Another possible technique is to model a sort of "scallop" surface and then use a boolean to cut that material away from the base solid, and then you follow that with a fillet to round off the edges.

That looks something like this - some sort of profile and path curve similar to this:



A surface can then be constructed from those using sweep - select the bottom one first to be the profile curve, then run Construct > Sweep and pick the other one as the rail path. That builds a surface like so:



This surface relates to the main body in this way, note how it is extends all the way through the body so that it will be able to cut it:



Use Transform > Array > Circular to replicate it around into a circular pattern:



Now select the main body and run Construct > Boolean > Difference, and pick those scallop surfaces as the cutting objects. That will slice the main body with those surfaces and result in several pieces, select these pieces:



And then delete those objects, leaving just the big piece behind:



Then use Construct > Fillet to round off those edges:




I hope this gives you the general idea - you can alter the shape quite a bit by adjusting the curves that were used for constructing the scallop, to make the scallop narrower or longer or angle it differently or whatever. Also you may want to slice out another piece from the center core, maybe use a revolve on a profile curve to make a sort of dome to boolean away for that.

But anyway, you can use cutting objects in this fashion to slice away chunks and that then forms the feet out of the remaining areas.

Here is a bottle I did a while back. Uses the same method that Michael suggests. Remember: there are no rules. All that matters is how it looks.

Took me a while, but this method of defining rough shapes and then filleting, finally clicked in my head last week when I was modelling a cell phone. I started out trying to lay down some contour curves, but it quickly got difficult to manage. So I started over and just roughly blocked out some shapes and then applied a fillet. It's a much faster workflow and it made me look smarter than I actually am. :-]

Hi TwinSnakes, that's great that method is clicking!

It takes a while to get used to it - basically when you look at a shape and there is some mixture of broad shapes and then some more tightly bent areas try to temporarily ignore the tightly bent transition areas since those are indicative of fillets.

The other kind of thing is not getting too focused on building surfaces that directly hug to some irregular outline - usually you want to build an extended surface and then cut it rather than trying to construct the surface initially to such an outline. That kind of thing with visualizing extended areas of the model earlier on in the process can sometimes take a while to get the hang of as well.

- Michael
