The Pipes Category does not appear to be available for use in Material Takeoff Schedules. You may be able to rig something up with a normal Pipe Schedule using Sort/Grouping and Calculated Values. If you need more assistance, can you provide more info on what information you need?
Thanks for the info,
i was able to kind of get a solution with using the comment ans the filters commands. The other problem im having is when im selecting a underground sanitary waste pipe it only selects the lateral line but for an accurate takeoff i need to get the risers as well. any tips thanks
