6. AutoCAD 2D 예제 - 초보자 가이드, 실습 및 튜토리얼

이제부터는 앞에서 조금씩 익힌 단축키를 사용해서 도면을 작성해 보겠습니다.

 

제가 항상 말씀드리는 거지만 CAD 또는 기계CAD, CAM을 이용할 때는 보조선 등이 중요합니다. 

 

아래 그림 같은 경우는 사각형과 중앙보조선, 대각선 보조선, Fillet, 원그리기, 복사 등이 필요합니다. 

 

천천히 생각을 해보신 후에 도면을 작성해 보세요. 

 

모깎기, 사각형, 원, offset, array, polyline

여기까지 혼자서 그리실 수 있으면 CAD 상에서 Free drawing 을 해보세요. 

 

예를 들면 내가 살고 싶은 집을 치수 상관없이 그려보신다던지, 내가 가지고 싶은 형태의 의자, 책상, 조명 등 다양한 것들을 

 

아무도 신경쓰지 말고 그리고 지우고를 반복하다 보면, 단축키가 손에 익고 모르는 것들은 한번 더 찾아보게 되니 엄청 빨리 배우더라구요.

 

힘내시고 차분히 하나씩 해보시죠!!!
