Thank you for that tip Ivan.

Hi Ronald, Thank you for your response. Sadly, I don't have license for routing application. Is there any other way where I could at least make the lengths as close as possible other than by trial and error? Toost, yes. They make heat exchangers with multiple helical tubes. But I think it is...

Hi All, I have two helical pipes with same axis. Each pipe is made up of two different helix: One large diameter(outer) and one small (inner) separated axially by some distance. The two helices are joined by a spline. I am trying to join the helical parts of each pipe such that the lengths...

Hi Tomas, That's great!! Thank you for your help. I had some free time on my hand so tried building the model again. It works with the initial way that I tried(I guess I modeled it weirdly before). But its also nice to know another way (your way,which is easier I think). Do you think it is...

Its is a single part.

Hi all, I am trying to find the flow volume of a part that I am working on. I can find the volume without including the four features before the (last) unite boolean operation using 'delete face' and 'all but selected'. They contribute towards the outlet. But with the outlet I somehow mess it...

Any suggestions ? I don't know if it just a visual rendering issue or something that I am doing wrong.

Even I think so. When I try to measure it, the distance between the edges is zero. Same thing in FLUENT. But it still considers them as separate edges. But if that is the case, I dont know why it changes when i make it a part (unite) of the main solid. It looks better with aligned edges. I...

Hey cowski, I did try that before. It looks good as long as the rib and the cone are combined. As soon as I trim it, it becomes the same as before with the edges not aligned. This is pretty weird. I have also tried revolving a thin surface over the original part. It just doesn't align. Thanks

Hi Jerry, Thanks for the advise. I can see it works but it is still part of the cone. Can I anyway make it a separate solid/entity? I had the same issue with extrude. With unite boolean I have similar result. I would like to have the cone as 1st and the extrusion as 2nd solid. Thanks!!

HI Everyone, This is my first post and I am new to NX. I am try to extrude a surface on a part and eventually export it to fluent. I have attached the file and images of the part before and after the extrude. The issue I have is that the edges are not aligned after I extrude. To be specific...
