Flexible heads are still relatively new and few people know how to use them in a drawing, so here goes:
Please note that we only have the brand name Flexhead in our database at this point.
1. Put some symbol representing a sprinkler head in the location where the sprinkler head is actually going to go. You can explode one of our heads or make your own. Put it in some benign layer like DMNS, TEXT or your own.
2. Connect these fake heads back to the branch line using a line or pline in the same benign layer.
3. Define a ‘real’ head as an On a Sprig and choose the proper Flexhead type from the Material pulldown
4. Insert these real heads at the point where the branch lines meet your fake lines going to your fake heads
5. Shrink the real heads down so they cannot be seen – we usually use 1/20th (.05)
When you calculate the job you will have to add the Flexheads in as a fitting. If you do not see these as an option, you will have to download the flexheads from the Update site under Data / HydraCALC. You will need to give them a short name in HydraCALC / Utilities / Alter Pipe and Fittings.
HydraLIST will work just fine as is
