How to model this ?? 4

Hi

i am not able to model this 2D drawing.. pls check the attachment
and help me

What version of NX are you running?

Just one possible method, there could be more ways.

I would create the helical arc, and then copy them in a circular manner. From there, you could use the "Emboss" function.

Depending on the version of NX being used, this could be done in NX Sheet Metal.

I am using nx 9

The 2D drawing leaves a bit to the imagination, but attached is a one way to model something close. I tried several other methods such as modeling the overall body, such as a swept solid and adding cutouts, but they all had problems with missing faces and such when the blend radii were added.

Dear mmauldin, i cannot open the file you uploaded its having 0 byte size.. can you check it again

 

[mmauldin]

I was able to download and open it, but here it is again.

Hi Mmaulkin,

How did you create the spline?

 

[mmauldin]

Insert>Curve from Bodies>Extract Curve>Isoparametric Curve

Brilliant mmauldin....

Awesome sir.. thanks

Attached is the sample model I created in NX 10.
I think it is pretty close to what santhire wants.

Thanks,

Bryant

Hi Bwsh

I cant open it in NX9,
is there anyway??

 

[Bwsh]

Re-installed NX9 and re-modeled in NX9.
Attached is the model.

Thank you so much Bwsh..
its just what i wanted
i would like to know what is the difference B/n Pattern feature and geometry.

 

[Bwsh]

sk258013, as the name implied, i think i know the differences.
I would leave to the experts in this forum to clarify them more correctly.

Do we need to complicate this model this much ?
If i look at the image from Bwsh, it's a hollow cylinder , with diagonal grooves.
Modeling this as a "cylinder" instead of sweeps should simplify the task.
( Extruding a circle will create a cylindrical face as well as using the feature "Cylinder".)


- If the end result should be cylindrical, and we do not have a purpose creating a far more complex face such as a helical B-surface, Go cylindrical.


Regards,
Tomas

Bwsh uses a method I like, although the cylinder option is my favorite.

As John hinted before, how can this be done in sheet metal ?
I know it is not possible to roll form a cylinder from sheet (not in NX9 that is).

Here is another take on it. I have used Bwsh part file but created a cylinder and hollow.
