difficulty to get a clean geometry

[pascalchap]

Hello,

I am trying to build a lamp model, and I am facing difficulties to get a clean geometry.

I tried different way to build my model and read many useful information in this forum, but I always end with a weird behavior.

here what I have done so far:








It is not the final model, but before creating holes and bumps of various shapes on the face I would like to get a clean model.

Please, can someone tell me what is occurring on my model and why?
