Arrange in Layout not send SU model to the back

I’ve imported three SU models to my worksheet. One of the SU models will accept annotations atop. The other two will not. Trying to ‘arrange’ them to the back does not work. My annotations always disappear behind them.

Check which layer is active and which layer contains the SketchUp viewports. Unlike SketchUp, layer order in LayOut is very important. Entities on layers lower in the list will be under entities higher in the list.

Send to Front/Back only works for entities on the same layer.

It worked. Thanks.
