When running the “Select by object name” command, a pop-up window appears where the user is allowed to pick the object name(s) that he or she would like to select eventually. When the user pre-selects one or more objects and run the “Select by object name” command, once again Rhino will bring the same window. This is good and useful, because it lets you add more objects to the current selection.
It would be even better to have an alternative command which allows to directly select all the objects of the same name in the scene when at least one *named object is already selected. Lets say the user selects objects named “RH-1-NO” and “RH-1-YES”. Pressing the “Select by object name” icon with the LMB will bring the classic selection window. However, pressing the same icon with the RMB could run “Select by same object name” command to select the remaining objects that share the same name as the pre-selected ones. This is especially helpful in scenes with hundreds or thousands of named objects where the user would spend way too much time in browsing across the long list inside the regular selection window to find out the desired object names.
P.S.: *If the selected object has no name, then the “Select by same object name” command could select all unnamed objects in the scene.
