HOW TO MATCH BOP ELEVATION

try the following

1. click on the elbow

2. enter "BOP TO LBOP OF ID@" then click on the Pipe 

DEAR CRAY,

PLEASE CHECK THE BELOW SNAP 



KINDLY LET ME KNOW IF ANY COMMAND

REGARDS & THANKS

Sorry, my sample was both elbow wan in the BOTTOM SIDE, in your case you may use the following;

BOP FROM LBOP of ID@ (full command is BOP 0 FROM LBOP OF ID@ as you can indicate the offset of BOP from reference)

you may also use BOP ONTO LBOP OF ID@ as this will not matter the flow

and if the FLOW of the large pipe is DOWNWARDS

you can use BOP ONTO ABOP OF ID@

ABOP - BOP Position of the Arrive PIPE

LBOP - BOP Position of the Leave PIPE

Dear CARY,

Now it's working 
Thank you sir

Thanks & Regards,

THIRA

You could also consider using DRAG command together with Cary's syntax.

For example:  DRAG BOP ONTO LBOP OF ID@

This will move a complete branch leg and not one component only.

Thank you sir
