嘗試用Autocad 畫圖最有效率的方法 (Command study)

Cantonese Autocad course 1 (畫圖準備簡介)

因為見Civil 3D 個概念差唔多。

 一早用block的方法整定圖框A0-A4。放在一個file中。

在model 中畫工程的資訊，在Layout 度擺圖紙同埋圖紙資訊，因為果D唔駛轉scale

然後，(㩒m>v>space bar) 拉一個框， 設定想要的工程model圖scale再將mv的框較成unprint，咁就睇唔到個框喇。

補充: 個圖框template 應該整好哂D layer 線粗同線名，方便人使用。同整好D unit (襟 u>n>space bar)

係可以學microstation 咁， Model 用自己ga 線 style，跟住xreference 設定override ga 線style.

Cantonese Autocad course 2 (無論用咩板本ga Autocad，畫圖形快捷鍵)

畫直線1: l>space bar 跟住係畫面度點出想要ga 圖形，D直線會分開一條條

畫直線2: p>l>space bar 跟住係畫面到點出想要ga 圖形，D直線會痴埋一齊，仲可以較線粗

畫長方框: r>c>space bar

再慢慢整，整左幾部youtube,  但已經不需要用autocad 了。。。
