Hello beloved community,

 

trying to implement some cooling channels i stumbled upon this "merge" issue here.

I coudn't find anything related in the forum.

 

The single cooling channel in the back should split up into two identical ones and after a while merge again (see pic).

 

I used offset curves, bridge curves and studio splines with tangent constraints and setch points to get the curves needed for the sweep.

 

Using the variational sweep (VS) tool it won't allow the usage of "intersecting" curves or "multiple loops".

I tried "composite curve" to somehow merge the curves beforhand but VS wouldn't take it as input.

 

When i use several VS i get a non symmetrical connection as you can see in the picture.

Going this particular route (using several VS) will lead to ramifications later on with edge blends to smooth out the merging tubes and to mesh the whole thing in the end for simulation.

 

Is it possible to implement this kind of cooling channels in NX in a clean way?

 

Any help woud be greatly apprechiated.

 

Regards

Hello,

I am working with NX 10 within routing mechanical piping module.

I want to do pipe stress analysis and have problems getting information of all parts/fittings extracted into a PCF. If I am using NXs database it is working, but I also need to do this with my own parts such as fittings, valves etc. . I already tried to look up attributes defined in NX-database-parts and added them to my parts, but still my part does not appear in the PCF created.

Now, I am wondering about how I can model parts so that their information can be exported and appear in the PCF. I hope someone can help me in this case.

Best regards

Hi All,

I have a model that needs two configuration. Customer has requested me to create base model which has less features and a premium model which is having features built on base model. Now I would like to link the premium model to the base model,i;e premium model should get updated when the base model updates.

For examaple:

Base model has features : Body-extrudes-hole-fillets

Premium model has features: Base model(Body-extrudes-hole-fillets)-switch cut-outs(Feature grouped)-added bosses(feature grouped)

Can I use part family for this??. If YES how..

Any suggestions would be appreciated.

Thanks, 

Devaraj

Hello, sorry for asking this kind of nooby question here, but just I can't really find any to solve my problem,

Actually, I'm using NX 10 sheetmetal to simulate a strip of how a sheet metal product forms in sequence,

and I want to design my own product now, but just can't change the thickness when I clicked the "TAB", it always shows 3mm automatically. Do you guys have any ideas about this ? I saw a post kind of about this, but it wasn't solved. So, I'm wondering if anyone knows about this.

 

Thank you.

When doing a save as new revision is there a setting to have the displayed part change to the new revision?

 

For example:

I have part X revision 1, I do a save as new revision to go to part X revision 2. But it leaves the revision 1 displayed.

 

Thank you,

Hi there,

 

Is there a way to change the number of decimal places of the attributes?

 

For instance, I'm using MY_MASS linked to NX_MASS, so when I import it to the drafting the NX show every decimal places possible.

Hi there,

 

Anybody knows how to map approval user like a approval date?

 

I tried copy this:

"Approval_Date" : ItemRevision.Job.SIGNOFF(Designer).decision_date /master=iman /description="Approval_Date"

 

And map this:

"Approval_User" : ItemRevision.Job.SIGNOFF(Designer).decision_user.id /master=iman /description="Approval_User"

 

But it isn't works.

Hello,

 

Is there a way to suspend (or speed-up) assembly cut updates?

Everytime I try to update an assembly with an assembly cut in it, it takes forever.

 

I have cut a lot of solid (around 500) in this one and everytime I want to make a change, it takes around 20 minutes to update!

Hello, people, sorry for asking this kind of nooby question,  

I am now trying to make a simple sheet metal product which is supposed to be too easy to have any problems,

YET, I can't do this kind of bending on my product only with "Bend", it seems like it has some kind of restriction or stuff like that. 

This pic below is to show the bending that I want to make in NX 10, but it's actually under "PTC Creo" enviroment.

Thanks a lot.

Looking for videos/introductory tutorials for below topics related to Ship Design. I do not need detail training but any material which can help to start. I have seen very few videos (couple of minutes) in Design Knowledge base which is good but not sufficient. I tried NX Documentation, which is beneficial once I know how to start and then read to get more.

 

Any suggestions or pointers?

I get this question fairly often, and I always end up going to a very old work around, ie making a sketch in the view, to create the hinge line.

 

As you can see, there isn't a hinge line, that will project the view, to show the bend angle.  Users often ask "why can't I jusst pick one of the bend lines, and have it project 'along' that ?"

 

So have I missed the boat?  is there a better way to do this, besides creating a hinge sketch?

Hello I have a problem with a current drafting I am working on. The part I am drawing is a square mount with some holes in it ( you can look at the professionally made drawing that is maid in paint that I attached because I am currently not at my work and therefore I don't have access to nx right now). The problem I have is that when I create a section view of the 2 holes to make them visible. But since the holes are on an angle on the workpiece I can't get the view to line up or fit in the current draft. Is there anyway to get the same sectionview and rotate it 30 degrees so it will be parallel and I then can place it where I would want it to be ?

(The sectionview is needed because the holes are complicated)

Hello, I am an fairly advanced user of NX but I have trouble recreating the surfaces as depicted. Could anyone please help me and enlighten me how to do this? Given that NX can't snip surfaces ending in one point (like the nose section). And also can't change degree of these surfaces, when they are created using through curve mesh. I am only able to recreate similar surfaces but the adjacent poles (highlighted in the image) are never the same as the ones in the adjacent surfaces (although the surfaces are G2). Is there any trick to lock the poles to the adjacent surface edge poles (same number and position) when creating a new adjacent surface (using studio surface or through curve mesh)?

 

(The Images above are parts I am trying to recreate. Not the surfaces I have created.)

 

Thank you.

Hi Guys,

 

Thank you so much for my prevous questions and it was very very helpful. 

 

I only for now need to find how to design cooling system for Plastic Injection Molding part.

I understand cooling channel what will be diameter rule from part dimension, what baffle from part but confusse me how to make cooling channel layout around part.

 

Is there any option in NX where inside of NX they show me suggestion approximately cooling channel layout for my plastic part , or do I need to make cooling system channel alone ? 

 

Any option in Mold Wizard for that or without Mold Wizard - some other suggestion ? 

 

 

Thanks in advance

Hello,

I'm looking for a matrix or maybe some other form of document that has the information which version of NX (NX Mechatronic Concept Design) can be connected with which version of TIA Portal.

Great thank you for any help.
