PSDS to OpenPlant V8i migration and HVAC components

Hi everyone,

we're migrating some dgn files from PSDS to OpenPlant V8i application. For piping components the procedure create weld joints and the pipe line is entirely connected. This is not true for HVAC components that are all not connected. My question is, is there any problem in the components itself or the migration procedure does not create joints for HVAC ?

 Thanks all for answers. Regards,

Simone
