Well this is how I would do it blender.

1st: Creat a cube and squish it down fairly thin.

Now extrude the edge up and keep extruding and shaping until you get the desired result.

Squish the cube a bunch or a little depending how round or flat you want it.

Hi Misty! Personally, I use to do that with the "Polyline's tool" in the vertex room, but here is a good tuto with the extrusion method: https://www.youtube.com/watch?v=dr3ynKuPx50 I like also the Mark Bremmer's method in the Spline modeler: https://www.youtube.com/watch?v=SXoRUOBNQ08

thanks all.

anyway, this is what i ended up doing, inserted oval(circle) to use as a guide, inserted a grid on top of it. moved the outer verts of the grid to line up with the oval verts.

whole bottle still ended up with high poly count, like 800

Here is another method as per Vyusur which might perform better under smoothing. Rather than start with a square, you can also start with an oval or a cylinder. Here I start with a cylinder with 12 points on loop. Extrude in once to brace the edge loop. Then use Tessalate and join vertexes to center. This yield triangles. No problem. Select two triangles at a time and dissolve (backspace). Now the end of the cylinder is made of quads but the edge loop is braced by an circle. Repeat for other end if closing bottle, or delete other end if bottle is open. Select edge loops of cylinder and shape as desired for bottle length and width.

Hmm, sorry for the repeats. Here is the screencap I meant to include.a04 select two triangles an use backspace to dissolve.JPG

and here is the bottom edge braced by having the quad dissolves near same level as desired bottom edge a10 see edge again.JPG

Here is the thickened bottle even with smoothing applied. Bottom loops are braced with a loop, then points go to center.b01 bottom holds shape even with smoothing.JPG

thanks diomede

your method lowers the polycount 🐼

i'm finding when i detach polys, haz to deselect and reselect the polys to move
