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.

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: 10.0000 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]:

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.

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 36.85 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%

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.

4. Setting Dimension Style First, creates, modifies, or sets named text styles for dimensioning

Modify Dimension Style by National Standard GB Click modify

Dimension Types Linear Aligned Arc Ordinate Radius jogged radius dimensions Jogged ordinate point dimensions Diameter Angular Quick Dimension Baseline Continue Leader Tolerance Center Mark Dimension Edit Dimension Text Edit Dimension Update Continued dimensions Dimension Style a leader and leader annotation

5. Dimensioning Symbols for Draws (1)Dimensioning limits deviation value: from to Click Dimension edit in Dimension toolbar:

Indication of Fits and Fraction Mark on Drawing Fit Mark: From to Click Dimension edit in Dimension toolbar: Fraction Mark: G 3/4

Indication of Geometric Tolerance Mark on Drawing

6. Defining and using Block Attributes Block name : ccd-up From -89°to +90° Block name : ccd-down From -89°to +90° .

Exercises Three After Class Making your A3 template file including roughness attribute Blocks ,GB text and Dimension Style Creating a Title outside block with Chinese texts (3) Creating a Engineering Drawing
