一、說明
在用AUTOCAD製圖的過程中，必然要寫說明性文字。當然在製表和寫設計說明時，文字量就更大，AUTOCAD寫文字並無難處，難的是怎麼使寫出的文字的尺寸、間距、對齊等方面象文字處理軟體那樣合適。若用AUTOCAD基本命令來處理，會很麻煩，並影響作圖速度。為此我編寫了一些小程序供大家使用。這次我提供如下兩個程序：
二、程序的安裝及使用
先把ZDDQ．LSP和ZDJT．LSP 拷貝到一個特定的目錄下(如:C:\R12\SUPPORT或C:\TCH\SYS等)。用戶可以將持到AUTOCAD或其它開發軟體的系統菜單上，通過菜單來調動，也可以AUTOCAD環境COMMAND後面用LOAD命令裝入，形成一個附加命令ZDDQ或ZDST。
1．將程序調用裝入系統菜單
先找到菜單源文件ACAD.MNU，並編輯它。在* * * POP1最後加下面內容。
［字的對齊］^C^C^P(“ZDDQ”)；ZDDQ；^P。
［字的間距調整］^C^C^P(LOAD“ZDJT”)；ZDJT；^P。用滑鼠點取下拉菜單即可調用。
2．命令調 用ZDDQ．LSP、ZDJT．LSP
在COMMAND後面輸入(LOAD“ZDDQ”)或(LOAD“ZDJT”)，產生可用命令ZDDQ、ZD JT，擊入命令按提示操作。
3．兩程序在使用中基本為中文提示，易用，現已在我院網路上全面使用。
4．兩程序適用於AUTOCAD R10.0, R11,R12.0。
三、操作過程
1．多文字對齊。提示如下：(其中“<>”中為預設的選項)
選擇對齊方式如下：L左/R右/C中心/M中點<L>：
選擇對齊方向如下：1橫向對齊(Y座標一致). 2縱向對齊(X座標一致) <2>:
點取對齊點<點取參照實體>：(即用滑鼠在屏上點取對齊的位置，預設后，提出讓你點取參照目標字，這樣後面選上的文字與對齊)
選取文字(自動濾非文字類實體，且不用考慮次序，開窗口選也可)。
2．多文字的間距調整，提示如下：
文字間距調整方式如下：
1. 水平 2. 垂直 3. 斜向 <1>：
① 若選“1”或預設值，則
* 輸入各文字水平距值(或用滑鼠點取)
* 選擇對齊方式：(C中心/L左側/R右側/H中心) <L>
1 若選“L”或預設，則：
* 輸入這組文字起點。
* 按選后次序選取文字。
2 其它類推。
選“2”，則：
* 輸入文字垂直間距值(或用滑鼠點取)：
其它同①。
選“3”，則：
* 按先後次序選取文字。
* 點取斜線起點(即文字排列方向線)。
* 點取斜線終點。
(結果所選文字在斜線起點和終點間等分排列)。
