Sorry for the confusion Robert,

If I can simplifies the procedure (and I welcome any 2nd opinions):

Your pics 1 and 2 shows how the first step is to make the openings in the outer surface.
In the Pics 3 and 4, the yellow surface simply represents a temporary extrusion made from the shape representing the inside perimeter of the handle.
The extrusion starts at exactly the middle point of inside of the bottle. Pics 4 and 5 shows a Blend (in the Construct menu) which has been made between the outside opening of the bottle and the edge of the temporary extrusion surface.
After the Blend surface is created the extrusion surface can be deleted. A second Blend can now be made between the edge of the first blend (in the middle) and the opposite outside opening of the bottle.
The purpose of the extrusion from the middle was to ensure that the inside surface of the handle occupies and exact position.

This was but one way to go about creating such an organically-shaped opening.

Hi Robert,

> In pic6 I turned of grid. How do you turn off the x,y displayed?

That's under Options > Grid > "Show grid axes".

Michael, would be nice to have "Show grid axes" in the main window since you already have "Show Grid".

Mike, excellent tutorials you have. Trying to explain your models is not an easy task. You usually need two or three checks from other viewers to catch missing info.
I will suggest, make statements and ask questions in missing info that might help explain some of your detail modeling.

1. You say you can use trim or project. in pic1 why do you have two curves in making the handle cutout. one larger than the other? Being new to Moi I found out that if using trim in this bottle, you have to trim each side separately . If using project you would have to project from center to each side.

2. In pic2 you show copy? was this suppose to be project?

3. In pic3 you extrude from the small curve in the center going out to the back side.

4. In pic4 you blend from the larger curve in the fore ground to the center smaller curve.

5. In pic5 the view is the other side of the bottle being blended from the center small curve to the larger outside curve.

These are my comments, hope you understand them. I will continue with to finish the bottle and will ask questions if I get stuck again.

Thank Mike.
