1 Sprts drink bttle Teachers ntes Pr/ENGINEER - Wildfire 3.0 Schls and Schls Advanced Editin This unit f wrk is based n unit 7C frm the QCA scheme f wrk fr design & technlgy. It shws hw CADCAM and Pr/ENGINEER in particular can supprt wrk in prduct design and graphics. Students are taught hw t create the bdy and cap f this bttle, assemble the parts and then prduce an engineering drawing. Within the cntext f a sprts drink bttle fr an athlete, this material teaches yu hw t use Pr/ENGINEER t create and assemble cmpnents and prduce an engineering drawing. The finished mdel can be manufactured using CNC r RP equipment. Wherever pssible students shuld have the pprtunity t make and test their designs. Learning bjectives By the end f the cmputer mdelling sessins pupils shuld: Be aware: Of the cncepts f 3D parametric slid mdelling using Pr/ENGINEER Of the engineering drawing capabilities f Pr/ENGINEER Be aware f prduct prttyping techniques Understand: The principles f 3D parametric slid mdelling including part creatin, assembly and drawing using Pr/ENGINEER Hw 3D slid mdelling sftware be used t refine designs including parts and assemblies.
