ICT QUIZ #1

• Using Edgemode

  If the line you are trying to extend does not intersect with the boundary line,

  you can use the "Edge" opt-

  ion to toggle Edgemode to

  "Extend" (the default is "No

  Extend") .
• Shift Selection with Trim and Extend

  You may have noticed during the command sequ- ences for the Trimand Extend commands that you have the option to "shift-select" .
• The Chamfer Command

  enables you to create a chamfer between anytwo non

  parallel lines as in the illustration below or any two adjacent polyline segments.
• The Fillet Command

  is a very useful tool which allows you to draw an arc between two intersecting lines or adjacent polyline segments.
• The Explode Command

  is used to "explode" single objects back to their constituent parts.
• Endpoint

  snaps to the end points of lines and arcs and to polyline vertices. This is one of the most useful and commonly used Osnaps
• Midpoint

  snaps to the mid points of lines and arcs and to the midpoint of polyline segments.
• Intersection

  snaps to the physical intersection of any two drawing objects (i.e. where lines, arcs or circles etc. cross each other) and to Polyline vertices
• The Break Command

  enables you to break or remove part of an object by defining two break points.
• Apparent Intersect

  snaps to the point where objects appear to intersect in the current view.
• Extension

  enables you to snap to some point along the imaginary extension of a line, arc or polyline segment
• QUADRANT

  snaps to one of the four circle quadrant points located at north, south, east and west or 90, 270, 0 and 180 degrees respectively.
• Tangent

  snaps to a tangent point on a circle. This osnap works in two ways. You can either draw a line from a point to the tangent point (see illustration) or you can draw a line from a tangent point, the latter is referred to as the "Deferred Tangent" snap mode.
• Parallel

  used to draw a line parallel to any other line in your drawing. In operation, this osnap is slightly less intuitive than some of the others
• Insert

  snaps to the insertion point of a block, text or an image.
• Nearest

  This Osnap is useful if you want to make sure that a pick point lies on a drawing object but you don't necessarily mind exactly where it is located.
• Using the From Object Snap

  can be used in connection with other osnaps or ordinary pick points and relative co-ordinates to pick offset points.
• Running object snaps can be configured using the Object Snap tab of the Drafting Settings dialogue box, illustrated on the next page. This tab dialogue box and also includes settings for Snap and Grid and for Polar Tracking.
• None Osnap is not an osnap in the true sense of the word. It is really an osnap utility but it can be very useful when your drawing becomes complicated and it becomes impossible to pick the point you need without snapping to some other point
• The autoSnap features can be controlled by using the drafting tab of the options dialogue box.
• The Use of Object Snap Cycling

  is used to construct accurate drawings. However, when drawing become very complex, it can be quite difficult to pick the exact point you want
• The Use of Temporary Tracking Points

  similar to the From Object Snap which can be used to avoid the necessity of drawing construction lines in order to locate points
• Object snap tracking is use as temporary tracking points.
• The Use Point Filters

  The point filters are another set of tools which can save you lots of time by allowing you to specify the third co-ordinate of any point picked in a 2D plane
• Dimensioning the Object AutoCAD provides a whole range of dimensioning tools which can be used to quickly dimension any drawing without the need for measurement
• Two styles of dimension

  Standard. It is a default style. The dimension line has arrow heads and the dimension text is positioned above the line and is drawn using the current text style.

  Obliques. It is called obliques because the arrows at both ends of the dimension line are changed into a straight lines in oblique position and the vertical alignment of the text has been centered.
• Linear dimension commands are used to dimension along straight lines. There are five linear dimension commands, namely: 1. Dimlinear 2. Dimcontinue

  3. Dimbaseline 4. Dimaligned Dimrotated
• The Baseline Dimension Command

  You can use this command to generate a series of dimensions from a single base point.
• The Aligned Dimension Command

  You can use this command to generate aligned dimensions
• The Diameter and Radius commands are supplemented by the DIMCENTER command which can be used to add a center mark to any circle or arc. The DIMDIAMETER and DIMRADIUS commands do not automatically draw a center mark
• The Angular command is amazingly flexible and can be used to indicate an angle in almost any situation.
• The Use Ordinate Dimensions are not really dimensions because they do not indicate a measurement. Rather they annotate known as co-ordinate points. The DIMORDINATE command is used to indicate the X and Y ordinate
• Annotation with Leaders Ordinate dimensions are not really dimensions at all in that they do not indicate a measurement. Rather they annotate known co-ordinate points. The DIMORDINATE command is used to indicate the X and Y
• The Oblique option is used to set the dimension lines at an angle
• The Rotate option can be used to rotate dimension text about its center point
• Dimension styles are the main method used to control the way dimensions look
• The Dimension Update command is used to apply the current dimension style to existing dimensions. You can use this command to change the style of a dimension.
• Object linking and embedding is a way to use information from one application in another application.
• Embedded Objects OLE object is a copy of information from another document
• A linked object is a reference to information in another document
