the little tractor is hovering inside the yellow container.

I have a couple of template snippets that I (intend to) re-use, but my ropes are also a little non-compliant because I use old LSynth constraints instead of the "official" LDCad rope/string donors.

It would be great if someone could review the file and let me know if it is ok. If so, I will make the remaining back of the box models for this set. Thanks!

6645 - Street Sweeper B-Model (1991)





OMR compliant

What software do you use for building?
The transformation matrices should be rounded to 0, 1 or -1 if the part is placed horizontally or vertically (at least each component cannot be >1 or <-1 by any rotation).

I'm looking forward to see more alternative builds for this and other sets!!

I have started to name them alphabetically (A, B, C...), as I have noticed that seems to be how it is done on sites like backoftheboxbuilds.com , and Eurobricks. I am not sure if that is in line with the LDraw naming, though?

Though there is admittedly some gray area, like set 8448 which gives only the beginning steps for several of its alternate builds.

Ok, then for now I would propose that the lettering covers the instructions first and then continues with the lid and back of the box. So if there is a second model in the instructions, it would be "B", and then I would continue with "C" for the models on lid and the back.
I hope that is ok? We can always change it later if there is an official naming pattern.

(2022-05-18, 13:21)N. W. Perry Wrote: As far as the name for OMR purposes, the only thing to mention is that there should be a hyphen between the set name and the sub-model, like this:
6645 - Street Sweeper - B model

MPDCenter doesn't catch this, probably because it doesn't have a database of valid set names.

As for the A, B, C pattern, I think your scheme is perfectly logical, and OMR guidelines leave the sub-model name up to the author's discretion. (It does suggest that the name be descriptive of the model, but since these are all just different street sweepers…)

So the only other question, really, is whether the OMR desires to have back-of-the-box builds included, but there's certainly no harm in posting them and this is the forum to do it!
