3. Computer Aided design¶
abstract: The target of this week is learning what is computer aimd design and practice the list of tools.To know how CAM or CAD could help poeple to build a solid or plane object then fullfill whole physic demand on real world, i choice the Fusion 360 as the main tool for familiar with Autodesk system by TinkerCAD and 123D design. My conclusion is that Fusion360 is easy to sketch an design and make correct constrain, the awesome is it can help me to export as the 3D file as .stl or .obj by cura,meshmixer and so on.

About design and CAD
in my opinion, i divide a design of 3D model as 4 steps(not include the CAD and product management process, just for a fun design or maker do).the first is to build a plane.
then do sketch base on this plane and add correct constrain to line and curve. this step is important because constrain could promise the sketch keep correct after extruct into 3D Models. beside use extruct from 2D sketch, we also can build solid from create solid such as ball or even circuler pattern.in the third step to convert to 3D components, the situation would be complex.our last task is to know how to make this model by real physics process such as laser cutting,3D printing,CNC or hand made.
About Fusion360
the feature of Fusion360 is sympathic because this products is called tailord for makers.
Autodesk is not open source product that is why i think Nail didnt recommand to use lol. however, it has free experience version for student and teacher.so i use my student id to get it easily.before you downlaod the sofware. your should get licence and sign up an autodesk account to finished beforcehand process.
there is so much design tutorial on youtube , website or Autodesk community. to prevent my skill i attend a free course on udemy learning how to make a real component.
the result i do is such a wheel plate which sketch the shape from xz plane and add some comstrain and real diameter to clearfy the size. next step is to extrude to solid and fixed the pullet.
another important concept is boolin much parts of object.it’s sometime defuse me to distinguish add new component,combine and else. the tip to certainfy is check the list about construct and sketch in your left screen. it’s work to make sure which part is for which and even check the version of one subject.
