Orientation of Duplo 11197 - Peter Blomberg - 2025-03-25
Let's discuss the orientation of (sloped) Duplo parts.
First of all, sloped Duplo parts have not been oriented as systematically as regular parts. There were some trends (reviewed here https://forums.ldraw.org/thread-28480.html). The existing official parts have several orientations where one major trend seems to be the patterning of a side surface taking precedence over 'slopeness'. This may be partly due to the LDPE editor, where -z is considered the front face of the part and the patterns have been considered the front in common use cases.
Part 11197 is mainly patterned on the side and used in conjunction with part 4198 (https://library.ldraw.org/parts/8177), which is also mainly patterned on the side and oriented in the -z direction.
Therefore, it makes sense to orient part 11197 also in the -z direction.
An alternative would be to rotate all existing sloped parts and their patterns to fit the same convention adopted for sloped regular lego.

Consider also that the new PREVIEW meta solves a lot of issues but I agree that all sloped/curved parts should share a logical orientation.
Feel free to "moveto" official part with a new orientation as you see fit. Document the reason for the new orientation in the HISTORY.

This is the preferred route. How many parts would we have to change?

13 official parts, plus 3 derivative parts, 9 subparts, and 25 patterns. Additional 9 unofficial patterns.
Part numbers: 3664, 31213, 2301, 2302, 98223, 4198, 72133, 4258, 73162, 98252, 98224, u977, 4197, 11198, 250, and 51704.
These updates/corrections could be made at the same time:
Part 31213 should be subfiled for patterns. 2302 remove invisible lines on inside, already on PT. Parts 98252, 98224, and 4197 curves should be updated to match 11169. Bottom curves of 4198 should be updated to match 11169. Some of the older parts are not using stud groups.
