I lost many time for a simple holes!!!!!!, I'm sorry but I don't understand your explanations, I'M NOVICE..............!, and I worked during 2 months on my project, and it will be finished when I will solve this F....hole problem, so I'm very nervous with that now............!

1) Create a polygon of the proper shape and size you want your circular port. You'll use this as a visual reference.
How make a circular polygon ?, is it possible or not?, incredible if not!

2) Select the surface in the hull where you want to make the hole.
I select my surface wall or surface polygon?

3) Surface Mode.... Surface \ Make Hole. This will create a hole of the same shape as the surface itself.
I apply that on my wall or on the polygon?, if I apply on the wall I got immediatly
a square hole????, if I apply on the polygon I obtain a hole with the same
shape, BUT MORE LITTLE...........!!!!?????

4) Now, in applicable Ortho view, orient your reference porthole shape in front of the hole you created with the Make Hole function.
WHAT???, how make that?, the hole I created IS IN my reference porthole shape?

5) Going to Vertex Mode, select Pairs of vertices and if needed, Vertex / Add Vertice
I DON'T FIND Paires of vertices or Vertex / Add vertice in Vertex Mode?????

I'm very DESPIT with AC3D and his MINUS TUTORIAL!!!!
MANY THANKS FOR TRIED TO HELP ME!!!!!!!!!!
