MIRROR ISSUE

MIRROR ISSUE

MIRROR ISSUE

(OP)
Hi,

I´m once again in great strugle with mirror that i need to do in ug:

I am a moldrawer an i need to do 2 mold with mirrored part geometrie.
in this case most of the mold will be the same, some will be mirrored (core cavity) , and some will pearhaps be completly diferente like water entry...

I believe nx is not able to do the job parametricly
If any one have the same kind of xp please advise.


IMPORTANT

I also like to refer that mirror assembly command still completly sucks, i mean if you try to mirror a component with a block and a screw for an example, you´ll be lucky if nx create the right type of mirrored, I might be crazy but souldn´t a "mirror something" sould have only one solution?????????
the mirror assembly turn completly out of hand if you add another screw to the asembly to be mirrored.

UG guys sould really take a look into this because i can´t control a simple mirrored assembly with a block and 2 screws in it.

please : try it so you understand what i´m sying. thanks

RE: MIRROR ISSUE

Have you tried Instance Mirror Body??
This is parametric and if you mirror along the centerline of the part you can unite the 2 after and get 1 solid.

hi,
mirror body work perfecly, it´s when you try to mirror assembly and subassembly that nx doesn´t work at all.

thanks

RE: MIRROR ISSUE

I think your understanding of what it does may be the subject of some unrealistic expectations as you describe how it works for you. With fasteners and other generally symmetrical components it usually does a great job of getting them in the right position. the mirror assembly command in my understanding of it is a one time wizard kind of thing not a feature that you can expect to parametrically update. It will create a separate component in the mirrored location if a symmetrical solution cannot be found. That it attempts this as all is quite impressive and you do have some control during the process as to whether you assign mirror geometry rather than just attempt to reposition. When you do this you get linked mirrored bodies and a new mirrored component. With the linked mirrors in you case you should look at deleting the faces that you don't want or adding features to either side after the linked mirror that will reflect the gating differences in your tool etc...

I'm sure it works quite well and that you were just missing some steps.

RE: MIRROR ISSUE

You might also check to make sure that your assembly is not using faceted bodies, which act a little different and don't update as well as the true component.  And also remember that any component instance in UG creates an "automatic" mating condition, that may need to be removed in order to make updates if geometry changes drastically.  Sometimes, the fastest way to update a bunch of instanced components is to delete, then recreate the instance.  But I have a sneaking suspicion that you are using some sort of geometry such as a face or an edge for your mirror centerline.  You should always use a datum instead.  Much easier to control that way....
