      Coordinates

      The coordinates display the location of the cursor in reference to the Origin. The Origin is currently in the lower left corner of the drawing area. These numbers will change as you move the cursor.

      First set of numbers represents the horizontal movement of the cursor (X axis).

      Second set of numbers represents the vertical movement of the cursor (Y axis).

      Third set of numbers represents the Z axis, which is used for 3D and not discussed.

      Model

      The Model / Paper button allows you to work in either Model Space or Paper Space without leaving the Layout Tab. When you switch to a Layout Tab this button automatically switches to Paper.

      Grid (You may also use <F7> to toggle on or off)

      The criss-cross lines in the Drawing Area are called the Grid. It is only a drawing aid and will not print. The default spacing is 1 unit of measurement. You may change the Grid spacing at any time by typing DS then press <Enter>, then select the Snap and Grid Tab from the Drafting Settings dialog box.

      Snap Mode (You may also use <F9> to toggle on or off)

      Increment Snap controls the incremental movement of the cursor. If it is on, the cursor will "snap” in an incremental movement. If it is off, the cursor will move smoothly. You may set the increments by clicking on the down arrow and selecting Snap Settings.

      You can also choose whether to use Grid Snap or Polar Snap on the same menu.

      Infer Constraints (Note: Not used in this Workbook.)

      Inferred Geometric Constraints automatically applies coincident constraints for Endpoint, Midpoint, Center, Node, and Insertion Object Snaps.

      Dynamic Input (You may also use <F12> to toggle on or off)

      When Dynamic Input is on, you can enter coordinate values in tooltips near the cursor. More on this in Lesson 11.

      Ortho Mode (You may also use <F8> to toggle on or off)

      Ortho restricts the movement of the cursor to Horizontal or Vertical. When Ortho is on the cursor moves only in the horizontally or vertically. When Ortho is off the cursor moves freely in any direction.

      Polar Tracking (You may also use <F10> to toggle on or off)

      Polar Tracking restricts cursor movement to specified increments along a polar angle. More on this in Lesson 11.

      You may set the increments by clicking on the down arrow and selecting Tracking Settings, or you can select one of the predefined angles from the list.

      Isometric Drafting

      Isometric drawing allows you to simulate a 3D object by aligning along 3 axes, these are Top, Right and Left, called Isoplanes. When the button is enabled you can toggle the Isoplanes by pressing the <F5> key. Isometric Drafting is discussed in the Advanced AutoCAD® Exercise Workbook.

      You may also change Isoplanes by clicking the down arrow and selecting from the menu.

      Object Snap Tracking (You may also use <F11> to toggle on or off)

      Object Snap Tracking controls the display of Object Snap reference lines, AutoSnap marker, tooltip and magnet.

      2D Object Snap (You may also use <F3> to toggle on or off)

      When 2D Object Snap is on the cursor will "snap” to preset locations on 2D objects. More on this in Lesson 4.

      You may also add or remove Object Snaps by clicking the down arrow and selecting from the menu.

      Lineweight

      Lineweight displays the width assigned to each object. When it is on the lineweights are visible. You can change the lineweight settings by right clicking on the button and selecting Lineweight Settings. More on this in Lesson 3.

      Transparency

      When Transparency Show/Hide is on all transparent layers will be displayed. If it is off, no layers will display as transparent. More on this in Lesson
