For now, the link works for a wide variety of connections/joints. However, please take into account the unsupported functionality.
Limitation: Moving (stepped) Load Case is not imported to Checkbot. Load combinations containing a Moving (stepped) Load Case are imported, but Moving (stepped) Load Cases and their internal forces are not included.
Workaround: Explode the Moving (stepped) Load Case into single load cases in Robot Structural Analysis using the "Create a case from component" command. Then, import the connection or member, and these load cases will be imported separately as well as included in the defined load combinations.
