NX - Body not able to divide into two pieces

NX - Body not able to divide into two pieces

NX - Body not able to divide into two pieces

(OP)
thread561-195944: Extude cannot split target into multiple solids, Please Help
I have a iges model (Hollow from inside) which i want to cut into 2 equal pieces
But i have tried:
Split
Divide
Trim body
Extracting and then sew all the faces
But still every time it says bodies create into multiple bodies.

I am using NX7.5
I have attached the model for your reference - http://files.engineering.com/getfile.aspx?folder=7...

Please help me ASAP

RE: NX - Body not able to divide into two pieces

This is one of the very rare cases where the solid body is "inside out". On a normal/valid solid body, all face normals point out, away from the volume. On this one all(*) point inwards. If you use for example the Synchronous Optimize face feature, NX will reverse the normals into a valid body.
Probably also functions such as File - Export -Heal geometry will repair the part.

Just for fun, try placing a view of the model on a drawing and see how strange the result becomes.

* Use Information -Object and select some face-s, the arrow displayed should point out, not in.
( I did not check all faces, maybe 10 .)

Tomas

Thanks everybody for very quick response but none of the file attached is not opening in my UG.
Also i have 3 other parts to be completed so please let me know how to create split onto it.
Please list down some steps for how to do

RE: NX - Body not able to divide into two pieces

The file I submitted is NX7.5, don't know why it won't open.

To fix your file go to Insert> Synchronous Modeling> Optimize> Optimize Face, then select all of the body faces and and hit "OK". You should be able to split the body using the normal split command.

If that doesn't work, export the parts as STEP files (File> Export> STEP203) and either re-import them or open the STEP directly using File> Open and selecting the *.stp file type option.

mmauldin thanks for the details advice...

Is Optimize face command available in NX6????

RE: NX - Body not able to divide into two pieces

Synchronous is in NX6, but not "optimize face"...

Dear John,
Thanks for your help and paras solid model.I have got 3 more other models to do the same.

I want to know how it can be done in NX6.so that i could apply it in other 3 also.

RE: NX - Body not able to divide into two pieces

Sunnylooks,
if you read the thread above, you will notice that I have proposed the Heal Geometry option and that Mmauldin has commented on this and noted that the Heal Geometry works. I have now myself tried the Heal Geometry , in NX6, and again noted that it works.
Other users has reported that doing a Step Export -Import also repairs this model.

Is there anything more to say ?

Regards,
Tomas

RE: NX - Body not able to divide into two pieces

(OP)
Thomas your are perfectly right...but both the options are not working at my end...

RE: NX - Body not able to divide into two pieces

All I did was File -> Export -> Heal Part

RE: NX - Body not able to divide into two pieces

Sunnylooks,
When you use the heal geometry option, are you aware that NX will create a new partfile containing the "healed" body ?
The one you "exported from" will not be changed in any way, you have to open the healed partfile and use that instead.

Regards,
Tomas
