is there a way to add dripline header as a pipe? we have to manually go back and add a thick symbol at the ends or middle of our drip line areas to help show the contractor how we want to connect the lateral pipe to the dripline area. I would like to be able to draw a thick or dashed line that represent these headers in the legend and maybe calculate the combined length.

thanks.

Bob,

Currently there is not a way to add headers and footers to your drip zones. The way you are currently doing it is the only way as of now, however, we do already have it on the wishlist to allow the user to specify the header, footer, and size. If you are looking to get an overall Linear Foot total, you could keep your headers and footers on designated layers and use our Length RefNote items to then assign to each respective layer. Running a RefNote schedule will then list the totals for anything on your Header/Footer layers.

Here is a link that shows how to use this tool:

Bob,

I don't know if this help here's how we do it:
- Separate our dripline areas into serviceable areas with a maximum flow that a 3/4" PVC header can accommodate.
- Use varied angles of the hatch to define the different areas which are adjacent to each other. We change the hatch angle by clicking on a line going a different direction prior to identifying the area with the hatch.
- Then we identify the supply header by using the "Pipe Transition Point Above Grade" and edit the text to state that it is a header location and point to one of the drip irrigation details that show that transition point/header.
- We identify the exhaust header by placing a manual flush valve and editing the text accordingly.

This method lets the contractor know if you are specifying a center feed or end feed header since now you've got the supply header (pipe transition point) and exhaust header(s) (manual flush valve) identified. You don't need to show the lines unless you are trying to identify the quantities as Jake stated. IMHO, a less cluttered drawing is a cleaner drawing. Communicating the intent is the most important key. Wouldn't you agree?
Attached is an example:
thanks Seaweed, we do a very similar thing, we just draw the header manifold and on longer/larger areas we add the end and or middle feeder PVC pipes. our details help to show typical examples of how to feed the zones but we find that by adding the PVC pipe symbol for headers we get a better result in the field. we were doing something similar to what you suggest but found that it let the contractor have a bit too much flexibility.

are you doing this as surface or subsurface drip line?

i don't think a simple bold line adds too much confusion, just a style and method we are using.

thanks for the feedback, much appreciated.

Bob
Bob,
I agree. Communicating the design intent is the key. I have found that just like any other business or skill, some contractors are better at understanding intent than others. I had one contractor ask why we were specifying plastic valve boxes for valves located in the street. IN THE STREET? He missed the note about the plans being schematic and that all equipment is to be located in the planter areas..... I'm so glad for the RFI, but are you serious? I suppose over explaining is better than having someone install a mainline and all of the valves under pavement.
Have fun Bob.
