Sectiontools

Sometimes when using section tools i get a section from right to left and sometimes the left to right.

I can’t work out why,I am sure i am being stupid,Can someone explain why this is happening?

Thanks

Ahhhhh,I think just worked it out.
It depends on the view you are sectioning,(Front/Back)

Sec5 was done vith back view and sec 6 from the front
