Using a Non-Standard Pipe Type in HydraCALC

  • This is the first in a series of posts on how to self-diagnose errors you may encounter while elevating your drawing to 3D or while running AutoCalc or AutoList. HydraCAD includes a number of tools to assist you with the diagnosis and correction of these errors, and these post will review some of them. The…

  • A feature added to both HydraCAD V50.4 and V51.4 allows you to break a head or riser nipple into a branch line automatically. Note the prompts when you pick Insert Head or Insert Riser Nipple: "Pick insertion point. Pick any point besides endpoint to break into pipe". Try it out using the NEAR Osnap or…

  • Q: How do you view Revit files without buying Revit?  A: From Autodesk – Download the Revit program and run it in Demo mode. Demo install can function as a viewer with no expiration.

  • 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…

  • 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…
