in my model i have awful triangulation that is making my bevel not working at all. ( i just want a bevel to this front face right here , the downside L)
normally what i do is just dissolving the unwanted edge and voila i have a polygon an my bevel work again
this time it doesnt work and i cant get rid of this , i dont understand why , decimating with the planar option at 5 degree also dont work.
