  • If you have a large drawing, we have long recommended that you use System Boundaries to break up the drawing for processing. But what if the system to be calculated stretches across other systems? You can still use boundaries, just use more of them, and make them isolate the main (more or less). See below:…

  • A tip from Joe O. at Troy Sprinkler: I just came across something really cool that I did now know and thought it might be a good one to pass along. I wanted to copy objects and then rotate the objects.  Essentially having the same group of objects but rotated at a different angle.  It’s…

  • A customer asked if there was a way to change the color of HydraPipes to red for the Navis coordination drawing. There are two ways to do this: Option 1: After you go to 3D, select everything in your model (yes, everything) and right-click and pick Properties. Then, pick the top drop down list and…

  • Double riser nipples were a long asked for improvement that was included in HydraCAD Version 50 when it was first released.The dialog associated with this command does not generate too many questions, probably since the graphic helps make sense of the options available: Once thing that does generate questions is how to go up one…

  • One often overlooked feature of the PERPendicular object snap is the ability to line up an object (such as a head) with other objects (other heads). To wit – the two heads below in the Dispatch Office are not lined up with the head plan north of it already piped. How to line up these…

  • Using a drawing scale other than 1/8"=1' or 1-100, you may notice your riser circle or text is too large or too small. This is how you correct that: 1.Type in 3MO or pick the 3D Modeling Options button from the 3D Modeling toolbar. 2. Pick the Restore HydraCAD Defaults button. This usually does it.…

  • AutoCAD 2013 introduced a new feature – Select Similar. It does just what it sounds like: 1. Pick an object (line, head, riser nipple, whatever) and right-click 2. Pick Select Similar from the menu that appears You can now do whatever you like with this selection set. You could Move it, Copy it or change…

  • A customer called yesterday and asked how to get rid of the little window that pops up when you hover over an item in AutoCAD:   After some Googling, I came across the subject as a post in Ellen Finkelstein's great blog. Type rollovertips on the command line and press Enter. Type 0 and press…

  • This entry outlines a little-known feature of AutoLine. Let's say you have large bays with irregular spacing and you have spaced heads throughout those bays, and now need to connect them. Like this: Draw the branch lines from the nearest head, to the furthest head, without stopping at the heads in between. Do this for…

  • This entry combines a little-known frature of a very common command (BaySpace). Let's say you want to insert heads and branch lines, and these heads want to be on armovers: 1. Use BaySpace to set parameters and pick you bay points as usual, but this time, select One pipe from the Draw: drop down list.…
