Hi all,

Basically I'm trying to mirror the two extrude cuts about the right plane (See below), however this can't be completed due to a geometric condition. I can't see why as the part is symmetric.

The cut consists of two parts, the first which was partly successful, and the second which cannot be carried out:

I'm sure there must be a simple solution to this, if someone can make this part symmetrical so that all interior channels can be accessed from the outside I would much appreciate it.

Part is attached.

Cheers
