NX 2212 - Sheets from curves.............. 6

[CAD2015]

Hi,

How could I create sheets from the curves shown in the attached picture?
Which "Surface" tools would be the best?



Thanks

 

[DrPriest]

Basically, I would use Extrude, Draft, and blends, based on what I would measure from the curves. Now if I had to use surfacing for some reason, I would go with bounded plane for all that is planar, and the blends would be through curves mesh with tangency to the adjacent faces.

If a had to do it with surfaces?
Bounded plane on all of the planer areas, then enlarge them and face blend.

Thanks for your prompt answer. It helped me complete the task.
Quick question: You mentioned "Extrude, Draft, and Blends"; but all of them are tools for solid creation..................!
Was it an error? Could you explain what you meant?
Also, how would you create a solid out of the curves given?

Thanks a lot!

Rob,
How would you enlarge the Bounded plane feature?

P.S. Would the Administrator accept me to attach an NX file, as a sample?

Thank you!

Using the enlarge command after bounded plane.
You could also extend the lines and extrude them using the lines as vector

Thank you!

I assume the picture is an illustration to the question? Else you would do this specific model in 2 features, 1 extrude and 1 blend.
There is a very old command Sheet from Curves, ( + 30 years old command , it will not be updated.)
It will create all planar sheets in one go, but non associative and as separate sheets. Classic surfacing.
If you like more work, bounded planes , it's one surface at a time but can be created with holes and associative.
If you do this oversize, or as mentioned, create the surface and then use the Enlarge feature you can use the Combine feature and "find volume".
Then it's regular blends on that volume.

If the curves are already there, you could use N sided surface. Or you could also use Fill surface also. A couple other options if the curves already exist.

Well, since I don't know the context surrounding your task at hand, I would normally go for Solid modeling. I would try extrude the lower section, then draft the left planar face, and then blend the edges that require blend on top.

Also I like the following approach:

If a had to do it with surfaces?
Bounded plane on all of the planer areas, then enlarge them and face blend.

Instead of enlarging the surface, you can just use the "Extend Sheet" command with the "sheet edges" selection intent. Since these are surfaces created from a bounded plane, you shouldn't encounter any issues.

As usual there are many ways of achieving somewhat the same result and in many cases exactly the same result, it all depends on what is the intent of your design as it usually shapes and the designing strategy we follow.

No need to enlarge the bounded planes, Face Blend will span the gaps:

Thanks for your reply.
Make me a favor and send me a video/movie of your model.
It looks very interesting, and I do not want to lose your lesson.
(I do not think that the administrator would accept NX file sharing....)

Thanks a lot!

(I do not think that the administrator would accept NX file sharing....)

If it won't allow you to attach a .prt file, try zipping the file first. That usually works.
However, with Siemens putting out a new major release every 6 months, it is becoming less and less likely that we can share files as everyone seems to be on a different release...

 

[mmauldin]

Zip attached.

Great, thanks a lot!

How would break(disconnect) the link between the grey model and the yellow one?

 

[mmauldin]

You would need to recreate the Pattern Geometry but with associativity turned off.

 

[Toost]

Is this the real wireframe model you are asking about ?
Or are you trying to learn methods to apply on real model ?

For some reasons, the associativity on my NX is by default inactive.




But is it don't matter; I just wanted to know the fact.

Thank you so much!

Hi Toost,
Thanks for your inquire.
Yes, I am trying to learn methods to apply on real model.
