Mursten

[Peter Blomberg]

then why do we have 7 parts: 700a/b and u8010 and its variants b/c/d/e?
(as stated above, I think there may be some doubles)
Does anyone have the ones with 2 crosses and the one with the rounded/square supports?
because of the bottom stud row of some, there are differences in connecting.

This issue isn't limited to Mursten. Some contributors happily create part variants with even the smallest of differences. Sometimes visual accuracy may take precedence over part functionality. As a community-driven project, this is just something we need to live with. However, LDraw could benefit from an ontology that clearly distinguishes base parts and part variants.
