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…

  • There are many ways of adding loose material and kits to a HydraCAD drawing in order to get them listed. Some are old(er) and many are newer. All of these are on the Listing Toolbar. These do not need to be attached to pipes or sprinkler heads in order to have them list. They simply…

  • From a customer: “I have a question about modifying hanger symbols. Here’s the issue, many times the Lister’s complain that our plans are too busy, because pipe diameters lay over hanger numbers, etc. I know we can use the auto cleanup but I really want to eliminate the hanger # & either modify an existing…

  • If you have a drawing with paragraphs of text all written in individual lines, you may find it troublesome to change the fonts, size of text, add formatting, or, heavens forbid, adjust the room the paragraph takes up. These individual lines are composed of old-school text tools like Dynamic Text (DTEXT), or regular text (TEXT). Multiline text…

  • Some couplings result in a 1/8″ or more pipe separation, after they are added to pipe. On long runs of pipe, the multiple separations accumulate, and result in a pipe that is too long overall. For example, a run of pipe with 16 couplings can result in the pipe creeping 1/8″ per coupling for a total…

  • Many companies keep their HydraLIST database pricing current, at least to the best of their abilities given how often prices change. If you enter a part number into HydraLIST, the pricing gets pulled up when the list is processed. If you use certain parts regularly, it makes sense to update the HydraLIST Database with those…

  • From a long-time customer and friend: ‘I had a question about center to center dimensions on pipe. We do tons of CPVC, and the ½” increments aren’t necessary. Can I force 1” increments on the center to center dimensions?” This can be done by setting the default drawing pipe dimension rounding to the nearest inch.…

  • I had no idea this command existed, but found it when looking for a better way to rename a layer after a customer reported an error while running an AutoList. The cause of the error was that the pipe block layer, SPRKDATA, was built in the drawing as sprkdata (lower case). While may of HydraCAD’s routines…

  • Say you need to select all 1″ riser nipples but don’t want to go through a large drawing looking for and selecting them individually. How to do that? This way: 1. Select all items in the drawing. Alternatively, you could just isolate the riser nipple layer and select those 2. Open the Properties palette by…

  • So, you want to have an area carved out around sprinkler heads so that other trades don’t impinge on your space (yeah, good luck with that!) but aren’t sure how. Well, It’s pretty easy – what you need to do is to edit some of our sprinkler heads and basically draw a ‘cylinder’ around them.…

  • A customer we were training recently wanted to know how to create 3/8 and 5/8 fractions for use in hanger details. The wanted to know if we have those in our fonts. We do not. However, AutoCAD can automatically generate those, and any other fraction you can dream up, using the MTEXT command (not TEXT). If…
