Week 8 - Challenge 4 - Bumper

Crested class B surface and Class C surface.

extrapolated the class B larger than class A to intersect with class AC.

but cant able to trim. both Class AC and Class B.

sweep for class C is also not able to do more than 1mm, but we needed atlest 4mm for intersection and trimming.

There is no mentoring section slots free to clear my doubts. so reply me with a solution for it.
