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...
@ KENAT
Will do. I'll also look at ASMEY14.5 as well.
@pmarc
That is a good question. I have not decided yet, but I was thinking of using the surface profile tool with a basic dimension the bottom surface relative to datum A (aka the 3 points that define datum A).
Thanks all for the quick replies!
As mentioned by drawoh, I don't care much about the bottom face as long as the pins stick out from that bottom face as equally as possible.
@ pmarc: Correct. These 3 pins are pressed into the block to create a single part. The tips of the spherical pins will...
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...
Coreypad: What are the disadvantages of using PTFE coated screws? I was unable to find some solid data on the wear rate of these things. Some of these screws may have to be removed/installed frequently. I know it depends on the coating thickness as well as curing temp and other factors, but I...
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...
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...
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...
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?
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...
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?
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...
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...
Last question (which may be quite silly to many experienced engineers), but like the flow, is the inlet pressure also distributed at the first junction? Or does pressure remain constant until there is a head loss due to a fitting etc.?
Thanks all.
Without using the Cv, can I just keep entering estimates for flow rates in each branch in my spreadsheet until the pressure drop of branch 1 and branch 2 are equal? I tried it just now and although they're not 100% exact, they are quite close. I understand that this takes a lot of...
TD2K: Thank you for the input! I am indeed using Excel.
Do you mean to just treat each of the lines separate from each other first? (as if there was only that line in the system and not the other one). If so, I've already calculated the pressure drop for each of the individual lines in Excel...
