Same as <return>. • Right button click:– context-sensitive drop-down menu85MAE 455 Computer-Aided Design and DraftingActions and Object Selection• There are two themes for selecting objects:1) Pick objects then select action2) Select action then pick objects– Most Office software uses (1)– CAD software uses combination of (1) & (2)• In NX, the steps of a task may also be identified by:– Sections of a dialog box.– A row of buttons.You can go back to a previous step by pressing the button for that step.9MAE 455 Computer-Aided Design and DraftingSelection Filtering• Use the controls in the selection bar to filter which objects can be selected:106MAE 455 Computer-Aided Design and DraftingControlling Object AppearanceThe visual appearance of objects can be controlled by selecting “Edit”  “Object Display.” Can control:– Line styles– Color– Translucency – Surface textures (with Visual Studio)11MAE 455 Computer-Aided Design and DraftingUsing Layers• Each NX object exists on a layer:Layers 1-20 Solid geometryLayers 21-40 Sketch geometryLayers 61-80 Reference geometry...• When a new object is created, it is put on the “Working Layer”• Use “Format”  “Move to Layer…” to move objects from one layer to another.• Use “Format”  “Layer Settings…” to set each layer as: “Working layer”, “Invisible”, “Selectable”, or “Visible only”127MAE 455 Computer-Aided Design and DraftingBasic Solid Modeling Process1) Create datum planes2) Create a sketch on a plane3) Sketch curves4) Constrain curves5) Perform Sweep6) Repeat 2-5 a few times to get basic shape.7) Shell the basic shape if necessary.8) Add fillets and
