Something is bothering me a lot about stroke widths. If you have to shapes with stroke width of 3 for example and create a compound object either with or without holding ALT to keep it live, the compound object will have what appears to be a random stroke width. This number is different in Designer and Photo,
In the attached video you can see the issue. As an aside its also really annoying that you cannot change the width on multiple selections - really annoying. The only way I have found is to group them first.
I would expect in the case of multiple objects having the same width, the compound object would inherit exactly the same stroke width.
In the case of the multiple objects having different widths, I would accept the compound object inhering the largest of the widths. I just don't understand it changing to what appears to be a random number.
