Do some 3D Modelling 1

creo 2.0 , some graphs to do . Homework 3 In the Modern Graphics Communication, on pg. 299, recreate the following parts as accurately as possible: Parts 7.7, 7.8, and 7.32 For each part, make a single A-sized drawing that provides a ‘top’, ‘front’, and ‘side’ projection views of the part, as well as an auxiliary view of the part. The auxiliary view should be one that shows a feature of the part that does not appear properly in the other views, and shows the true dimensions of that feature. For this assignment, you may ignore any rounds or chamfers shown on the parts. In addition, show the following dimensions on the auxiliary view of the drawing: Part 7.7 – the radius of the upper hole Part 7.8 – the 120 degree angle between the faces Part 7.32 – You will need two auxiliary views to show this part completely; one to show surface B, the other to show the dovetail cut into surface B. Grading will be based on the accuracy of the part and its dimensions, as well as showing the proper views of the part. Homework 4 In the Modern Graphics Communication, on pg. 245, recreate the following parts as accurately as possible: Parts 6.6, and 6.7 For each part, make a single A-sized drawing that provides a ‘top’, ‘front’, and ‘side’ projection views of the part. For this assignment, you may ignore any rounds or chamfers shown on the parts. For extra credit, provide a section view of the wheel from problem 6.6. Grading will be based on the accuracy of the parts and its dimensions, as well as showing the proper views of the part. -AND- I want you to make a simple 4-bar mechanism assembly. Model each part, and make a dynamic assembly of the sliding crank. Make one drawing showing an isometric view of the crank in 3 different positions.
