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…

  • Previously I mentioned Listing Order. This post takes things up one level to discuss just what ends up where when a job is AutoListed. From the HydraCAD Manual / Electronic Help: It is important to understand how the Listing tags work in order to achieve a successful AutoList run. There are two types of Listing…

  • How does AutoList decide what order to list piping in? Here are the general listing rules that pertain to the order: Welded piping (whether lines or mains) lists before Threaded piping Welded piping is listed in alphanumeric order (specifically, the ASCII order) Per the ASCII order, numbers list before letters. Punctuation marks, including spaces “…

  • We’ve all seen this. You have a nice drawing in front of you, but when you do Zoom Extents (or Zoom All), your drawing disappears and you find yourself floating out somewhere near the (ex)planet Pluto. You select all around outside of what you want to see and there is nothing there. Sometimes you can…

  • HydraCAD has long been able to create a file that can be opened in the JCI/Tyco/SprinkCAD Fluid Delivery Time program. That program is required to open the exported file. Hydratec and SprinkCAD worked together to offer this tool. The file can be created from HydraCAD using a process similar to AutoCalc. The following is from…

  • Way back in the olden days of 2014 I wrote a blog entry on BIM LOD. Sometime between then and now they snuck in a BIM Level 350, so I figured it was time to revisit this topic. From www.united-bim.com  In the current context, there are six different levels of development that are defined by…

  • When a riser nipple is inserted a property is programmatically set identifying the riser nipple as a Line, Main, Arm-over or Underground for listing purposes. This can be ascertained by looking at the Properties of the rider nipple in question. Most of the time, the way it is set is perfectly correct. On occasion, however,…

  • So, Windows 11… The good news (for us at least) is that all our current versions of Hydratec software work well on it. I ran the update on my machine, and my already installed software worked just great. I have also run some of our install without a problem. What’s the bad news? Nothing is…

  • Taking into consideration the large number of sprinkler heads available, we decided not to clutter up the database and avoided predefining most of them. This means that you will often run an AutoList and find that the Miscellaneous tab in HydraLIST has a number of yellow highlighted head entries without a description. That is because…

  • Quick Assist is built into Windows 10 and allows for remote control connections to other computers. No downloads or other software needed! Type in Quick Assist at the Windows Search bar. You are given two simple options when it launches If you want to take control or see another person’s computer, choose the Give assistance…

  • I never knew about this option until Googling about it today related to a customer reported problem. The problem was related to an old AutoCAD bug which allows a build up of a great number of annotation scales. This will cause a fatal error at various times in a drawing session. But, it won’t cause…
