                                  I also have been using this software for more than three years. NX, formerly known as "UG", is an advanced high-end CAD/CAM/CAE. It is used Design (parametric and direct solid/surface modelling), Engineering analysis (static; dynamic; electro-magnetic; thermal, using the finite element method; and fluid, using the finite volume method), Manufacturing finished design by using included machining modules.<br />

+                                 ① Basic study<br />
+                                 About design and CAD in NX UG, I divide a design of 3D model as four steps (not include the CAD and product management process, just for a fun design or maker do).<br />
+                                 Step1: The first is to make a plan.<br />
+                                 Step2: Then do sketch base on this plane and add correct constrain to line and curve. I summarized the process of build sketch as shown in the following figure.<br />
+                                 <img src="img/week_02/Picture14.jpg" class="img-responsive" alt="..."><br />
+                                 Then I used the drawings in the book to practice the sketch module.<br />
+                                 <img src="img/week_02/Picture07.jpg" class="img-responsive" alt="..."><br />
+                                 <img src="img/week_02/Picture08.jpg" class="img-responsive" alt="..."><br />
+                                 Step3: Convert to 3D components by using stretch or rotate tools or use the voxel feature tools (such as cuboids tools and cylinders tools) for 3D modeling directly.<br />
+                                 <img src="img/week_02/Picture15.jpg" class="img-responsive" alt="..."><br />

+                                 Step4: Make this model by real physics process such as laser cutting,3D printing, NC or hand made. <br />
+                                 ② Parametrization design: five-pointed star<br />
+                                 First, I enter the sketch screen and draw the sketch of the five-pointed star.<br />
+                                 <img src="img/week_02/Picture17.jpg" class="img-responsive" alt="..."><br />
+                                 Then convert to 3D components by using stretch tools.<br />
+                                 <img src="img/week_02/Picture10.jpg" class="img-responsive" alt="..."><br />
+                                 Notably, I used expressions to control the length and height of the pentacle in the sketch modeling and stretch instructions.<br />
+                                 <img src="img/week_02/Picture18.jpg" class="img-responsive" alt="..."><br />
+                                 ③ Assembly<br />
+                                 Assembly is the assembly of multiple parts together to form a complete assembly, which is generally the final state of the market. Assembly in NX is the assembly of parts using "assembly constraints", which are similar to the geometric constraints on curves or points in sketches, with the end result that the parts are placed in the specified position.<br />
+                                 I'm going to use the "bottom to up" assembly method to practices.<br />
+                                 <img src="img/week_02/Picture11.jpg" class="img-responsive" alt="..."><br />

+                                 ④ 3C sample<br />
+                                 Finally, based on my previous work experience, I integrated many machining features of many 3C industries into one part, as shown in the following figure.<br />

+                                                        OpenSCAD is software for creating three-dimensional CAD objects. It is free software available for GNU/Linux, Microsoft Windows and apple OSX. OpenSCAD unlike most free software used to create 3D models (such as the famous Blender application), all the design is done by writting code.<br/>
+                                                        I think it is funny. Because of I have no basis in computer programming, I can only design some simple products. So, it can be really difficult to model complex surfaces for me. First, I learned the basic instructions of from OpenSCAD <a href="https://www.openscad.org/cheatsheet/"this Website</a>. Then, I mainly use cubes, spheres and Boolean operations. <br/>
