Adding Hanger Types to HydraLIST

If you want to use a new type of hanger, or are a fab shop that gets a job from a contractor that uses a hanger type that you do not have, it is easy to add that new hanger type to your own machine. A hanger is an assembly, and an assembly is just…

Using a Non-Standard Pipe Type in HydraCALC

A customer called today asking how to enter a 1″ black plastic underground pipe for the calc. This particular situation sounded unique enough that I did not tell him to add that pipe type to our database, as I would have if he expected to see this pipe type used repeatedly. I told him to…

  • Don't use Format->Layer Tools->Layer Delete on any of Hydratec's stuff. I fact, I don't recommend using it in architect stuff, either. Here's why – besides deleting everything on the selected layer and the layer name itself, it also redefines all blocks that have a foot in that layer and remove those parts that do. An…

  • Unbeknownst to many, HydraCAD has a command (shortcut CAP) that will change many properties of attributes within a block. I have used it mostly for changing the text style used or the color (usually set be the background author) of attributes, but it does more than that. This command is also available on the HydraTools->Modify->Attributes…

  • I posted about this before, but not concerning a wholesale replacement of your blocks with tool palettes. If you have a large library of your own details and blocks, you can convert entire folders at a time to tool palettes by using the Design Center: 1. Press CTRL+3 to open the tool palette (if not…

  • From a customer: Art, I have a couple questions about V50. If I make a 3D detail will I be able insert it into navisworks similar to the solidpipes? Can I integrate 3D details with all of my piping? Second, my understanding of BIM is that upon completion the building management/owner would be able to…

  • In V50 we have created tool palettes to not only allow you to drag and drop details and blocks onto your drawing, but to also make it easy for you to add your own blocks. In the past it was difficult to do this because we used slide files and menus – both were not…

  • The updated Purge All Unused Layers and Blocks (PURG) in Rev 2 of V50.01 goes further, fixes more and is easier to use than our older command. The new command purges the drawing, runs an AUDIT and then purges it again. Try it.

  • A wooden roof with dormers – many of us see the all the time, but how to label it so that HydraCAD can elevate it properly – that is another thing. The drawing below shows how to handle this. If you download and install the HydraCAD V50.1 Rev2 update from our website, this drawing will…

  • Lets say you have a ton of branch lines with retrofitted armovers that go off in all directions. There is no easy way to size these, right? Try this: Size all your branch lines by selecting the Lines option in the Size Pipe toolbar. Also select Use Directional Filter and select either Horizontal or Vertical,…

  • From a customer: Art, we are doing a hospital that has say 1500 heads per floor x 6 floors on armovers. When we go to tag the piping, the branch lines are say 1.5” the arms are 1” and the mains are 4”. Since the mains are on a different layer, they are easy to…

  • For the last six months I have put up with the fact that when I pick the New icon, I don't get the Start a New Drawing dialog, but instead get thrown into the 3D Land of Gray template. The only way around this for me is to pick the File pulldown then pick  New…
