Is it just me, or does Pro E / Creo Sheet metal leave a bit to be desired? I mean, there have been times when I’ve need to turn a flange into a flat, and split a chained flange into opposite but equal flats. I’ve been forced to part a part as a solid, then convert it to get nice, mitered corners because I don’t have nice 90° corners.
Recently, I’ve dropped a few notched in the bosses’ eyes because of a quirk with Creo. All our dwgs are the folded / formed part, with a flat pattern as the last sheet. Somehow, the included flat pattern on this particular part got disconnected from the formed part. So the part updated, but the flat remained unchanged. Something along the lines that I opened the flat pattern, saved it, and since doing so, Creo ignored its family table link, giving preference to the flat pattern file now available in the working directory. One of my coworkers was trying to explain it to me, but I only caught on to bit of what he said, as I’m tryignto hide my shame of a glaring mistake, and that the supplier caught it. (It was out by about .2”). Something along the lines that I opened the flat pattern, saved it, then opened the dwg, and the flat overwrote itself when I saved the dwg.. So, now, I / we are expected to manually verify all our bends to ensure the flat is as we intend. I now trust Creo even less than before.
I’m still new with Creo / Pro e, just under 2 years with it. Still learning, still going thru all the courses available / that pertain to me thru the PTC univ. I’m still discovering things about the program, scratching my head wondering how they thought things out.
I have a similar irk when I’ve copied a sheet metal part to create a new part. When I open the new drawing linked to the part, the dwg won’t open because it’s still calling up the old flat pattern. Why won’t the flat pattern follow the renaming of the part to the new name? SO, you have to open the new part & dwg, open the old part & dwg, delete the old part (flat pattern) from the new dwg, then re-insert the new flat pattern.. Oh, and you first have to open the new part, clear out the family table, redo the flat pattern & instance & resave it all.. And there is a bunch of regens & open & closing of the files with the odd memory cleaning in between.
I find it odd, that I have a flat pattern, supressed, and save the model. I then get a message aftger saving, saying that he flat isn’t updated. If I update the flat and save, I get the same message, but that the formed model isn’t updated.. A conundrum.. I usually update both, regen both, then save the formed part & ignore the message..
Sorry for the rant, but I'm not in a good mood after today’s fiasco. Can anyone offer up some tips and/or tricks to help a newbie along?
