Ghost Paper Clip

<p><strong>Lesson Plan and Activity:</strong></p><p>Joel and I had to recreate a ghost clip we were given using Solidworks. We had to have identical files, which we did by collaborating on each step one at a time.</p><p><br><strong>Assembly/Construction Instructions Section:</strong>&nbsp;</p><ol><li>Create a construction center rectangle off of the origin.

Create another arc to the right of the previous arc. Use the same dimensions.</li><li>Mirror arcs in step 10 to the right across the y-axis.</li><li>Create a line within the construction box, smart dimension top point to the top left corner with the dimensions on drawing.</li><li>Create a diagonal line from the bottom point of the previous line. Smart dimension the bottom point of the new line to the bottom left corner of the construction box.</li><li>Use offset entities of the two lines and check off bi directional and check reverse.</li><li>Mirror steps 12-14 to the right of the y-axis.</li><li>Create solid lines from the bottom of the arcs at the top corners to the top of the diagonal lines at the bottom corners.</li></ol><p><strong>Design Choices:</strong></p><p>As we were designing, one issue we noticed was that we could only mirror things across the center of our model, not over any line. This was a problem with our semi-circles at the top, as we planned to make 1 and mirror it 3 times. Instead, we made two right next to each other, and mirrored both of those across. <strong><img src="https://lh3.googleusercontent.com/-xGDdFfc_GIrtISKA_LP_5KDAnmrq0iJhhEnNO6hgBiXHzcQlkgnawyKbI-yTvtG9Q76P4kCadA6B79Yyx2hxrCkmsxC6xonDlyjP6SR6ix31oNJyvMjUSbCVmAHac5odjopgDSHOTDB1zicLHGAGiypKBHxIRnv0nVagxSadXVkLj75CD9Eld74zxz8UQ"></strong>Another issue we came across was that our original plan did not involve using the offset entities feature, which was a requirement for this project. We were originally going to use basic shapes to create the left side of the mouth, then mirror everything to the right to complete it. Instead, we made the outer edge of the left side of the mouth, offset that inwards, and mirrored everything to the right. <strong><img src="https://lh5.googleusercontent.com/FPrfisGEmDNC7AWLinfc1kfWkWNB0o1lX1_7PG8yHQwu2dcB8xUu9VCWriOp6Htxoe367XciObb98ai5RVVkV8oFa6WAZIWxHWQWLSVQ1qhO5NExQnSdvrrvv3lyVN23MpoUXcg8hx8yr1hZsfMCP05s6pmQjoAIzeXiZfdUTpFd1t4RJxZ0aLQLTKoz0g"></strong></p><p>After we finished designing the ghost clip, we compared our models to the actual ghost clips we were given. The next change we made was moving the eyes down and inwards. We originally had the center of each circle 1.3 cm below the very top of the model, but we changed it to 1.4 cm to better match the dimensions of the actual ghost clip. The center was also 0.8 cm away from the side, we changed that to 0.85 cm</p><p>. <strong><img src="https://lh4.googleusercontent.com/nop4CiZgq-HFRgm9EaFbLhJaVjvGkreXwcKe92DfLMP_frFCgrD6LPTOxsSZV06ctSAWMwn1sAq2DetlAMBF4xiWBRXrLhD9AaY_Za1MC-1IzPNg2Bq4Y502JWOwxeVGnKyFpfmBxaffC_t99Aj-wUlMNmKHPaz1Iz4GIt4RYMzO_SgUYW1vMgzKSRvKYg"></strong></p><p>We then did the same thing with the mouth, moving it down 1 cm to make it 0.8 cm from the bottom of the model rather than 0.9 cm. Lastly, the mouth had to be made a little smaller, so we moved everything on the left side of the ghost clip 0.1 cm to the left, and the mirroring allowed the same thing to happen on the right.</p><p><strong><img src="https://lh5.googleusercontent.com/fG-9QtIhYPiXdzqs-Sti24ypsyllmzt__d3akqef3j6_tf7GWTMbcDiwyzup0x-3wupCOdaQfDzOLWdvVFRYskDGgXXDxDgdP51Gy9vTSfDT7mN_O0KeWhruPdQ4G7ZNpW2FuKetf8NaUbA-ZH34FjvNzaLsQpcI0QsQPjceyX3t0IU-6vJipmIdr6EsCw"></strong></p><p><br>&nbsp;</p>
