    Dimensioning Set of Holes on From Flat to Angled Plane

    Let's say I have a thin sheetmetal part with 3 holes, labeled Hole #1, #2, and #3 in the attached picture. As shown, Hole #3 is located on an angled plane. It is important that Hole #3 is dimensioned to Hole #1. Using only linear dimensions and calling out what the angle is, how do I accomplish...

    Datum Selection for Block Supported by 3 Pins

    I am designing a simple block that is supported by 3 pressed-in spherical/rounded head pins. We are using these 3 spherical pins to accommodate the irregularities on the surface that this block sits on. If the pins were not there, I would choose the bottom surface of the block as datum A as...

    Screw Material to Prevent Galling on 304 SST Threads?

    Currently, we have regular (304 SST) Heli-Coil inserts on the substrate we are fastening to. Most of these substrates are installed in the field already so changing out the inserts is not an option. Some of these substrates also have Nitronic 60 inserts. Due to cleanliness purposes, we cannot...

    Modeling Orifices in 1D Duct Flow in NX Advanced Simulation Thermal/Flow?

    I was wondering if anyone knew how to properly model a restrictor or orifice in the 1D duct flow mesh in the NX Thermal/Flow package. I've tried doing it using a mesh with a smaller diameter acting as a restrictor, but the results do not match up with an existing result that was gathered...

    Stuck NPT fitting in pressure regulator

    I have a pressure regulator that has two female NPT ports (inlet and outlet). Silly me forgot to put teflon tape on the male NPT fitting and tightened the fitting all the way in. Now it won't budge when I try to pull it back out. I don't want to buy another regulator as this one is relatively...

    Custom Measure in Simulation?

    I'm currently using NX Advanced Simulation right now. I'd like to make a custom "measure" or result in the post-processing. I have a result that measures velocity already. I can use that result to derive the result I want. How do I do this?

    Opening the Part/Modeling file in Simulation?

    I'm pretty new to NX so excuse the newbie question. I'm using NX 8 and whenever I open up a simulation file (.sim), it opens up the sim and fem file perfectly, but does not open up the .prt file where the model is located. I would like to open this file up to make some changes to the model. Is...

    Invalid LBC Neutral Name

    I'm currently using NX Flow for NX 8.0.0.2 and I'm trying to define a duct flow boundary condition. However, when I select it, an error pops up saying "Invalid LBC Neutral Name". What does this mean?

    NX Flow - Setting up a mesh and analysis for a general pipe?

    I'm new to NX Flow/Thermal. Basically, I want to create a general pipe or tube or something in which I can just input the length of the pipe, the diameter or cross section of the pipe, and other various properties. I believe in a general case this would be quicker than creating a 3D model of a...

    Internal error when trying to save?

    New NX user here. I've used Pro/E for a few years but that's irrelevant here. Whenever I try to save my .prt file to any directory, a dialog pops up and says "The following parts failed to save causing the overall save operation to fail". Below that will say "While saving...

    Parallel flow pipe network help

    Let's say I have a simple parallel flow problem as shown in the attachment. The flow is pressurized and the downstream of the return goes back to a piping system that is negligible. It does not vent to atmosphere. I've tried reading up on the subject, but I got stuck at a certain point. At...

    Designing a closed loop recirc cooling system

    Hi all, I'm doing a project right now which deals with designing a closed loop recirculating system using water to cool multiple components. However, this post will only deal with the fluids portion. Below is the diagram of a very simplified system. Note that the areas marked red are 90...
