impossibility to take odds (external references) with "conserve the connection with the selected object" active

[Nigredo]

Good morning to all,

I am having the following problem on catia:

are currently inside a catproduct containing two catparts.

I activated in the options - under part infrastructure - the check "keeps the connection with the selected object".

I have successfully created links between one catpart and the geometries of the other (works correctly and update according to external references as duty); However if I try to create a sketch within the second catpart does not allow me to project* or to select geometries of the other unless disable the check "conserve the connection with the selected object"; can therefore quota only on internal geometries to the same.

*in case you try to make projections the message "projection on the plan of the unsuccessful sketch: it is not possible to project the selected elements".

Is there a way to solve this problem or the limit of this function in the fact that it cannot create links from both sides? (reforming the question, is it normal that once you create references to a catpart I am unable to make the opposite and create references to the first catpart? )

Thank you in advance.

rectifying: when external references are imported within a catpart the latter is as non-existent (not selectable) when working on catparts from which references have been taken.

you will not be able to select faces or edges, or project any geometry as they are blocked, at least until you disable the function "conserve the connection with the selected object".

It's not possible. . because it's round.
or the catpart "a" commands the catpart "b"
if you make a change on the catpart "a" automatically updates the catpart "b" and then the system goes in tilt.

you have to do a master catpart and generate two links for a catpart "a" and a catpart "b"
after that.. you can copy geometries from the master catpart

try and let me know

Thank you very much,

I don't just understand what you mean to "generate two links."
I tried with the special paste function that however does not allow me to copy with connection, but I can repeat the instance as specified in the structure (which does not solve the problem anyway).

the link is equivalent to "copy with connection"

I thank you again for the promptness, unfortunately being only a repetition in this way you can not solve as it remains blocked as the "father".
