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…

  • Somewhere around 2003 the internal diameters of CPVC pipe changed, based on manufacturer. Prior to 2003 our database had CPVC dimension published by IPEX Blazemaster  (.884, 1.109, 1.4, 1.602)   In 2003 we updated the database to match data published at the time by Tyco, Spears & Harvel (.874, 1.101, 1.394, 1.598) Looking online today…

  • My coworker Paul noticed yesterday that his files were not getting sorted in Explorer like he was used to seeing them. Those that started with numbers were no longer in numerical order, at least not the way he wanted them. He dug around and found a Knowledge Base article on the Microsoft website. Sort Order…

Some users, however, don’t like the fact that this version fades and locks the layers chosen instead of turning them off. This, like most things, can be changed: 1. Pick HcadTools->Layer Control->Layer Isolate   Note the command line says:…

  • Suppose you want to place notes on the fabrication report denoting how certain hangers are to be assembled, or made. Notice the Fabrication Notes column on the Hanger tab of HydraLIST. Type in up to 32 characters of a note to be printed on the Hanger reports. If you have a common note to be…

  • The AutoCAD Join party, that is. I confess I did not know this command existed until a customer in NC pointed it out last week. The JOIN command is found on the Modify toolbar between Break and Chamfer. It will join a line, polyline, arc, elliptical arc, spline, or helix. The first three are the…

  • Some people don’t like seeing the commands written out near their crosshairs. Personally, I love it because I don’t have to look down at the command line. But…. To turn off the crosshair command prompt, right-click on the DYN (Dynamic Input) button and pick Settings. Then turn off the Show Command Prompting… If you lose…
