The H-Factor

Say you have a standard return bend. A 1" 0-4 (CC) feeding an armover that feeds a head. It looks something like this:

Now say you need to offset that head to the next tile up, but want to keep the same connection point to the branch line. In short, you want it to look like this:

Here is how you do it:

1. Using grips, select the head and pipe and drag them to the new location

2. Pick the pipe and the unmoved pipe dimension. Select the middle grip of the pipe dimension, thereby making it the 'hot' grip (this is the insertion point of the dim) and put it near the moved pipe. Do NOT put it exactly at the midpoint of the pipe

Result:

3. Pick Update Pipe Lengths (UP) from the Size Pipe flyout to recalculate and reconnect the pipe size:

4. Now, double-click on the riser nipple. This will tell you to select a vertical pipe. Pick the riser nipple. Pick one of the SPIN buttons repeatedly until the outlet aligns with the pipe, then pick APPLY:

Note that you can change the type of riser nipple as well, from an RN to a Dn to drop down to a head, for example.

You are now done. The next release of HydraCAD (V51.11, V50.11) will have the added feature whereby the Update Pipe Lengths command will also rotate the pipe dimension to match the angle of the armover.

These steps can even be done if your armover pipe size has been shrunken (Scale Pipe Sizes Down command on the Pipe Size flyout [SCLSIZE] or through AutoLine) or hidden (Hide Attributes command [HAT] or through AutoLine)
