I think we need another line of help info positioning the ramp section.
Place ramp section 77823 at y=-14.5 and z=-50 and then rotate 60 degrees around the ramp center point

* Guess this is another rounding issue:

5 24 8.2101 -58.4225 70.0136 60 -24 70 14.6 -59.6 70 -8.2101 -58.4225 70.0136
5 24 -8.2101 -58.4225 70.0136 -60 -24 70 -14.6 -59.6 70 60 -24 70

with z=70

* I followed the instruction in the HELP and got this:

1 16 0 -14.5 -50 1 0 0 0 .5 -.86603 0 .86603 .5 77823.dat

which obviously is wrong.

* Gap:

2 25 2.2962 -15.791143233 -95.5434 -2.2962 -15.791143233 -95.5434
2 25 -2.2962 -15.791143233 -95.5434 0 -15.6854 -96

* T-junk

Can you show me a REAL problem? I no longer use non trivial rects (just to please you 😁), but I'm tired of "fixing" non-issues on older parts...

* You have to inline a part to the bare bone to find an edge overlaying a rect
* You are surely on the save side with a 5-digit rect, but there is no guarantee a second author picking up your part doesn't round to 3 (open gaps)
* You will find rect1 on the PT with 5 digits to save 1 line of code
* You try to get some figures of a vertex but you can't, 'cos this damn thing never fits.
1 16 71.25 -39.6 8.4 8.75 0 0 0 -1 0 0 0 -1.3 rect.dat (in your s01)
* You select a quad with the aim to move it out to check some things but it doesn't and you wonder why? It's then that you find out that it's actually a rect.
* Probably in 99% of the case your rect is the product of rectifier. Apparently it's not something you think of during the design process, also because the benefit of saving time is not there. No benefit from prim substitution. Why on earth should I use it in the first place?

I fully agree on new parts. But this one is done like this, I won't spent hours so called fixing it with 0 benefit.

* Where is the problem? You had to fix the part anyway. How much does it cost to inline some rects?

Inlining rects without checking each and every vertex is useless.

If you can't see it it's no problem!!!

* I'm the last one telling you how to write your parts. Feel free to use as many rects you like, if you think they are fine and help your design ... I feel free not certifying parts containing rects. (I'm sure someone will).
