Hello everybody,

I'm having troubles when using 'sketch driven component pattern'.

I need to pattern an insert to be fitted in the three hex holes on a sheet-metal part.

I don't like using 'sketch driven component pattern' in assemblies. I rather use 'Pattern driven component pattern', but in this case the three holes have not been created with a pattern and I cannot change it, as it's a common part created and used by others, too.

So, I created the sketch in the assembly 

then I mated the first insert

then I patterned it

Everything looks fine, but it's not!!

I should have the original part and two additional components in the pattern but, looking at the tree, I get the original part and three additional components in the pattern, that counts four in total.

What's wrong?

I solved it with a workaround by suppressing the first instance in the pattern, but I think SW shoundn't work like that.

I'm on SW2018 SP5

Do you get the same?
