From a customer: Is there a way to edit the length of multiple riser nipples at once?
Answer: If they are a Specified Length, then yes. Type in CL to launch the Change Length command. Check the Filter a Specific Block to do many RNs at one time
If they are Computer Generated, then just adjust the pipe elevation markers to the proper value. Once the building is elevated, the riser nipple lengths will recalculate.
