In the list of project items under Connections and with a connection highlighted in Checkbot you can either right-mouse click and select Open or click the ribbon command Open to start designing, code-checking, and reporting.
The settings of members are taken from the original BIM application. You can, however, change the section size of any member on the main Checkbot screen but this will break the link with the BIM application in this session unless it's synchronized again.
The imported connection is opened in the IDEA StatiCa Connection application.
