connections problem
 

i have a probleme with connections -any type of connection-, the selection on the model works , but it is not taken into the details of the contact tool (always the case is yellow , and it appears "no selection").

before it was workin correctly , but i modified my geometry (import new modified one from cad geometry (SAT file),some old connections work but i can't be modified ,some are no more valid and wthever i select bodies yelow color persists (no selection made appears).

i cheked all the options (import option etc...) but nothing changes

please i need your help
thank you.

you should reset that what you made.
