CAD ApplicationsAssignment #13BSCALINGObjective:The student will construct a complete orthographic drawing of an assigned problem with METRIC dimensions.Assignment:¨ Construct a complete orthographic drawing including a FRONT view, TOP view, and RIGHT SIDE view complete with the necessary object lines, hidden lines, center lines and dimensions. ¨ The drawing will be done on size "B" drawing paper. Set one Layer for the border and title block. Set the limits for size "B" paper and insert the standard border and title block. When prompted for the X scale factor and the Y scale factor enter the multiplier value for a scale of 1” = 1mm.  Set the remaining drawing parameters, layers, colors, line weights, and linetypes as needed. Use the correct linetype assignments for each line type (i.e. CENTER2, HIDDEN2).¨ Create a layer for the dimensions with a color of the student's own selection. Be sure toinclude this layer on the CAD Drawing Document Sheet.¨ Set one layer for construction. This layer should be completed first. Draw the main center lines to locate key features of the object. Construct the drawing details as needed. Do not erase this layer. Be sure to include thislayer on the CAD Drawing Document Sheet.¨ Standard drafting practice requires center lines to extend 1/4" past the feature, not the entire object.  Construct the given problem. Use the Offset, Mirror, Copy, Move, Chamfer, Fillet, Array, Change, Pan, and Zoom commands to your best advantage. Extend, Trim, and Grips can also be used.¨ Plot the drawing on size “B” drawing paper.Special Instructions:¨ The drawing is drawn full size using a scale of 1” = 1mm. This will require the scaling ofthe TEXT heights, LINETYPES, and the DIM parameters for the finished plotted drawing using a size "B" sheet of drawing paper with a scale of 1mm=1mm. Record all values inthe spaces provided. ¨ TEXT HEIGHT: _______________ (for 1/8" high letters for general lettering)¨ LIMITS: ___________________________(for size “B” drawing paper (16.54, 10.60).)¨ LTSCALE: _______________ (for a finished scale of 1mm=1mm)¨ Insertion Scale factor (Border and Title block): _______________¨ DRAWING UNITS: ___________________________2CAD ApplicationsAssignment #13B¨ Do not use AutoCAD's default dimensioning parameters. In the Annotation ribbon select the Style option andcreate a new dimension style. Make this new style current.In the Lines section: Set the Baseline Spacing for 0.25 Set the Extend Beyond Dim Lines value to 0.125 Set the Offset from origin value to 0.0625In the Symbols and Arrows section: (Choose an arrowhead style) Set the Arrow Size to 0.125 Set the center marks to NoneIn the Text Section: Set the Text height value to 0.125 Set Vertical to "centered." Set the Horizontal to "centered." Set the text alignment to "Aligned with dimension line"In the Fit Section: Set the fit to "either the text or the arrows, whichever fits best"  Set to “Beside the Dimension Line” Set the “Use overall scale of” to 25.4In the Primary Units Section: Set the Unit Format to Decimal Set the Precision to 0.00 Add dimensions to the drawing using the CAD terminal. Space the first dimension line 10mm (10 units) from the object and 10mm (10 units) for all successive dimensions. Use the Offset command to establish the spacing requirements. Use GRIPS to reposition dimension text if necessary to avoid stacking. Add the given dimensions to the drawing using the Annotation ribbon. Use the DDEDIT command to edit dimension text to manually change or add text to a dimension. Use the PROPERTIES dialog box when you want to change content, text style, location, orientation, size, justification, and other properties. Plot the drawing with different line weights by assigning a line weight to a layer. Assign a line weight of 0.02 for object lines, a line weight of 0.012 for hidden lines, and a line weight of 0.010 (default) to all other lines.Evaluation: You should have one plot and one CAD Drawing Document Sheet for this Assignment.  Refer to the PROJECT EVALUATION handout for the required items to be turned in for evaluation.3CAD ApplicationsAssignment #13BVocabulary:QLEADER MTEXT UNITS GRIPS LTSCALE TEXTLEADER (LE) MLEADER DIMSTYLE (DST) DDEDITRules for Dimensioning: Use only the dimension given in the problem. Place dimensions on features where the feature shows true size and true shape. Do not place dimensions where they appear on the picture. Do not duplicate dimensions. Space dimensions uniformly. Space the first dimension line 10mm (10 units) from the object and 10mm (10 units) for all successive dimensions. Do not cross a dimension line.
