Fix Import STEP Assembly as Part - Components in Wrong Position

[lhoogeveen]

It's common to import supplier CAD assemblies as a part to only manage one object in Creo/Windchill. In Creo 4 M090 and Creo 6.0.2.0, the default for importing STEP assemblies as a part results in the components coming in the wrong position. I opened a case with PTC... apparently there's a hidden Creo config setting intf3d_in_as_part yes to fix this as discussed in CS10021 but this setting also changes the default selection to import as part at the same time. PTC Support suggested creating a product idea.

As Creo 7 now supports multiple bodies for parts, it would be nice if we could easily import STEP assembly components as a part 'body' AND get the components in the correct position (haven't tried Creo 7 yet since it came out yesterday).

Please fix:

• With intf3d_in_as_part no (the default), selecting import STEP assembly as part should import the parts in the correct assembly position.
• intf3d_in_as_part should only change which box is checked by default and should NOT be a hidden setting.

I agree I've used this option for years and it is so useful when you want to store an assembly model as a single part.  Supplier parts especially.  I really feel that this should be standard, but I cannot remember if there was a reason that this option is not default behavior.  In any case I would prefer it be in the import menu and not a hidden configuration option.

There are certain conditions where intf3d_in_as_part yes does not work correctly.  It was never finalized and made 'production ready', so the config option to enable it has remained hidden (use at your own risk).  There is work going on to make importing an assembly to a multi-body part fully supported and automatic.

One example where intf3d_in_as_part does not work correctly is when the assembly being imported has components with mixed units.  When the assembly is imported into an inch part, any metric components will be scaled up having their mm values treated as inch values, effectively making the models huge.
