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…

  • We all like UNDO perhaps more than any other AutoCAD command. (don't you wish Life had undos? Of course you do, if not, yer lyin') Well, if you ever get the Must enter UNDO END when trying to undo, just pick our ESC button on the HydraCAD Utilities toolbar, and that will do the UNDO…

  • If you are sending us, or a coworker a drawing for them to AutoList or diagnose – how do you send the listing tag setup (the top 5 FIGs)? The good news is that you don't have to , they are part of the drawing as long as you are on 50.4/51.4 or newer. From…

  • When I first got my computer and booted my machine, I went go get a cup of coffee from the kitchen here at the office. When I came back, i could use the computer. Now, after a few years, I feel like I could get to Colombia and back with a cup of coffee before…

  • From a customer (Aaron at Dalmatian), via Bill, my coworker: "I spoke to you about an hour ago regarding the ugly mesh around all of the 3d objects when setting the viewport shade plot to 'hidden' with the model otherwise set to '2dwireframe'.  I’ve figured this one out and thought I’d share it with you:…

  • Does it take 20 minutes for you to copy and paste drawing entities? The reason is that probably have a bazillion SCALE LISTS as part of your drawing, thanks to all those that are parts of each XREF you have attached. Type in SCALELISTEDIT and pick Reset to clear them out. Note: If you reattach…

  • Many people use Bayspace to insert sprinkler heads and connect them with branch lines. Most don't know that you can also have Bayspace draw one pipe from the first head to the last head or draw no pipes at all. This option is on the second dialog box as seen below.   The One Pipe…

  • AutoCAD lets you modify your menus to add toolbars, modify them, make Workspace changes and so forth. BUT, our installs and updates will overwrite them, so you REALLY should save those changes. This is how you do that. In AutoCAD, workspaces, menu and toolbars are stored in a menu file with the extension .CUIX file.…

  • Sorry for the long absence. I was just helping wrap up to large projects (hint, hint) that are finally done! News about those next week. Some of you miss the old (pre-2007) double-click behavior whereas you got a full dialogue of attributes when you double-clicked on a block. AutoCAD changed this some time ago, but…

  • 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…

  • I have gotten two calls on this in the last two days, so that makes it a good blog topic. What if you have a pump and a tank, but no city supply? This one is simple: 1. End your piping with the reference point PUMP (any name will do, but be consistent) 2. Set…
