Selecting a builder object

You have to have a builder selected before you can select a builder object in that builder. Follow the Selecting a builder instructions to select a builder if you do not have the one you want selected.

Press the button to the left of Select to enter select builder object mode. Then left-click on any part of the builder to select that piece. Once selected you can use the transform widget to move and rotate the selected object. You can press the "editor transform widget mode" key binding (default e) to switch between the different transform widget modes. Once you have selected a builder object you can edit its properties by pressing the edit transform button and the edit object button.
