I just recently downloaded the new SketchUp 2017 and I’m not sure where some of my options went. I previously used the Layers Panel quite frequently and usually accessed it through the Window drop down, but now that easily accessible panel seems to only be offered as a tray. I was wondering if there is still a way to use the panel rather than the somewhat cumbersome tray format.
I understand that there is not a big difference between the two layers panels in the pictures, but any help in learning where all of the previous Window options are now being held/whether or not they are even available any longer would be greatly appreciated.
Which operating system are you using? Your screen shots show both Mac and PC and your profile indicates Mac. On Mac the windows are still as in your first screen shot and float over the drawing space. On the PC for the last several versions, they are normally found in the Default Tray which is normally positioned on the far right side of the screen but outside the modeling space. This means they don’t have to float over the model. You can make trays for individual windows if you wish and have them positioned over the model space as in your second image if you want.
As for where they went in the Window menu, you can choose which ones are shown in the default tray and if you want to make your own trays, click on Manage Trays or New Tray and select the windows you wish to use there.
The windows in the tray do not cover the model space. You can keep those windows you’re not using rolled up which keeps them ready for use without having to go to the Window menu every time you want them.
