- 附錄B：導航說明檔，建立帳號，訂閱計劃
特徵列 : 建立幾何特徵的順序
零件列 : 這個文件檔裡面的零件，按時間順序排列
標籤 : 可以有很多的零件、組合、圖面…
圖像區 : 可以建立和修改幾何的地方
方位視角 : 選轉&看不同角度

- 總結
Let’s take a second to reflect what we learned in this lesson.
1. We learned about the sketch-based modeling and the 4 foundational features (extrude,revolve, sweep, and loft).
2. We made our very first sketch.
3. We learned about selecting and deleting sketch entities(實體).
4. We learned about snapping sketch entities to draw more accurate sketches.
Next week, we’ll be talking about dimensions and constraints, expanding(擴大) more on the idea of creating accurate sketches.
Week1 Homework
Week1 Assessment
Q : What’s the quickest way to learn more about each feature in the toolbar?
A : Hover the mouse over(將鼠標懸停在上面) it for a second, and a description of the feature will pop up.
Q : Briefly(簡要) describe the four foundational features. Feel free to draw pictures if it helps:
A : Extrude: This geometry is created when a constant cross section(截面) is extruded in a straight direction
Revolve: This geometry is created when a constant cross-section is revolved
around an axis of revolution.
Sweep: This geometry is created when a constant cross-section is swept along a
path.
Loft: This geometry is created when multiple cross sections are smoothly
connected together.
Q : What is the default geometry in a Part Studio?
A : The origin and three orthogonal(正交) planes: Top, Front, Right.
Q : What’s the difference between a box select from Left-to-Right and a box select from
Right-to-Left?
A : L-R = selects everything within the box,
R-L = selects everything the box touches.
Q : Can a document in Onshape have multiple Part Studios(多個零件)?
A : Yes.
