System and Studless Techinc Standards Problem

[Philippe Hurbain]

I agree that there is a problem for a few pieces such as this one, but I don't see a good solution avoiding rewriting all Technic parts...
For this specific part I don't see such a big problem with present solution but I wouldn't object if it was modelled with a sloped top on liftarm section to have the tip 18ldu wide.

2) We model technic holes at 10LDU from the top of a brick, which is slightly too low (9LDU is closer).

According to LDD models, it's exactly 9.5 ldu.
