Mechanical The drawing shown is a fan with an enlarged view of the motor. This fan can have one of four motors of different sizes. Create the fan as a dynamic block. A. Draw all the objects. Do not dimension the drawing or draw the enlarged view. B. Create a block named FAN consisting of the objects shown in the dimensioned view of the fan. C. Open the block in the Block Editor and insert a linear parameter along the top of the motor (the 1.50″ dimension). Use a value set with the following values: ″ 1.125, 1.5, 1.875, and 2.25. D. Assign a scale action to the linear parameter. Select all of the objects that make up the motor as the objects to which the action applies. Use an independent base point type and specify the base point as the lower-left corner of the motor (the implied intersection). E. Save the block and exit the Block Editor. F. Insert the block four times into the drawing. Use the linear parameter grip to scale the motor to the four different sizes, as shown. G. Save the drawing as P26-8. 6.00 Ø1.00 .75 4.50 .50 1.00 1.75 2.25 5.00 A 2X Ø.20 .10 .37 .37 .50 .50 .75 .75 .35 1.30 .25 .25 .75 .75 .42 .42 .35 .35 Ø.50 DETAIL A SCALE 4:1 4X R.25 2.00 1.125 1.875 2.25 1.50
