Hi,
What is the best practice to draw this jar in attachment.
I've tested boolean, gordon or tend but the result isn't good enough, because i can't fillet the edges
Thanks in advance..

Bonsoir Finemà et Pilou

my idea:






Loft "rigid" option



Draw a circle and extrude both ways without cap ends





Bool diff



Fillet these first







Select the solid and fillet

Thanks a lot Mauro.

Can I use the same practice with a conical model like the Bonne Maman jar ?

for the conical form, i've opened my 3dm file in Rhino and use a transform tool (taper), save it and reopen it in MoI.
thanks for your help

I'm happy to talk about modeling techniques and spend my spare time for it :)
This is MOI:a modeler first of all,not a script or math formulas container ;)

Jar tapered 6°



Rail revolve:yellow curves, profile and 8-sides as rail




Draw a polyline (yellow) always extended to avoid problems when boolean difference




Fillet the polyline to 30 mm




Extrude in both ways,once again extended as said above



Rail revolve:this will be the Jar




Turn on previous surface




Polar array:8 copies




Bool difference:subtract 8 copies and deleting



Select solid and hit fillet=5mm





Pushing fillet to 40mm




model attached,open the browser to get construction lines

You can make it in less steps.

Extrude between upper and lower circles and proceed as above.

Sure you can do it in less steps,i just expanded for better understanding
Now it depends what shape you want and if you can fillet the solid
There are little differences between two workflows



Can you fillet it ?
If you want different fillet radius between blue edges and the rest you can fillet first using red line lenght as radius,not more





I follow your workflow without fillet the surface to subtract



when i do the final fillet it doesn't work (radius 1mm)



Fillet engine must have good conditions to work(as Michael explained many times),little variations can make the difference
Probably this is happened to Finema

Hi
I meant loft not extrude but that may not make any difference. I did fillet it at the end and it worked ok. I'm not being competitive just pleased to have made it so simply. Of course I might have been lucky as I often find when I try and make an exact model filleting can be tricky.

Thank you Keith for your suggestions :)
I used Rail Revolve instead of Loft to get an exact revolved surface
No competition-just share !
