4. 1. Setting Up Text Style
When you create single-line text and multiline text, you should assign a
text style. Most characteristics of the text are controlled by the text
style, which sets the default font and other options, such as line
spacing, justification, and color. You can use the current text style or
select a new one. The STANDARD text style is the default.

7. 2. Create Single-Line Text
Use single-line text (TEXT) to create one or more lines of text, ending each line when you press ENTER. Each text line is an independent object that you can relocate, reformat, or otherwise modify.
Command: text
Current text style: "GB" Text height:
Specify start point of text or [Justify/Style]: j
Enter an option [Align/Fit/Center/Middle/Right/TL/TC/TR/ML/MC/MR/BL/BC/BR]:

8. Application of single-line Text
Editing single-line text.
Select edited line
Double-click left key
on your mouse.
You can insert or erase
some characters.
Modify single-line text
Selecting modified line
Single-click left key
On your mouse.
You can move, rotate, copy,
Scale the line
Creating a single-line text.
Each line text is a object.

9. Control Codes and Special Characters
you can use overscore text, underscore text, or insert a special character by including control information in the text string. %%o Toggles overscoring on and off. such as %%u Toggles underscoring on and off. such as You can use a pair of percent signs to introduce each control sequence. %%d Draws degrees symbol . 360° %%p Draws plus/minus tolerance symbol . ±25 %%c Draws circle diameter dimensioning symbol . Φ30 %%% Draws a single percent sign (%). 100%

10. 3. Creating Multiline - Text
You can create one or more paragraphs of multiline text (mtext) in the In-Place Text Editor. They are shown as a object when modifying them
Specify first corner:
Specify opposite corner
After you specify the point for the opposite corner, the in-place text editor is displayed.
 You can very easy edit multline-text by pointing device: Double-click a multiline text object.
