Unblocking a Group of Files

After downloading a file, it is often Blocked. You must right-click on it, pick Properties and then check the Unblock item: But doing a dozen or more files gets old, real fast. I just learned a way to Unblock a batch of files at once. It involves using PowerShell, a Microsoft tool that is a…

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…

  • Revizto is BIM software that competes with Autodesk’s offerings, specifically, Revit. Revizto can open HydraCAD drawings, but some information may not be showing up properly. These two HydraCARD Knowledge Base entries should help you get by the issues we most often hear about: When reading a Persistent Model drawing in Revizto, the units are not…

  • HydraLIST has the capability to store an Alternate Part Numbers for each HydraLIST part, along with our standard part number. Why is this important? Because many fab shops, either independent or sprinkler company based, already have their own part numbering scheme. This ability allows our customers to continue to use their own part numbers when…

  • As new products are released by manufacturers, we add them to files that can be imported into HydraLIST. Why don’t we add them to the HydraLIST database directly? Two reasons: We don’t want to overload the database with thousands and thousands of items that may not be used by most of our customer base Many…

  • Customer X called today to ask if he could reduce the width of the polylines that are part of our DefLines (Drop Windows, System Boundaries, AFF/BTS, etc). There is no setting in our programs to do so, but there is an easy way to change them after the fact. After some chatting back and forth…

  • So, my co-worker (who shall remain nameless) sent me an annotated drawing with notes on how to properly model trapeze hangers for coordination. The notes were written as individual lines of text. This annoys me: I like working with MTEXT so much more. MTEXT allows for formatting, fonts, underlining, numbering and more. I thought I…

  • This from a customer in Sweden (paraphrased). This in metric, but the math is the same in US units: On the Fittings Used Summary, it says that a 65mm Tee has the equivalent pipe length 3.8m but in the calculation says 7.497m. And it´s the same for a 65mm 90 degree screwed elbow…the equivalent pipe…

  • We have an ever-expanding repertoire of support options. Here is the menu: For All Programs: HydraCARDs: A Knowledge Base of all known solutions to problems users might encounter can be accessed from the HydraCARDs shortcut on the desktop or this link: HydraCARDs This blog has entries for hundreds of topics on all of our programs,…

  • Occasionally users may get a ‘Job has gone 200 or more passes without balancing.” error message. This means, usually, that there are disconnected pipes in the job (pipes that may have flow in them, but do not connect to the piping between the Remote Point). You can try picking Yes to have it continue to…

  • We regularly update the HydraCALC database to add and make changes to fittings, pipe types, valves, backflow preventors and technical data sheets in PDF format for all of these. We make this database available for download in the Customer Support area of our website, which can be found at www.HydraCAD.com. Enter the Customer Support area…

  • From a Customer: “We’re engineers. As such our expectations for plans are a little different than installers. We need to use clear, consistent 2-dimensional symbols and simple lines to represent pipes without fittings. Right now all of our projects are showing top-down 3d models in plan view and every single pipe fitting. This makes it…
