A bit of help needed for part 76923 please - Peter Grass - 2026-02-26
So I am having a go at making part 76923, and have done most of it. Just a few things I have a query about.
A) To match the size of the BI original, the handle primatives of the bar needed to be scaled down by 10% in one direction is it OK to do that?
B) the support beams for the bottom tube. BI just has them clipping into the geometry of the tube which isn't great obviously. There are primatives for if the support beams are at the bottom of the tube but there don't seem to be any for if they are at the top? So is there a subpart or something I can use?
C) The origin for the part doesn't seem right so I was wondering where it should go? I mean yeah I know I need to adjust it so the mirroring will work properly but I want it in the right place.

BI has the part upside down which I of course need to fix too since its normally used for the lower jaw of dragons it probably should default to being the opposite way around IMO.
B) Just use clipping, no problem doing so, and best possible render. In this case I generally use a box3u4p prim appropriately scaled and placed, and 2 intersection lines on top.
C) A part with studs is supposed to have origin at stud base level, and keep symmetry. Here it will be on top of the axlehole. Note that orientation of all similar parts have X axis left/right, and Z axis front/back, so it should be turned 90° around Y axis.
Vertical orientation is fine as it is.

I would like you to remove the duplicated surface inside the bottom stud
1 16 10 -16 -10 0 0 1 0 10.5 0 1 0 0 axlehole.dat
1 16 10 -13.5 -10 0 0 1 0 -3.35 0 -1 0 0 stud4.dat
The top studs can't be in the subfile. Need to be at top level to avoid mirroring of the logo.
Cutting flat surface that go across the cutting plane is not good. Like these:
4 16 -10 0 -10 -10 0 6.25 -6.36 0 6.25 -6.36 0 -10
4 16 -10 0 6.25 -10 0 -10 -10 -16 -10 -10 -16 6.183
4 16 26.25 -7.18 -10 26.25 -7.18 -8.75 26.25 0 6.25 26.25 0 -10
.. and more.
