System Information
Version: 3.3.2 Release Candidate, branch: master, commit date: 2022-10-17 14:20, hash: c98268d3f5, type: release
Build date: 2022-10-18, 00:42:54
Platform: 'Windows-10-10.0.22621-SP0'

Renderer: 'NVIDIA GeForce RTX 3090/PCIe/SSE2'
Vendor: 'NVIDIA Corporation'
Version: '4.5.0 NVIDIA 516.59'

Short description of error
Line Art usage mode "Force Intersection" doesn't work like expected. See my screenshot and attached file for tests.

Objects or collections that are set to "Force Intersection" should always produce intersections, even if other rules defines something else.
Line Art usage set to "Force Intersection" should work like a global line art override.

Exact steps for others to reproduce the error

Try to set the Line Art usage of object "Cube1" to Force Intersection mode.
Try to set the Line Art usage settings to "Force Intersection" to the Collection called "Forced Intersections".

Both settings produce no results, means: Cube1 intersections with other objects aren't visible.

Looks like an issue... Let me check

After some discussion we found out that it's not quite aligned with how line art works, because object/collection intersection option can't actually override modifier option (because the modifier only filters the result). We might be able to leave it for a while and see if we can come up with a simpler logic pattern for this kind of use cases.

@ChengduLittleA: Exactly.

You can set this to archived. Thank you.

Changed status from 'Needs Triage' to: 'Needs Developer To Reproduce'

@ChengduLittleA , since the current behavior is expected , do you want to keep this report open as a DESIGN or a TODO? or you prefer to archive it?

Hi! Sorry for the delay! I think this can be left as a DESIGN. :D
