Nothing more simple :)

a Copy = Ctrl + C / Crtl + V
You work principally in Session A, Session B is your save "SpaceSphip" not filleted! :)
you can have any number of sessions in the same time

Minute 1
Session A : Object O very complex
Session B : Object O copied (from Session A) without Fillet

Minute 2
Session A : Object O Filleted
Session B : Object O - nothing to do

Minute 10 You don't want the Object O with Fillets for any reason so...
Session A : kill the Object O
Session B : Copy Object O (original) for the Session A

Minute 11
Session A : Object O not Filleted (because copied from session B )
Session B : Object O copied without Fillet - nothing to do - or can be receive a new object O modified without fillet you are not oblige to kill the first one...that becomes your data base of unfilleted objects!
etc...
All that avoid to calculate the unfillet (in general impossible in few time) an object at any time of it's conception!
It's very rustic but very efficient!

Hmmm .. With difficulty, but - it seems - I understood.

We call such a pipeline "dancing with a tambourine".
All this is very nice, but I can't understand why, why should I do a lot of these useless actions (and still keep all this in my head), if I can - stupidly - open an object in spaceclay, delete a fillet (if it was created by mistake) - and continue to work calmly without wasting time on all these body movements (which you so kindly and diligently described)

And I'm not talking about the pipeline, I'm asking about the meaning !!

In theory, I can climb to my apartment on the 5th floor using ropes and climbing pitons.
But I prefer the elevator!

here i don't kill the fillet object by caution in case of ...as you can see it's some speedy! :)
Very more speedy than your Spaceclaim video! ,)



Seems you don't understand that a function of Unfillet a complex object is not yet easily existing..in Moi or inside some other progs! :)

So we can find some tricky replacements! ;)

>>Seems you don't understand that a function of Unfillet a complex object is not yet easily existing..in Moi or inside some other progs! :)

I understand it perfectly! That is why I provided a solution to this problem using a third-party program.
That's all.

So you have now 2 solutions !
But SpaceClaim is not a low cost prog...

Yes you are right.
But there is also Plasticity, it is completely free and can also remove fillets.
Not everything is not as cool as SC, but still, still ...

Beta of Plasticity is free yes but final product will more than the 25$ announced because
Kernel Parasolid is used against Kernel C3D! So price will be more than very low cost! ;)
I doubt there will 2 versions Parasolid / C3D but who knows! :)

Wait - and see!

Post your example file. Your spaceclaim video at 1.21 created malformed geometry. Luckily they wanted the entire feature set removed or else, oops!

“Removing holes” is in regards to untrimming trimmed surfaces, which is what spaceclaim is doing there and why it was brought up when you asked about removing fillets. It is the same thing. Not “different”.
