I thought ID would be gone by the end of October.
It's still okay.
Let me ask you a question.
I want to use the curve pattern ...
The patterned shape ...
It is not patterned as the originally drawn shape.
I think the depth is different ...
How do you make it look like a pattern?
no I don't think this is a matter of like or no like, simply over 30 years with CAD.
The IMHO key issue here was the definition of Your pattern curve.
You only selected the arc on the right but not the line where the original master cutout resides.
So Your reference point is apporx. 20mm away from the cutout and takes this offset for later placement.
This might result in an inadequate positioning of every pattern instance.
What have I done?
I have created a line (sketch) to split the plane where the master cutout is located.
Now a have a shorter line and the arc as driving curve for patterning.
And now the start/reference point is exact at the cutout center position.
Using this start point and orientation will of course result in an correct position of any pattern instance.
This - simply it is!
Nothing more and no miracle or magic
