"If the part has studs, the origin shall be the bottom of the topmost stud group."
"If a part doesn't have studs, the origin shall be the bottom of the part."
Despite the docs being very clear about the height of the origin, there are a number of exceptions.
Double curved top:
Official part 31213b has the origin at the top of the part. Sadly, the part was recently edited to correct for orientation. Since the origin height is a multiple of 48, moving the origin to 0 yields no benefit.
Official part 3664 has the origin at 24 LDU. This part should be rotated. The height can be corrected at the same time.
Bases of some kind:
Official part 13358 has the origin at 24 LDU. This was considered tolerable due to the snapping hole.
Official part 92005 has the origin at 24 LDU. The part has a snapping stud.
Official part 92011 has the origin at 48 LDU. The part has a snapping stud.
Parts 13358, 92005, and 92011 have the origin at a height which is a multiple of 24 (Duplo plate height), thus yielding no benefit from moving the origin to 0.
Official part 6405 has the origin at 16 LDU where the base is. This part should be rotated. The height can be corrected at the same time. ...or keep as is (see argument below)
Other:
Official part 4913 has the origin at 16 LDU where the base is.
Official part 4375 has the origin at 16 LDU where the base is.
Official part 4894 has the origin at 16 LDU where the base is.
Parts 4913, 4375, and 4894 have a base at 16 LDU, which could be used as an argument for not needing correction. Placing these parts would always be challenging (not a multiple of 24).
Official part 15327 (shower) has the origin at 16 LDU.
Official part 51708 (flagpole) has the origin at 16 LDU.
Official part 31925 (flag) has the origin at the bottom despite having a stud. This part is on the tracker for another reason.
There are four parts on the tracker with a hold. They have their origin at the bottom, thus following the docs.
I suggest we edit 3664 (needs to be edited anyway), keep 6405, 4913, 4375, and 4894 as they are until they are edited for another reason, and change the origin height of 15327 and 51708 as b replacement versions, and update the origin height of 31925 to the bottom of the top stud. Is this ok?
