Optimisation. Take into account the skirt margin to arrange multiple parts

[rongith]

Version

2.2.0-alpha2

Operating system type + version

Windows 10 x64

3D printer brand / version + firmware version (if known)

Prusa MK3S

Behavior

I can't arrange more than 183 parts in that case:

That is because the arrange feature doesn't take into account the skirt. The parts fit on the plate but not the skirt.

Project File (.3MF) where problem occurs

I have the same problem in 2.4.0 beta 1. Arrange can't be used to fill more than appr. 50-60% of the build plate area of our IDEX printer.

I kept hitting this situation while printing out batches of parts, so I wrote #7653 for my local build. It has its own tradeoff (as described in the PR), but so far I find it much more useful than the current version.

Would it be possible to specify a way to limit the auto-arrange arrange area, in the same dialog box where you specify the space between objects? That would, I could say, "auto-arrange these parts into this rectangle" and the auto-arrange would use that rectangle only instead of the whole print area.

Suggestion -

1. Skirt distance + (loops * extrusion width) applied as mask to perimeter of build area for Arrange calculation

• Assume entire build area in use for "minimum extrusion length" calculating loop count, since it'll be guaranteed this size or smaller.

2. Build margin parameter for Arrange tool, allowing a generic user-defined margin to be applied to auto arrange calculation

Either seems easy enough to implement, both fix multiple potential issues.

Arrange function accounts for brim and skirt since 2.6.0-alpha6. Closing.
