HI, I have experiencing difficulties in SW2019 when trying to detect interference. Attached is an assembly containing two parts. part 2: a solid, part 1: a bigger solid with part 2 subtracted through body combination operation. when doing interference detection I was told that part 1 and part 2 has an interfered volume of part 2, which can't be correct as part 2 has been subtracted from part 1.
I am using SW2019 SP5. I don't know if this has been fixed in later versions like 2020? Thanks.
The bug is still there in 2020 SP2. It was first reported in July 2019.
