  • What is LOD? It is 'Level of Development', a BIM pseudo-standard that specifies the level of completeness of a drawing/model. HydraCAD is capable of fulfilling all these levels, although most contracts (for now, at least) specify LOD 300 as the current goal. The following is from KalBlue: "BIM has been outlined into five levels.  These…

  • So, you've drawn dashed/dotted/hidden lines in Model Space and they look just great. But, you go to Paper Space and they are all solid. What is going on? The setvar PSLTSCALE is what is going on.

  • If you have a large drawing, we have long recommended that you use System Boundaries to break up the drawing for processing. But what if the system to be calculated stretches across other systems? You can still use boundaries, just use more of them, and make them isolate the main (more or less). See below:…

  • A tip from Joe O. at Troy Sprinkler: I just came across something really cool that I did now know and thought it might be a good one to pass along. I wanted to copy objects and then rotate the objects.  Essentially having the same group of objects but rotated at a different angle.  It’s…

  • A customer asked if there was a way to change the color of HydraPipes to red for the Navis coordination drawing. There are two ways to do this: Option 1: After you go to 3D, select everything in your model (yes, everything) and right-click and pick Properties. Then, pick the top drop down list and…

  • Double riser nipples were a long asked for improvement that was included in HydraCAD Version 50 when it was first released.The dialog associated with this command does not generate too many questions, probably since the graphic helps make sense of the options available: Once thing that does generate questions is how to go up one…
