ENTC 2170—Assignment 2-6:

Problem Solving with CADD

CADD applications are often used to solve engineering layout problems. In this assignment, you will use 2D CAD to determine (i) the center X-Y location of the circle (2-6A) and (ii) an approrpriate center of the nominal 1/8" DIA arc (2-6B). These types of problems are typical of a product design or manufacturing environment where (A) the path of a cutting tool must be calculated to create a specific geometry or (B) the location of a particular feature needs to be determined.
Click inside each image to open a larger PDF drawing in a new window. Rotate as required
Start each drawing from scratch (i.e., Open -> "No Template - Imperial"). Using the layer tool, create appropriately named layers (e.g., "Dimensions", "Assign 26A" and "Assign26B"). Create other named layers as desired to hold points and/or construction lines. Create the geometries on the appropriate layer(s) per the applicable drawing. To determine the X-Y coordinates of the center of each circle, use the AutoCAD Properties tool ([CTRL]+1 or click on the "Properties" icon on the Standard toolbar or Ribbon. Use the Dimension->Multileader function to place the center points' coordinates in each drawing. Save the drawing to the hard drive and back-up media. Submit them electronically to your instructor as directed.
