  • Occasionally we get contacted by a customer who states that something is wrong with his drawings, but when they are opened on another computer, they are fine. If one of the usual suspects is not to blame, we then compare the AutoCAD settings on the ‘bad’ computer to a ‘good’ computer. AutoCAD includes an Express…

  • HydraCAD has a tool to generate a hanger point file to be loaded into a total station, and that file can include seismic brace locations as well. The command is located within the Create 3D Hangers command, found on the Hangers toolbar: Pick the Create 3D Hangers button to get to the Generate RTS Points…

  • Many larger sprinkler companies and fabricators modify their HydraLIST data – part numbers, prices, assemblies, pipe types, etc. It can get really tiresome to copy the HydraLIST data files to each users’ machine whenever data is changed. Enter the Master Data Location. To set this location to a common folder is really simple. Here are…

  • HydraCAD’s templates have layers built into them, as you are already aware. These templates specify properties of the layers such as color, linetypes, plot status, and line-weights, among other things. Many users are content with using the layer properties we have set as defaults, but what if they want to change them? What if they…

  • When you right-click on the Pipe Type field in the pipe input screen, you usually see a dialog box that looks similar to the box below. But, what if you don’t use some of those pipe types, or would rather display other ones? Pick the Options pulldown menu, then pick Edit Pipe Display Limits Here,…

  • Last year we added a new feature to HydraCAD that allows users to add Fittings, Valves and Backflows to the drawing in order that they may be picked up in AutoCalc and brought over to HydraCALC. The command is Add Calculation Fittings from the Calculation toolbar: Pick this command. This will display a dialog box…

  • My coworker Bill wrote this up, based on frequent requests for help with Pressure Reducing Valves: There are two types of PRV valves, so there are two ways to handle the calculation: Type 1 – Fixed PRV Three calculations are required for a factory set or field adjustable PRV: Static at PRV, System Demand at…

  • This idea is from long time customer and frequent good advice giver, Larry Howell at L & K Fire Protection in Marion, Illinois “I wanted to share windows file explorer libraries with the blog users, as I just discovered their usefulness. When choosing a place to save calculations and stock listing files, the default does…

  • I had a customer contact me today because he was unable to use any of the internet spawning commands in HydraCAD including Send an Email to Hydratec, Hydratec Website and Hydratec Support Blog (this blog). The cause of his problem was that a browser was not associated with HTML files. Instead, some other program was.…
