Selecting an object or multiple objects is probably the most popular operation you would perform in Drawing Wireframe views, and a necessary first step in all other CAD operations you plan to perform on an object. Yes, selecting an object is as easy as clicking on one of its lines, but it is really important to know all the different selection methods, because many times there is a better way than just clicking on an object... (For more information on selection, refer to the "Editing Objects" section in the User's Guide). 1. Basic Selection: Click an object's line. 2. Selecting Multiple Objects with CTRL key: Hold down the CTRL key and click on an object, and another, and another.... 3. Selecting Multiple Objects with a Bounding box (Draw order LEFT TO RIGHT): This selects any object that is fully within the bounding box... If any objects are partially inside the bounding box, they are not selected... 4. Selecting Multiple Objects with a Bounding box (Draw order RIGHT TO LEFT): This selects any object that is fully within the bounding box or partially within the bounding box. 5. Selecting ALL objects on visible and editable layers: use CTRL + A 6. Selecting ALL objects on the current layer only: use CTRL + SHIFT + A 7. Cycle Selection: When multiple objects are overlapping each other, and you only want to select one of them, hold down the SHIFT button and click on a spot where multiple objects have overlapping or intersecting lines. (During this operation, the status bar in the bottom left corner displays: Cycle Selection: X of Y) 8. Right Click menu: it offers a list of library objects inserted in the file, which gives you a way to select all library objects of a particular type. 9. Select Special: this menu is available under the Edit menu in Drawing Wireframe, which offers special selection options, like "Specify Layers to Select" delivering the ability to specify multiple layers which have objects that you would like to select. (For more information on selection, refer to the "Editing Objects" section in the User's Guide).
