Inheritence Feature Names

[eaolsen]

Ok, here's the question ofthe day...

I am working on a casting-machining that was created by using an inheritence
feature to bring the casting model into the machining model. In the casting
model, there are datums named A, B, and C. I also need datums in the
machining model named A, B, and C to use in GD&T that will be shown on the
drawing. Pro will not allow me to name a feature in the machining model A
because there is already an A inside the inheritence feature. And yet, when
I create the GD&T items I cannot reference A, B and C inside the inheritence
feature.

Does anyone know of a way around this?

Thanks,

Erik Olsen

Instead of an inheritance feature, we use a copy-geom, (& solidify)
which copies the datums with new names, which can be renamed.

If A, B, C exist prior to creating the inheritance Pro/E will append the
names of the inheritance datums with an "_1".



As a side note, the named datums in the inheritance can not be renamed and
if they are renamed in the original source model they do not appear to
update in the target model. PTC has some work to finish up here.

I don?t want to take this off-topic, but I?ve always had success using Merge
in a temporary assembly; the parts always update fine ? but I?ve seen some
discussion lately saying that Merge should not be used nowadays and that
Inheritance should be used ? can someone tell me why?

Erik, you can use this work around:

Rename the datums in the parent model to new names like AA, BB and CC.
Regenerate the Inheritance model.
Create new datum planes in the inheritance through the 3 Datums coming
from the parent model. Make these Set Datums and set their names to A, B
and C.
Rename the datums in the parent model back to A, B and C
Regenerate the Inheritance model.

You are not allowed to rename any features inside the inheritance feature,
which was what you where trying in a very similar suggested method
described in your summary.

Regards,
Bjarne
