Trim in NX5 with cone or cylinder like NX3

[PSI-CAD]

Since NX5, it's no more possible to trim with a cylinder or a cone inside the menu.
I found a work around with the copy/paste function
- I open an NX3 part with a trim by cylinder feature
- I select this feature then ctrl+C
- I create a new part in NX5
- I create a sample block for example
- Then ctrl+v to paste the trim
- I am able to modify the trim parameters

It's also possible to create an UDF to simplify the procedure.

But does anybody have another solution or a grip program to retrieve this function ?

Thanks in advance

The reason why you can do that is because we continue to support editing legacy features even when creating them has been obsoleted.

As for the removal of the 'on the fly' creation of the primitive 'shapes' used to trim the original body, while that might have been handy at one time, back before feature-based modeling and expression-driven parametrics, in a more modern system, it's best that each shape has it's own feature with it's own parameters. Note that just because you can explicitly edit the 'size' of some 'shape' does not automatically make it Parametric since that requires the support of expressions, which in the case of the NX 3 Trim Body, the 'shapes' do not. Also note that the origin and orientation of those 'shapes' are not associative, another hallmark of a fully-parametric model.

Hi John,

I already knew the reason, but i would like to know if there is another wa more simple to retrieve this function like a grip programm aven it's not parametric.

Thanks in advance

I'm fairly sure that you could create that geometry with a grip program since it is very simple geometry. It would however need to live somewhere in the file as actual entities.

I never used that trim method back in NX-3 anyway because I prefer to have the entities somewhere where I can see them. I'm very visual in my thinking and hate to have to analyse a trim that somebody else has created which I cannot see the effect of.

Therefore for the small number of times that I would use such a trimming operation my preference is to simply create the trimming geometry and use it to trim. I then simply place the reference geometry on another layer so that it is out of the way.

Anyone later using my model will find it much easier to figure out what I have done.
