I have a question about selection. I want to scale the entire model. First, I went to Edit to Select All. Then, Insert->Feature->Scale. I keyed in the scaling factor but when I clicked the green check mark at the top right of the screen to execute the command, SolidWorks asked "Please select body to be scaled" even all the parts of the model are highlighted. I clicked the top of the tree or used the mouse to highlight all the components of the three but it does not work.
