Why can I not select faces?

In top mode why can I not select individual faces in the ribbed area of the handgun? Thanks

Because they are covered with long faces

I am actually able to select them, anyway you have some longitudinal faces that cover the traversal ones and are not linked with them, that is wrong and makes all that ribbed area to not appear at all.

First off you should remove N-gons, then delete those faces and to bridge edges so to make proper faces between the ribs.


Thank you JA12 and Sourvinos. I will try it in the morning.
