[Liger0]

Application version
4.7

Platform
Windows 10 x64

Printer
Cr10s

Reproduction steps

1. Place multiple models on the build plate
2. Automatically place the models

Actual results
Some models are placed on the bed margin, even though the margins are not a valid printable area and there is space to place them all

Expected results
The unprintable area should be considered.

Yeah, we knew about this and improving the arrange functionality is a high-priority task for the next release. It's supposed to be a big feature.

In my case I put a small model, so it gets placed in the center, then I do multiply and I set One at a time as _Print Sequence_ and then I arrange all models.

The result is that the first model is still in the center and all the other are pleced in line outside of the bed.

If I arrange before change the _Print Sequence_ options the models are placed too close so then it's not able to print with One at a Time

The case for one-at-a-time mode is also reported here: https://github.com/Ultimaker/Cura/issues/8329
It's a bit of a separate issue. The collision areas for objects are wrong in one-at-a-time mode, as can be seen if the "ensure models are kept apart" preference is enabled.
