課程內容

第16章 SolidWorks 建模之草圖規則與型態【PPT】(SolidWorks Sketch Rules and Types in Modeling)
說明草圖影響特徵成形原因，草圖畫完→進行特徵時，草圖規則不合邏輯，系統出現訊息提示特徵無法成形原因，本章說明有順序性。

第17章 SolidWorks模型建模SOP【PPT】(SolidWorks Modeling SOP)
看到圖先別急著畫，當下決定從哪開始建模，口訣：先填→後除→鑽孔→再導角，面對複雜模型不再恐懼如何下手。避免每人說法不一樣，造成初學者用聽說來建模。

第18章 SolidWorks視圖最佳草圖輪廓【PPT】(SolidWorks Best Sketch Profile for Views)
本章與上章關聯，由模型得到建模順序後，利用工程圖找到要的草圖輪廓與尺寸，這才是最難的，要有識圖能力才可勝任，藉由PPT認識圖學知識，配合圖學課本學習更好。

第19章 SolidWorks最佳模型顯示狀態【PPT】(SolidWorks Optimal Model Display States)
本節網羅模型面相利用實務案例，學會取捨視圖，在視圖只能留下一個情況下，就要做出最有利決定，決定留誰並提出見解，這些和圖學有關。

第20章 SolidWorks特徵-伸長填料與除料觀念 (SolidWorks Feature Concepts of Extruded Boss/Base and Cut)
