1.  What’s the quickest way to learn more about each feature in the toolbar?
   (什麼是最快的方式了解工具欄的所有功能)
   
   Hover the mouse over it for a second, and a description of the feature will pop up.
   (將鼠標停在上面一秒，並彈出該功能的說明)
   
   
2. Briefly describe the four foundational features. Feel free to draw pictures if it helps:
   (簡要描述四個基本特徵，可以隨意畫製圖片幫助說明)
   
   Extrude(擠出): This geometry is created when a constant cross section is extruded in astraight direction:(沿著直線方向擠出恆定橫截面)
   
   Revolve(迴轉): This geometry is created when a constant cross-section is revolved around an axis of revolution.(恆定的橫截面圍繞旋轉軸旋轉)
   
   Sweep(掃掠): This geometry is created when a constant cross-section is swept along a path(沿著路徑掃出恆定橫截面)
   
   Loft(混成): This geometry is created when multiple cross sections are smoothly connected together.(多個截面平滑地連接在一起)
   
   
3. What is the default geometry in a Part Studio?
   (Part Studio中的默認幾何體是什麼)
   
   The origin and three orthogonal planes: Top, Front, Right
   (原點和三個正交平面：上視，前視，右視)
   
   
4. What’s the difference between a box select from Left-to-Right and a box select from
   Right-to-Left?
   (從左到右框選和從右到左框選有什麼區別)
   
   L-R = selects everything within the box(選擇框選內的所有內容)
   
   R-L = selects everything the box touches.(選擇框選接觸的所有內容)
   
5. Can a document in Onshape have multiple Part Studios?
   (Onshape中的文檔可以有多個Part Studios嗎)
