準(zhǔn)確來說，那塊是廣角擴散板，密集四棱面結(jié)構(gòu)的透明塑料板一塊 打下來之后430EX的變焦功能自動關(guān)閉，焦距鎖定在14mm，照射角度加大了，但同等輸出功率下的照射距離減少了，一般用廣角拍合照或者引閃制造大面積光源的時候用。

3. 佳能430exii閃光燈說明書

閃光燈，如果只配一個的話，建議原廠的，指數(shù)越改越好。建議稍微攢攢錢,閃光燈不是只在暗光用的哦,只要是拍人無論室內(nèi)室外光線明暗都要用到的;所以必須要有高速同步功能 否則你6D最高同步速度1/180會讓你很惱火的,那樣的話 你室外完全無法使用的。

推薦佳能430EXII這個是最便宜的能滿足日常使用的閃光燈

隨著計算機應(yīng)用技術(shù)的飛速發(fā)展，計算機輔助設(shè)計已經(jīng)成為現(xiàn)代工業(yè)設(shè)計的重要組成部分，AutoCAD軟件具有操作簡單、功能強大等特點，它已被廣泛應(yīng)用于機械設(shè)計，建筑設(shè)計，電子等圖形設(shè)計領(lǐng)域，那么怎樣才能學(xué)習(xí)好AutoCAD繪圖呢？

學(xué)前準(zhǔn)備

CAD軟件選擇

在正式學(xué)習(xí)之前，我們先要做一步準(zhǔn)備工作，就是找到一款屬于自己的CAD軟件。

雖然現(xiàn)在市面上CAD有很多盜版可以使用，但是建議大家使用正版的CAD軟件，一是設(shè)計者都應(yīng)該有支持正版的意識，另一方面就是正版軟件會減少很多后顧之憂，相對來說會更加安全。

建議可以選擇CAD2004、CAD2007等，這些老一點的版本是經(jīng)過多次修正過的，在技術(shù)、用戶體驗方面要比新的版本好用。

學(xué)習(xí)步驟

學(xué)習(xí)CAD制圖，我們從淺入深可分3個階段進行。

掌握基礎(chǔ)操作

熟悉CAD的繪圖命令、掌握CAD軟件操作邏輯。這就像我們學(xué)認(rèn)字、寫字一樣，先掌握基礎(chǔ)的筆畫、筆順開始。

制圖常用的基本命令1

CAD繪圖命令：

CAD修改命令：

CAD尺寸標(biāo)注命令：

視窗縮放：

對象特性：

常用CTRL快捷鍵：

常用功能鍵：

制圖常用的基本命令2

1、繪圖欄上數(shù)下第一命令是——直線，快捷鍵L，不分大小寫。直線命令是我們最常用的命令，也是繪圖的基礎(chǔ)中的基礎(chǔ)。若要繪制直線，請單擊“直線”工具；

在繪圖區(qū)域用鼠標(biāo)左鍵單擊一次，其目的是為了指定直線線段的第一個起點；松開鼠標(biāo)，往任意方向拖動，線段會跟著拖動幅度變長變短；

這時，我們會看見直線的旁邊有一個白色的輸入框，里面的數(shù)值會隨著我們的拖動幅度而變化，這里面的數(shù)值代表是直線的長度，我們可以在里面輸入任意數(shù)值確定直線長度，然后按Enter或者空格鍵完成一條直線的繪制。

2、第二個命令是——構(gòu)造線?？旖萱IXL，它是為下一步的復(fù)制，鏡象等作為基準(zhǔn)的直線，虛線不屬于圖的輪廓線，一般是作為圖形某一點為中心的軸線。若要繪制構(gòu)造線，方法如下：

在繪圖工具中點擊構(gòu)造線工具。

依次在繪圖板中點擊一下鼠標(biāo)可見構(gòu)造線。

3、第三個命令是——多段線?？旖萱IPL，它由多條線段(可以是直線，也可以是弧線)組成一個整體的線段。如想選中該線段中的一部分，必須先將其分解。平常作圖經(jīng)常用到，就連做地形圖時也需要它，所以是很重要的命令。

要繪制多段線，輸入多段線命令敲擊多段線命令PL，敲擊空格鍵。

繪制多段線在CAD繪圖區(qū)指定直線的起點，輸入多段線的長度，敲擊空格鍵即可。

4、第四個命令是——正多邊形?？旖萱IPOL，顧名思義是可以繪制多邊形，點擊命令，輸入邊的數(shù)量，然后選擇內(nèi)切圓或者外切圓，就可以繪制了。繪制步驟如下：

1/5要繪制正多邊形，需要輸入命令：“POL”-“空格”，也可以在頂部的選項卡中找相應(yīng)的按鈕點擊，但是有點麻煩。

2/5命令行這個時候會提醒你：輸入側(cè)面數(shù)。這個側(cè)面數(shù)的意思，就是多邊形的邊數(shù)，幾個側(cè)面，就是幾邊形。這里輸入6。

3/5接下來就是按照提示：指定多邊形的中心，這個應(yīng)該好理解，可以通過鼠標(biāo)點選，或者鍵盤輸入坐標(biāo)的方式來指定中心。

4/5命令行提示：內(nèi)接于圓，或者外切于圓。因為AutoCAD表征多變形的特征是通過內(nèi)接圓/外切圓的直徑來的，所以這里要指明。我們選外切圓。

5/5這個時候，就需要指定外切圓的直徑了，我們通過鼠標(biāo)點選的方式來完成指定，就可以繪出正六邊形了。

5、第五個命令是——矩形?？旖萱IREC，可以快速繪制出矩形寬，這個也是很常用的一個命令。

在功能區(qū)單擊矩形按鈕，然后再繪圖區(qū)域任意處點擊，確定矩形的一個角點，然后拖動鼠標(biāo)，在任意處點擊，確定第二個角點位置，這時矩形就繪制完成了。

6、第六個命令是——圓弧。快捷鍵ARC，繪制圓弧命令可以快速畫出弧線，示意門之類的地方很常用。

首先打開軟件，然后在命令行輸入快捷鍵命令：ARC，按回車鍵確認(rèn)，根據(jù)命令行提示在繪圖區(qū)域指定圓弧的起點或 [圓心(C)]，接著繼續(xù)指定圓弧的第二個點或[圓心(C)/端點(E)]，即可完成圓弧的繪制了。如下圖所示：

基本操作邏輯

一、選擇邏輯

如圖，這里我繪制了一些直線、圓、矩形。單擊其中的一個圓與一條直線，它們變成了被選中的狀態(tài)。

但是如果元素特別多，那一個一個單擊顯然不現(xiàn)實，如下圖請你一個個單擊給我看。

這時候就要用到框選了。在CAD中，框選有兩種形式，這里以下面的圖為例來解釋。

1是從左往右按住鼠標(biāo)左鍵框選，此時選框呈藍色，這種形式下只有框選的圖形完全被框住才能被選中。

如圖，我完全框住了前三條直線，但第四條沒完全框住，此時被選中的只有前三條線。

2是從右往左按住鼠標(biāo)左鍵框選，此時選框呈綠色，這種形式下只要接觸到被框選的圖形，它就會被選中。

同樣的，我們從右往左框住前三條線，第四條線只框一半如圖，此時即使第四條線沒框全，但選框接觸到它也能被選中了。

這里插一點，如果你框選以后想取消選擇，只需按ESC即可。

如果你只想取消部分圖形的選中狀態(tài)，只需按住shift再將你想取消選擇的圖形進行框選（邏輯同樣是上面兩種形式），此時被框中的圖形就會取消被選中的狀態(tài)。

這樣的兩種框選模式看似簡單，但學(xué)會實際運用它們是能大大提高你的畫圖效率的。

下面我舉個簡單的例子，如圖，一個矩形中有許多交叉的直線。如果我只想選中直線的部分，而不想選中矩形怎么辦？這里提供兩種思路。

1、在矩形內(nèi)部，從右往左進行框選使選框接觸到所有直線，這樣即使直線外部未被框柱，所有直線還是會被選中

2、先從左往右把所有元素選中，再按住shift從右往左框選，只接觸到外部矩形的部分，將它取消選中狀態(tài)。

二、鍵盤命令

取消、刪除、撤銷、重做。任何繪圖軟件都離不開以上四種操作，這里我將CAD這四種操作的快捷鍵告訴大家。

取消：ESC

刪除：Delete

撤銷：Ctrl+Z（撤銷多步就多按幾次）

重做：Ctrl+Y(重做一般與撤銷搭配使用，如果你撤銷多了一步，按重做會回到上一步)

三、鼠標(biāo)中鍵

1、雙擊鼠標(biāo)中鍵：顯示全部圖形對象。

2、按住鼠標(biāo)中鍵拖動鼠標(biāo)：移動圖紙

此時十字光標(biāo)會變成一只小手，你可以通過拖動鼠標(biāo)來移動圖紙。

3、滾動鼠標(biāo)中鍵：縮放圖紙。這個大家應(yīng)該都懂，縮放圖紙與上面的拖動圖紙配合使用，方便你找到圖形的位置。

4、命令欄

CAD這個軟件，在我看來最重要的就是它的命令欄。

幾乎你畫在圖上的一切東西都與它有關(guān)。首先它的位置在之前講過，位于CAD界面的下方，共兩欄。上面一欄表示已結(jié)束的命令，下面一欄表示現(xiàn)在的命令。

CAD的命令欄，就相當(dāng)于一個你的助手，它會指引你做每一步操作。下面舉個簡單的例子。

如下圖，首先我們選擇CAD左側(cè)繪圖工具中的直線。（可直接鍵盤上輸入L再按空格/回車）此時命令欄第二行提示指定第一個點。

我們在繪圖區(qū)空白處單擊一下，此時命令顯示為指定下一點或放棄U。（由于這條線還沒畫完，此時第一欄并沒有內(nèi)容，即沒有上一步命令）此時你再選繪圖區(qū)另外一點，一條直線就畫完了；如果你輸入U，則放棄繪制這條直線。

而此時命令欄還是提示指定下一點或放棄。這里你有兩種選擇。1是單擊空格/回車鍵，則線段繪制完畢。2是繼續(xù)選擇另一點，那么就會出現(xiàn)兩條線。

此時命令欄的提示多了一項：閉合C。如果你鍵盤輸入C，則兩條線段頭尾相接，不在一條直線上則形成三角形。

這里注意兩點：

繪制完圖形對象后，再單擊空格或回車鍵，即可結(jié)束整個命令。如果你想重復(fù)上一次的命令，比如想繼續(xù)畫線段，只需再按下空格，會自動重復(fù)上一次指令。此時又要開始選擇線段的第一個點……

以上牽扯到一個核心的操作邏輯。即CAD的命令欄在你選擇完基礎(chǔ)命令后一步步指引你進行操作，給你提供多種選擇。

即使你對這個命令不熟悉，通過命令欄的提示你也能很快理解。例如剛才舉的例子畫線段，我們都知道兩點確定一線段，因此CAD中繪制線段在命令欄中分兩步，分別是確定兩個點的位置。

5、狀態(tài)欄

狀態(tài)欄位于命令欄下方。

前半部分有一個坐標(biāo)點的數(shù)據(jù)，它表示的是十字光標(biāo)在繪圖區(qū)的位置，而它的參照物是CAD繪圖區(qū)的坐標(biāo)原點，如下圖。這里需要注意的是，Z軸的數(shù)字一般是0，因為我們主要是繪制平面上的圖形。

狀態(tài)欄重點在于后半部分的幾個按鈕，掌握它們，你的繪圖效率會得到極大的提高。

1、首先說下捕捉模式和柵格顯示

它們一般搭配使用，捕捉會自動捕捉最近的柵格點，柵格則是體現(xiàn)在繪圖區(qū)會出現(xiàn)柵格網(wǎng)，這兩個按鈕我建議大家關(guān)掉，會對繪圖的視線造成干擾，同時容易使光標(biāo)閃爍。

2、接下來是正交模式

開啟和關(guān)閉它的快捷鍵是鍵盤上的F8，經(jīng)常會用到希望大家記住。

這個模式非常重要。如果你要畫直線，希望直線橫平豎直，即只在XY方向繪制，那么打開正交模式，所有畫出來的線條都會在XY方向。與此相關(guān)的是其后的極軸模式。

就是通常的帶角度的繪圖模式，與正交模式相反。

3、對象捕捉，快捷鍵F3

這個模式可以極大極大極大極大提高繪圖的效率，非常重要！這里先舉個簡單的例子。

當(dāng)你繪制出了一個矩形，想選中的它的一個角點往上畫別的東西，這個時候把對象捕捉模式打開，那么你會發(fā)現(xiàn)，當(dāng)光標(biāo)移動到矩形角點附近時，會在角點上出現(xiàn)一個綠色的小框。

此時如果你要再往上畫個矩形，那么當(dāng)你繪制時，你會發(fā)現(xiàn)矩形的角點自動吸附到了原矩形的角點上。

因此，對象捕捉模式就像一塊磁鐵，它能讓光標(biāo)自動吸附到一些特殊的點位上，不僅僅是端點角點。

這里鼠標(biāo)右鍵單擊對象捕捉，選擇設(shè)置，里面提供了各種各樣的特殊點和延長線等等。這里提醒下大家，千萬別全部打開哦，不然會被各種磁鐵吸來吸去，眼花繚亂反而降低效率。

4、對象捕捉追蹤

設(shè)想你要畫兩條線段，希望它們不僅平行且頭尾對齊，該怎么畫？

如下圖，當(dāng)你開啟對象捕捉追蹤后，在繪制第二條線段的第二個點時，先將光標(biāo)挪到第一條線段的端點上再慢慢往下挪動（不要單擊，只是挪動），此時會出現(xiàn)一條綠色的虛線，它就像一把尺子一樣能幫助你對齊。

這時將光標(biāo)慢慢往下挪，單擊即可繪制出端點對齊的兩條線啦。

掌握繪圖基本規(guī)范

這個包括標(biāo)注樣式、詳圖、剖圖、引線規(guī)范等。這就像學(xué)會了寫字，組詞造句一樣。

基本要求

制圖技巧

一、圖層管理

1、一般制圖分層

A、墻體層(WALL)；B、家具層(FURNITURE);C、填充層;D、窗層(WINDOW)；E、布置層;F、尺寸層(DIM)；G、文字層(TEXT);H、軸線層(DOTE)；軸線標(biāo)注層(AXIS);J、分格層

制圖時分清各層便于調(diào)整圖紙，節(jié)省時間。

2、線條分色

制圖時將墻體、家具、填充線、文字、分格線等線條顏色區(qū)分，便于在電腦顯示時一目了然。

3、圖框插入

按比例插入圖框

首先制作1:1圖框，將圖框放大，與圖比較看是否配合。如不配合縮放與之配合。如要作1:30的圖框，第一次圖框放大40后不合適，再次縮放輸入3/4，即可得到1:30的圖框B。

二、其他

1、CAD文件在從其他文件粘貼進來后，容易出現(xiàn)無用圖層，可purge(pu)，清理無用圖層。

2、文字的大小是根據(jù)圖紙的比例變化的，如A3圖紙，比例為1:50，注釋文字打印出的尺寸應(yīng)該是3mm，在文字制作時，文字尺寸大小輸入150。

3、一套圖中可能會有不同的比例，在按比例插完第一個圖框后，遇到不同比例的圖，應(yīng)根據(jù)比例的大小縮放。如有一張圖比例為1:50，是正確的，現(xiàn)在要給另一張圖插圖框，假設(shè)這張圖要插1:40的圖框那就復(fù)制1:50的圖框，然后縮放輸入4/5即得。文字的大小亦可采用這種辦法。

4、同一個CAD界面下，如果打開多個CAD文件，可按著ctrl鍵點Tab鍵轉(zhuǎn)換，浩辰CAD等可以直接在文件標(biāo)簽欄點文件名進行切換，最新的ACAD2014也加入了類似的功能。

5、在多重復(fù)制同一個物體時，可將這一物體作成圖塊，如果修改了任意一個圖塊參照，則其他同名圖塊也隨之改變，如不建立圖塊，則每個都需要修改。

6、建立CAD文件時要有選擇的將平面圖、立面圖、詳圖分為幾個文件。

7、最好不要將圖形都花在0層上，0層主要用來定義圖塊。定義圖塊時，先將所有圖元均設(shè)置為0層（有特殊時除外），然后再定義塊，這樣，在插入塊時，插入時是哪個層，塊就是那個層了。

8、不能在DEFPOINTS層建立圖元，此層默認(rèn)是不打印的，在圖層上的圖形會打印不出來。

9、在CAD軟件的使用過程中，雖然一直說是畫圖，但實際上大部分都是在編輯圖。因為編輯圖元可以大量減少繪制圖元不準(zhǔn)確的幾率，并且可以在一定程度上提高效率。

10、在使用繪圖命令時，一定要設(shè)置捕捉，F(xiàn)3切換。

11、在使用繪圖和編輯命令時，大部分情況下，都要采用正交模式，F(xiàn)8切換。

12、圖紙大?。篈0—1194*840；A1—840*597；A2—597*420；A3—420*297；A4—297*210。

13、將CAD文件轉(zhuǎn)化成位圖文件：

第一種是在CAD的菜單中，選擇“輸出”，再選擇bmp的后綴存儲，可以把CAD的屏幕顯示內(nèi)容變成位圖文件，但文件分辨率太小。

第二種是將CAD文件轉(zhuǎn)化成為較大分辨率的位圖文件。添加一個光柵圖像如JPG、TGA、PNG等格式的虛擬打印機。

14、將EXCEL表格倒入CAD可以利用AutoXlsTable插件或是先將EXCEL表格復(fù)制，到CAD里的下拉編輯菜單的選擇性粘貼即可得，到CAD后將表格炸開后即可CAD修改。

實戰(zhàn)演練圖紙設(shè)計

新手在學(xué)習(xí)CAD的時候，光掌握了CAD制圖方法是不行的，還要勤于練習(xí)才行。找一些基礎(chǔ)的練習(xí)圖紙。

小白必備圖紙

剛開始接觸到CAD的小白，肯定不能上來就直接拿一些復(fù)雜結(jié)構(gòu)圖紙讓他們練習(xí)，做任何事都要循序漸進。下面這幾張圖紙涵蓋了CAD機械建筑練習(xí)圖，以及房屋建筑類的練習(xí)圖，是CAD小白必備的練習(xí)圖紙。

基礎(chǔ)練習(xí)圖紙

基礎(chǔ)的練習(xí)圖紙，內(nèi)容是由簡單到復(fù)雜，由平面圖形再到立體圖形的繪制，可以逐步提升繪圖能力，特別適合CAD初學(xué)者練習(xí)使用，下面放出部分的圖紙供大家參考。

注意事項

1、學(xué)習(xí)CAD不要急于求成

CAD的學(xué)習(xí)過程講究循序漸進，先了解繪圖的基本知識，打好基礎(chǔ)，再勤加練習(xí)，知識的吸收要由淺及深，由簡到繁，這樣學(xué)習(xí)起來不吃力，學(xué)習(xí)的興趣也會大一點。

2、不要不遵循作圖步驟

在進行CAD繪圖的時候最好首先要設(shè)置好圖幅大小，然后設(shè)置單位和精度，根據(jù)繪圖對象建立好圖層，設(shè)置好對象樣式后才開始繪圖。

3、繪圖比例亂設(shè)置

在進行繪圖的時候不要自己隨心所欲的設(shè)置繪圖比例，CAD繪圖比例有很多，而每個比例都是科學(xué)設(shè)置的，最佳繪圖比例是1:1，將繪圖比例設(shè)置為1:1絕對不會錯。

4、不要在0層上繪圖

這一點是一定要注意的，因為0層是系統(tǒng)默認(rèn)的圖層，不能更名和刪除，通常用作草稿圖層或插入塊，將圖畫在0層上容易導(dǎo)致圖層混亂，不利于分層管理。5、不要把圖框和圖形畫在同一副圖中

繪圖時如果需要運用到圖框應(yīng)當(dāng)將圖框以塊的形式插入進圖中，而不是直接畫，直接畫在后面打印圖紙的時候容易出現(xiàn)錯亂。

6、遇到問題不及時弄清楚

在繪圖時因為操作的原因可能會出現(xiàn)很多問題，遇到問題一定要第一時間搞清楚，因為你記著記著可能就忘了。比如說畫一張圖，別人畫的大小適中，而你畫起來圖形很小，有的甚至看不見，這可能是因為你沒有設(shè)置繪圖界限而導(dǎo)致的。

7、不設(shè)置線型比例

沒有設(shè)置線型比例可能會導(dǎo)致你用虛線畫線但畫出來看起來就像是用實線畫的，線型比例在設(shè)置的時候還要根據(jù)圖形的尺寸來，如果圖形尺寸特別小可以將圖形比例設(shè)大一點，如果圖形尺寸特別大可以將圖形比例設(shè)小一點。

8、不標(biāo)注工程信息

工程標(biāo)注是工程的重要依據(jù)。在一幅工程圖中工程標(biāo)注是不可少的重要部分。在某些情況下，工程標(biāo)注甚至比圖形更重要。所以小伙伴們在繪圖的時候一定不要忘了標(biāo)注。

9、文字字體不規(guī)范
