have inventory slots will show up as blue.  If you move the mouse over one of the blue parts, the part action window will open.  You can then drop the EVA Repair Kit into any empty slot.

Please note that each Kerbal already has both slots filled by default, one with an EVA jetpack and one with a parachute.  These can be removed during vehicle assembly.  Also note that all cargo/inventory containers (including Kerbals) have mass and volume limits.

There is much more to this topic but, hopefully, that is enough to get you started.

Happy landings!
