I have rebuilt the main body and joined the ridge part as you suggested. Its much better with your instructions thanks. Remaking the body ontop of the old one worked out pretty easy aswell, just snapping circles to circles and making sure I had the right bits selected before boolean diff subtracting and merging pieces.






The flint holder was going well. I made the profile curves as suggested, vertical lines and tangent arcs. I extruded the curves and then boolean diff subtracted out a cube from the middle, but couldn't get the fillets to work on the inside edges. I was suspicious of the little straight part at the bottom so removed that and tried the above steps again and the fillets worked fine. Sweetness.







Thanks for your help sorting these bits out, its a fun and refreshing change using Moi to my regular poly modelling toolsets.

Hi Wheel, that is great progress.

You've gotten the hang of NURBS modeling very quickly, even to the point of knowing which things the filleter doesn't like! :)

Yeah co-planar bits split up into multiple small pieces tends to bother it right now.

You've already fixed it, but just a note on the quickest way to do so - you can delete those 2 co-planar pieces, then select the whole object that now has a hole in it, and use Construct/Planar to fill in the larger planar hole. There is stuff in the booleans that tries to do this automatically but there are some circumstances where it doesn't work yet.

Construct/Planar can be used to either create a trimmed plane surface from a set of planar curves, or it will also fill in planar open holes on surface/solid type models.

If it doesn't fill, then it means something is not planar there - that was actually the first clue to me that something was slightly off on your original shape.

You're welcome, and I'm glad you are having fun using MoI!

It's nice to have the combination of both of these different kinds of toolsets available to you, depending on the type of model you are currently building.
