Shell Command Behaving Weirdly

[sahil.parashar]

Cant seem to apply shell command on the whole body

Yep.

Don't know why, but it will do it before the Loft.

Might help....

Thank you sir

@sahil.parashar You should not have accepted @davebYYPCU answer as a solution. He did not explain the problem and also skipped of the other flaws in your design. Are you interested in learning this properly ?

@sahil.parashar 

Fillet features are far less expensive to manufacture than Loft features.

See Attached.

Not able to explain - weird and unexpected.  Same result as op.

You may know the Why, care to share?

Found an easy fix. (Didn’t even break the Loft)

Before I answer, I  have to say that the @TheCADWhisperer is really a better solution to this geometry problem. I don't really see a need to do a loft, BUT ..

If you have to have a loft and with G2 curvature continuity (but not only then), then you need to always look at least at the curvature map and zebra stripes. Both look horrible in this case, because while the transition between the two pieces is G2, the fillets are only G1. 

If you set the fillets to G2 then it gets a little better, but only marginally:

The real improvement comes when you enable the "keep tangent edges" option in the loft dialogue:

Still, the fillets aren't consistent.

Filleting afterwards is almost always a better solution than lofting filleted geometry:

Then, the 1st sketch isn't fully defined and there is a position capture feature in the timeline that shouldn't be there ...
