Question

ANSI 1982 Datums

We just upgraded to Creo 6 (from 3.0). All our legacy data was made with datum callouts per ANSI 1982. (Datum under dimension).

 

One of my users reports trouble changing a datum to show this way. The datum in question is showing per ASME 1994.

 

The properties window for datums used to have this as a radio button, but that's gone now.

 

I also know there was once a config option (.dtl I think, but maybe .pro) for how datums are displayed, but I cannot find this option now.

 

Does this option still exist? If so, what is it? How do we show datum callouts under dimensions now. (Aside from faking it with the @[-A-@] cheat.)

The change was made in Creo4.

Asme Y14.5 for defining how datums are attached was revised in the 1994 spec. That spec is now 2 releases old as there have been a 2009 and a 2018 release. Not sure when PTC will support the 2018 spec in Creo, so we have only specified the 2009 release as being our standard.

 

I do have to ask the question: Why are you just now going to Creo6 when it is no longer supported since Creo7 is out? Creo4 and now Creo7 are the 'long-term' Creo installations, released every 3 years. The intermediate releases, Creo5 and Creo6, have a 1 year support window before being replaced with the next release.

Hi Ben,

 

Yeah, I know there are multiple updates since 1982. Unfortunately I operate in an environment where changes like that are presented as seismic and squashed. Personally, I wish we would update to a newer spec.

 

So 1982 is simply no longer supported? That's going to be a pain due to our latest contract.

 

I guess my message will have to be change to newer spec or fake it.

 

When I say we just updated to Creo 6, I don't mean that like "last week we updated". We actually scheduled and completed the update to Windchill and Creo before 7 was released. When things calm down later this summer, I'll update us to Creo 7. That's something I'll do myself, unlike the Windchill updates.

What version of Windchill are you on?

 

I cannot go to Creo7 yet as we are still on Windchill 11.0 and it does not support Creo7.

I wanted to wait and go to Windchill 12, but PTC does not support that upgrade option as they only support 2 versions, so 11.1 and then 11.2, for me.

I am working on the 11.2 upgrade now, trying to figure out what is needed. Windchill upgrades are fun! lol
