Copy geometry help

[nofalloff]

Trying my hand at top down design I've created an assembly. The
first part is a skeleton part with an imported DXF file of the outline geometry
of the parts I'm trying to make. the way I understand the process (please
correct me if I'm wrong) is that I create new parts in the assembly mode using
the default coordinate system, activate that part, highlight relevant geometry
on the skeleton, then copy (control C and past (control V) that into the
activated part. Is this correct? When I try this I'm only allowed to pick one
entity or loop at a time. I though I should be able to copy multiple features
in one shot. What am I doing wrong?

nofalloff,


The idea is to create a publish geom in which you gather all your references in the skeleton. Then you copy this via copy geom to your part, and take it from there. Prevents circular refs when you start moving things arouind, and the pub geom can be expanded to include more refs later if needed.

It takes some practice.

I put hole locations in my skeleton as a circular datum curve for example so my upper housing Boss and lower housing boss will move when I move the hole location in the skeleton.

Not that when you do the top down design try to



1. Relate the part only to the skeleton model

2. If at all u r relating to some other parts in the later stages of the
assembly then try to keep the reference part up in the model tree



Other wise it will turn out to be a hell

So how do I copy multiple datum features from the skeleton part into another part in the assembly? Are they then associative or can that be broken so that the part can stand alone?

Don't use copy/paste.

Activate the target part and select insert -> data sharing -> copy geometry. You can then add in any number of curves, datum features, surface, etc. and they will be copied from the source and remain associative. You can turn off the associativity in the copy geometry dialog.

Better yer, open your source part (skeleton) and create a publish geometry. It's under insert - shared data -> Publish geometry. It's like a box you put geometry to share with the target part. The dialog is nearly identical to the copy geometry. Once you've defined it, you go back to the assembly and create the copy geometry as described above, but instead of picking geometry items you use the publish geometry button on the dashboard (or in the dialog, if you're pre-WF3). Pro|e then 'looks in the box' and copies whatever is in there to the target part. The nice thing about this is later, if you need to copy more things, you simple re-define the publish in the skeleton and regenerate the target model. Upon regeneration, Pro|E 'looks in the box' again and find that new stuff is there and adds it too. Very handy.

Doug,
Thanks.

Doug,



wonderful way of exlaining thinks

I liked the way u refered publish geomatry as a Box
