One plane will be displayed parallel to the screen (frontal), while the other two will appear as edge views (horizontal and profile).X=0, Y=0, Z=0 (0,0,0)Screen Layout in Part File ModeOne-line HelpDashboard & Message AreaToolbarsPull down menusRoll overSketching (Drawing) areaModel Tree & Navigation AreaSketching iconsSelection FilterDo Not Maximize – need room for dialog boxesSketch in Part File ModeCreating a sketch in a part file, File – New – Part – , allows the modeler to sketch a 2-dimensional cross section of the object and then add a third dimension by extruding, revolving, etc.–In the example to the right, the cross section of the part will be sketched on the frontal plane, giving us height and width. The profile and horizontal planes will be viewed as edge views, which means the third dimension, depth, can be added by extruding, revolving, etc.2-D Sketch OnlyA sketch may be created 2-dimensionally, File – New – Sketch, which means a the modeler may NOT add a third dimension.To learn how to sketch, trim/extend, drag, add and delete constraints and dimensions we will start with the 2-dimensional sketch mode only.–Advantages:»We don’t have to decide which plane to sketch on.»We don’t have to worry about where to start the sketch (origin).»If we accidentally draw a line on top of a line, leave a gap between two lines, etc., we can save the sketch and come back to it later. If we tried to extrude with these errors, we would not be able to extrude the sketch until all errors were corrected.–Disadvantage:»Only one sketch may be open at a time.Improved Intent ManagerInside Sketcher –Select appropriate sketching icon.–Move mouse to where entity will start/end and click mouse left mouse button, repeat until finished with drawing that type of entity–When finished sketching, select the Select icon. (Shortcut – select the middle mouse button)Watch for hints and/or instructions–Roll over (or message line)–Prompt lineSketching IconsLine: object, line 2 tangent, or center line–Click, release, move (or drag), click, etc.–Select icon or middle mouse button to endRectangle–Click (corner), drag/move, release, click (diagonal corner)Circle: circle, concentric circle, circle 3pt, circle 3 tangent, ellipse–Circle: click (center of circle), drag/move, click (point on circle)–Concentric circle: (share same center point): select existing circle, drag/move, release, click (point on new circle)Sketching Icons cont’d.Arcs: tangent & 3 pts, concentric, center/endpoints, 3 tangents, & conic–3pts. or tangent: select starting and ending endpoints, select point on line. If the arc is to be tangent, what for tangent relation symbol (T).–Concentric arcs:(share same center point): select existing arc, drag/move, release, click (point on new arc)–Center/endpoints arc: click (center of arc), drag/move, click (starting point of arc), drag/move, click (ending point of arc).Fillets and Rounds:–Select two entitiesDemo (For practice turn off dimensions and endpoints)Sketching Icons cont’d.Select Icon selected Any other sketcher icon selected, i.e., circle – X at end of cursorPractice Start a new sketch file.–File – New – Sketch – type in the file name Practice1) Using your Sketcher – Tools web print out, try all sketching icons, especially line, rectangle, and circle.–Watch constraints (condition defining the geometry of the entity, such as, horizontal, vertical, perpendicular, etc.)»When are they added?»What do the symbols mean?To close a sketch and start over.–Select the Continue icon.–Start a new sketch, increase the number behind the file name one number. I.e., Practice2It is more important to understand how to use each command than to sketch a real shapeDeleting Entities Select Select icon (Shortcut: Middle Mouse button)Several ways to select entity(ies) or constraint(s) –Click on entity or constraint–Use the Shift key to select multiple entities–Window entities (entity must be entirely inside box) –Select Edit – Select – AllSelect one of two methods–Press Delete key –Right mouse button & select DeleteRepaint screen icon (Shortcut: CTRL-R)–Cleans up screen clutter Practice deleting entities–If a sketch is open, close it–Start a new sketch (File – New – Sketch – type in a file name)–Draw different entities–Practice deleting them one at a time and multiple entities.Right Mouse Click OptionsTwo Sets of Commands–Top portion: editing, manipulations & selection –Bottom portion: creation commandsNot available in rubber band modeRight Mouse Click Options cont’d.Factors to Consider–What command is currently invoked–What kind of entity is selected–What is currently pre-highlightedSelect mode, blank drawing areaSelect mode, sketch startedLine mode, blank drawing areaLine mode, sketch startedRight Mouse Click Options cont’dSelect icon only Entity selected Dimension selectedPractice If a sketch is open, close it. Start a new sketch file.–File – New – Sketch – type in the file name Practice)Sketch multiple lines, rectangles, circles, etc.Practice right mouse selections.Practice deleting single and multiple entities.Close the sketch.Entity ColorsWildfire•Entities will be yellow•When the cursor is
