I often need to select several contracts at the same time. I use the classic method with ctrl + click. I'm looking for another solution like a section filter or other to select all the constraints or totes of the same type.
Hold down the Ctrl key, then click and drag to encompass a specific area. This reverses the selection state of all objects in the selection window. In other words, it allows you to select all objects that were not selected and to deselect all objects that were.
Otherwise, when a geometry is selected (without having selected all the constraints), you can access the "remove constraints" option, from the context menu (with a right-click). This does not remove the constraints of coincidence.
