I finally moved from Pro 2018 to 2019 “classic” license. I have well over 100 layers in my models and have a numbering convention (x.xxx_layer name) for naming layers so that they sort according to the numbers at the start of the layer name. I find that they’re not sorting properly in 2019. For instance, I have a layer that begins with 5.39 listed above 5.13. I’ve quit / reopened SU, reset Workspace and hit the “Name” column header to switch the sorting. So far, nothing has worked.
I just added a couple of layers to my currently opened file and named them 5.13xxxx and 5.39xxxx. They automatically went into the right order. Is it possible you’ve inadvertently sorted by color?
No, I sorted by “Name”, but subsequently discovered that the sorting order gets a little screwed up if I don’t use the same number of digits after the decimal point. I started off numbering them “x.xx_layer name” and then discovered I actually needed to delineate a little finer and went to “x.xxx_layer name”, which is when the issue came up - in 2019, it wasn’t an issue in 2018. I was able to add a “0” at the end of those layers named with just 2 digits after the decimal and it all went back to sorting as expected.
