Redefinition failed???

bk shared this problem 14 years ago

I'm trying to implement a simple macro to test whether a point is inside the triangle by using a winding number.

However, when I try to define show text "Point is outside" on condition "alpha=0 deg", I get "Redefinition failed" message and all my objects are deleted!

OK, I should input "alpha == 0 deg" instead of "alpha=0 deg"...

But still, why were all my objects deleted?
