Drawing Area: Area where you draw (How surprising) Drawing Area: Area where you draw (How surprising) Status Bar: Displays the cursor coordinates in the lower- left corner. Also contains buttons to turn on common drawing aids (Snap, Grid, Ortho, Polar, Osnap, etc…). Status Bar: Displays the cursor coordinates in the lower- left corner. Also contains buttons to turn on common drawing aids (Snap, Grid, Ortho, Polar, Osnap, etc…).

Drawing Aids Grid and Snap Grid Grid: Area of the graphic covered with regularly spaced dots, acting as visual reference. Grid: Area of the graphic covered with regularly spaced dots, acting as visual reference. Snap Grid: Invisible grid that locks the pointer into alignment with the grid points according to the spacing set by Snap. Snap Grid: Invisible grid that locks the pointer into alignment with the grid points according to the spacing set by Snap.Note: Both options can be turned On/Off from the Status Bar. Both options can be turned On/Off from the Status Bar. Grid and Snap Grid are independent options; and grids spacing do not have to coincide. Grid and Snap Grid are independent options; and grids spacing do not have to coincide. Grids shape and spacing can be specified from ‘Tools’ menu, choosing ‘Drafting Settings’; or with command line ‘Dsettings’; or by right-clicking on the Status Bar Grids shape and spacing can be specified from ‘Tools’ menu, choosing ‘Drafting Settings’; or with command line ‘Dsettings’; or by right-clicking on the Status Bar

Drawing Aids (cont’d) Object Snap Object Snap: Option used to snap the cursor to particular points on objects, i.e. end points, centers, etc… Object Snap: Option used to snap the cursor to particular points on objects, i.e. end points, centers, etc… The option can be turned On/Off from the Status Bar. Three Object Snap methods: From the Standard Toolbar, by clicking on a button of the Object Snap flyout. From the Standard Toolbar, by clicking on a button of the Object Snap flyout. Press SHIFT and Right-Click near the point intended to snap to; and then choose an object snap from the shortcut menu. Press SHIFT and Right-Click near the point intended to snap to; and then choose an object snap from the shortcut menu. Enter an object snap abbreviation on the command line (END, MID, INT, etc…). Enter an object snap abbreviation on the command line (END, MID, INT, etc…).

Drawing Aids (cont’d) Grips and Ortho Grips: Small squares that appear on selected objects. By selecting a grip and dragging the mouse, you can stretch or move the object. Grips: Small squares that appear on selected objects. By selecting a grip and dragging the mouse, you can stretch or move the object. Use Esc key twice to deselect grips. Ortho: Option that locks the cursor’s movement along the x,y directions on the screen. Ortho: Option that locks the cursor’s movement along the x,y directions on the screen. The option can be turned On/Off from the Status Bar.

Selection Modes Selection Modes: Selection Modes: – All. – Window. – Last/Previous. – Crossing. – Box (Equivalent to ‘Crossing’ if selection from right to left; otherwise equivalent to ‘Window’). – Fence (Selects all crossing objects). – WPolygon (Selects all objects completely inside polygon). – CPolygon (Equivalent to a closed fence).

Zooming Zooming Modes (Zoom Command): Zooming Modes (Zoom Command): – Zoom Window (W). – Zoom Dynamic (D). – Zoom Scale (S). – Zoom Center (C) (Specify center point and height). – Zoom In/Out (2X /.5X). – Zoom All (ALL). – Zoom Extents (E).

Draw Objects Draw Objects: Draw Objects: – Line – Polyline – Rectangle – Arc – Circle – Polygon – Ellipse – Etc.

Objects Editing Methods Modifying and Editing Commands: Modifying and Editing Commands: – Trim – Stretch – Break (Erases parts of objects or splits an object in two) – Fillet (Rounds and fillets the edges of objects) – Chamfer (Equivalent to Fillet with a straight edge) – Extend (Extends an object to meet another object) – Mirror – Array (Creates multiple copies of objects in a pattern) – Offset – Explode (Breaks a compound object into its component objects) – Etc.

Layers Layers properties: Layers properties: – Color – Linetype – Lineweight – PlotStyle Layers control methods: Layers control methods: – Freeze (Freezes layers, making them invisible and excluding them from regeneration and plotting) – Lock/Unlock (Locks layers, preventing selection and editing of objects on those layers) – On (Makes selected layers visible and available for plotting) /Off – Plot

Blocks Blocks: association of multiple objects into a single entity (e.g. door, window, etc.) Blocks: association of multiple objects into a single entity (e.g. door, window, etc.) Blocks Methods: Blocks Methods: – BLOCK: creates block definitions on the command line – Insert Block: specify the insertion point, scale, and rotation angle – Explode Block: breaks a block instance for modification, I.e. to add or delete objects that define the block – Oops: restores objects erased by the last ERASE command – Wblock: Writes objects or a block to a new drawing file

What’s New in AutoCAD 2000 Design Environment: Design Environment: – Multiple document environment (Work with multiple drawings in a single environment) – New object snaps (Parallel and Extension object snaps) – Real-time 3D rotation – Toolbars (Use AutoCAD toolbars that are enhanced to conform to Microsoft® Office 98 standards) Improved Access and Usability: Improved Access and Usability: – Properties window – Shortcut menus(Right-click your pointing device to display new shortcut menus to access AutoCAD commands) – Text editing (Use the new text-control capabilities of the Multiline Text Editor to edit text more quickly) – Load/Unload applications (The new Load/Unload Applications dialog box makes loading and unloading applications easier and more intuitive) – VBA
