How to make a new model to a existing assembly ?

[12131444]

Hello (Simple question)

How to make a new model to a existing assembly ?  (Inside the assembly)

• Assembly->Create New, but what from there ? I'm not sure ?
• Now the new model is in "work part" mode... I pressed Create Sketch, but how can I select a plane withing the existing assembly when everything is greyed out but only the newly created model ?

• How to use the features of the existing assembly to create the sketches of a new model ?

Now:

1. I make the model outside the assembly....(Without knowing how to use the existing assembly as a reference to create the model. So no reference from it. I just remember different measures from my notes and from my memory...)
2. Then Add the model to the assembly...
3. Then Move it to the right place.

I Moved the coordinate system of the new Model and started the sketch from its Planes... Not the same though is there possibility to select the Planes from existing assembly ?

make sure that u set the selection scope to entire assembly

Ok. Does it form "a costant connection / relation" ?

So when I modify the reference part will the new model break down / corrupt giving error codes ?

• In 2006 people warned not to use other parts as a reference because this could cause problems later ? When these parts are modified...
• I'd like to avoid creating these kind of relations.

-> What is the best way to create a new model inside existing assembly ?

If you use the entire assembly connection you don't have a link between the face of the component and your sketch in the new component

if you want to create a link you can use the option "create interpart link"

this will automatticly create a link between the selected geometry.

or you can always use the wave geometry linker

Ok. these are all new things for me:
1.) "Create interpart link"...
2.) "Wave geometry linker". Used only 6 months NX at my work.

Oke,

wave geometry linker can be used to linked curves sketch faces bodies between parts.

if you doe this and the parent sketch is changed then will the linked face will also change. this has to be in an assembly structure.

See movie for a example:

Unable to play video. Please try again later.

so with wave geometry linker you will create first the linked faces before creating a sketch of extrude.

if you use the create interpart link NX will create the links for you when you select them in the extrude feature.
