Are underside reinforcements relevant?


RE: Are underside reinforcements relevant?
#3
Interesting question.

concerning mould differences, e.g. there are different moulds of 3001, where the walls got thinner and to still have cluth-power, some very small filltes have been added. those are not modeled, we kept the 4 LDU thick part. That is fine

Whenever an understud is held in place (reinforced) with a fillet, I would tend to have this modeled. As it is also part of the geometry that prohibits a bar or something else going into this place.
If such a thing is completely invisible, as it is part of an animal consisting of two distinct halfs, I would leave it up to the author, but those can be skipped IMHO, if it is not a transparent part, e.g. like the deer.

An example for a considerable mould change here is the "Duplo Roof Sloped 33  4 x  4 with  9 Bottom Tubes with Awning Overhang". This has two moulds (and design-IDs), which are for the basic Duplo build practically the same. However their underside is very different. 9 versus 5 anti-studs. So this is definately a "yes" to be modeled"

Examples where the reinfocement could be skipped are the "blates" the two plate thick "baseplates" those have usually some diagonal reinforecements 20-30 LDU wide and 1 LDU high, so basically they just make the top of the plate thicker, those are not necessary in my view. Mecabricks models them, but those are not necessary IMHO.
