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…

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…

  • This post was prompted by a call from a long time customer (Hi, Debbie!). I found the following on another blog and it sounded interesting enough to repeat here: From Ellen Finkelstein's AutoCAD blog (a very excellent one, by the way) "I want to make sure that you know about 3 really handy commands that…

  • From a customer: "I started using the Viewbase command, which I learned from the H-Factor blog.  I love it, it makes pump details very easy to do.  My only question would be about certain block/details.  A lot of the time I use Revit models from manufacturers, such as Reliable.  I will download a 3D valve…

  • I ran into this one about two years ago and swore that I wrote a blog entry. Apparently not. I ran into it again today via a customer in the Bahamas (nice place, huh?). This virus is not dangerous or vicious, but it is really annoying. It causes an error upon loading HydraCAD due to…

  • SHIFT can do some SHIFTy things (sorry, I had to ). I found this on Cad Addict's website: SHIFT while drawing a line will lock the perpendicular inference. It is like a temporary activation of the ORTHO mode. If you press SHIFT, a tooltip with similar to the macro Icon of digital cameras appear to…

  • Once you 'go to 3D' in HydraCAD, you get a wireframe model. This is actually a Visual Style named '2D Wireframe'. If you would like to make a more professional looking presentation, you could apply a different Visual Style. To open up the Visual Style palette, type in VISUALSTYLES or pick the Visual Style button…

  • Version 51.11, and by extension, V52.01 added a new function named Bundle PDFs to the brand new Collaborate toolbar. This command will be renamed Create Submittal Pack in the next update (V51.12/V52.02), so keep an eye out for the new name. This command will scan the drawing an pull out PDFs for many of the…

  • HydraCALC has a special tool to help you figure out where in your system losses are occuring. The Graphical Pressure Display (GPD) is that tool. In order to use it, one extra step is needed – you need to fill in the column named Input Type This column specifies the role of each pipe in…

  • What is the status bar? It is that thing at the bottom of your drafting window that looks like this: Now, in my opinion, the icons are pretty, but I would rather have the words, so I don't have to think too much when I am changing settings. So, right click on any one of…

  • HydraCAD V51.10 (and by extension, V52) added a new function – Generate RCP Heads to the Cleanup toolbar. What does this do? From the OlderChanges.rtf document: (N)New command added (Generate RCP Heads) to help with the plotting of pendent heads for a Reflected Ceiling Plan. This command will generate a copy of any sprinkler heads…

  • Autodesk has created a reduced feature version of Revit (with a much reduced price) that will allow you to open Revit drawings, but not do much else. It will allow you to open Revit files from other sources and turn them into DWG files, but there is no ability for it to be programmed by…
