ENGT 122 – CAD I

1. ENGT 122 – CAD I Title Blocks & Templates PLUS Chapter 7 – Controlling Drawing Display & Creating Text

2. Title Blocks • Assignment 9 requires you to make A-size and B-size title blocks. • A-Size for A-size sheets (8½x11). • B-Size for B-size sheets (11x17). • The dimensions for lines and text should be as specified on the handouts. • Text style should use an Arial font (you will soon learn what this means).

3. Title Blocks • The title block elements should be arranged on separate layers which can be identified as title block elements. Example:

4. Title Blocks Elements Edge of Sheet *NOTE: All text should be capitalized Border(.7 mm) Assignment # goes here. Problem # or Exercise # goes here. Sheet size (A, B, etc)

5. Title Blocks & Templates • You should save a copy of each title block in a safe place in your home folder. • You can also create templates from copies of each title block file. • When you need to create several drawings that use the same conventions and default settings, you can save time by creating a template file instead of specifying the conventions and default settings each time you start a new drawing. • Read your text Chapter 30 (pp 30-1 thru 30-14) for information on template file creation and use.

6. Title Blocks & Templates Conventions & settings commonly stored in template files : • Unit type and precision • Title blocks, borders, and logos • Layer definitions • Snap, Grid, and Ortho settings • Running OSNAP settings • Dimension styles • Text styles • Etc.

7. Title Blocks & Templates Template Matrix : • It is common to have several template files for various purposes based on sheet size and units. • A typical matrix of templates could include; • A-size sheet with English units • A-size sheet with Metric units • B-size sheet with English units • B-size sheet with Metric units • English vs. Metric Default Settings • Different linetype file loaded (segment lengths vary) • Different hatch pattern file loaded (hatch size varies) • Different dimension style default values Title blocks for English & Metric drawings are identical

8. Title Blocks & Templates • By default, drawing template files are stored in the AutoCAD template folder, where they are easily accessible. • Template files must have a .dwt extension. • To create a template file: • You can start with the file containing one of your title blocks. Then add standard layers, text styles, Osnap settings, etc. • Save your file using SAVEAS, but first select AutoCAD Drawing Template from File of Type box. • The file will be saved as a template file (.dwt) in the AutoCAD Template folder. Select file type .dwt

9. Title Blocks & Templates • You can use the template file when you start a new drawing, and all the information stored in the file (title, block, layers, etc.) will be available. To use your drawing Template File; • Start a new drawing using File > New • Select the Use a Template button to display the list of available templates. • Select your template file and click OK. The stored data will be in your drawing. • Once you’ve completed your drawing, save it as a regular .dwg file in your working folder. This button

10. Title Block Scaling • In previous assignments a rectangular border was scaled up or down to determine the plot scale. Your title block should be used in the same manner. • For an A-size sheet, the A-size title block template should be used. For a B-size sheet, the B-size title block template should be used. • Use the SCALE command to scale your title block (including border) by the inverse of the anticipated plot scale factor. Examples: If an A-size sheet will be used and the plot scale factor is 1:4, the title block should be scaled by a factor of 4 prior to creating the drawing. Then when plotted at 1:4, the title block dimensions on paper will match those in your title block handouts and assignment sheet.

11. Title Block Scaling • Another example: Examples: If a B-size sheet will be used and the plot scale factor is 2:1, the title block should be scaled by a factor of ½ prior to creating the drawing. Then when plotted at 2:1, the title block dimensions on paper will match those in your title block handouts and assignment sheet. • If the scale factor is 1:1, the title block should not be scaled.

12. Alternative - Title Blocks • The title blocks specified on the assignment sheet are required. However, you may create and use an alternative title block similar to that shown which provides more drawing area. • If you choose to create an alternative style as well, it should be laid out according to the following files located in; Outbox\1st Year Students\CAD I\Handouts\ • Alt-A1-Construct.wmf • Alt-B1-Construct.wmf

14. Chapter 7 – Controlling Drawing Display & Creating Text

15. Display Commands • Redraw Command – redraws the screen and removes Blip marks and other remnants caused by modifying geometry. • Command:REDRAW • DDMenu:View>Redraw • Regen Command – redraws the screen like REDRAW, but completely recalculates all objects. • Command:REGENALL • DDMenu:View>Regen All

16. Creating Text Two primary commands for creating text: • Single Line Text Command:TEXT • Multi-Line Text Command:MTEXT • Both text methods can also be accessed through the DRAW drop down menu.

17. Single Line Text • Single Line Text  use TEXT command. • Single Line Text is a misnomer – allows multiple text lines with single command, but each line is a separate object. • Requires the following inputs (but other options available); • Start Point – this is the text insertion point. Pick a location or enter coordinates from keyboard. • Text Height – press [Enter] to accept default or give height by entering a value or using mouse pick (height defined by distance from start point to height pick point). • Rotation angle – text can be angled. Enter an angle value by entering a value (pos. =  from x-axis) or using mouse pick (angle defined by line from start point to pick point). • Text - Enter text to display.

18. Single Line Text • Once Start Point, Text Height, and Rotation Angle are input, a line symbol () and box will appear indicating the Start Point, Text Height, and Rotation Angle. • If not what you expected, issue [Esc] to exit command. • Otherwise enter text and issue [Enter]. • Command will remain active so additional lines of text can be entered (*Note – backspace will continue to previous lines). • End command by pressing [Enter] twice.

19. DEMO 1: • Show TEXT command. • Identify Justify and Style Options. • Methods for specifying height. • Methods for specifying rotation. • Multiple line text.

20. Exercise 1: • Use the TEXT command to create the following. • All text having the same color should be made with a single TEXT command. • Text height: red text = 0.25, green text = use a pick point to define height about as shown.

21. Single Line Text Justify Option: • Text you just created was Left Justified (lower left corner of text string was aligned with specified start point). • Justify option allows you to alter this alignment. The alignment determines what part of the text aligns with the start point. Command: Text Current text style: "Standard" Text height: 1.2082 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]: Justify Options

22. Single Line Text Justify Option: • Alignment determines what part of the text aligns with the start point. • Indicated points will correspond with Start Point when that option is selected. Align/Fit/Center/Middle/Right/TL/TC/TR/ML/MC/MR/BL/BC/BR

23. Single Line Text Justify Option: Align/Fit/Center/Middle/Right/TL/TC/TR/ML/MC/MR/BL/BC/BR Examples:

24.  Align  Fit Single Line Text Justify Option: • The Align & Fit options act different than other Justify options. • Align – text height and width are expanded to fill between 2 selected points. Height and width remain proportional. No height specification required. • Fit – similar to Align except Text Height is input. Height and width are not necessarily proportional. Align/Fit/Center/Middle/Right/TL/TC/TR/ML/MC/MR/BL/BC/BR Examples:

25. Single Line Text Justify Option: • A Justify option can be invoked without issuing (J)ustify. Just enter specified letter(s) identifying alignment type when Start Pointprompt appears. Align/Fit/Center/Middle/Right/TL/TC/TR/ML/MC/MR/BL/BC/BR Example: Command: TEXT Current text style: "Standard" Text height: 0.2500 Specify start point of text or [Justify/Style]: BC Specify bottom-center point of text: ….

26. DEMO 2: • Load file Demo2.dwg • Show TEXT command Justify Options. • Justify – Center, Middle, etc. • Justify - Fit • Justify - Align

27. Exercise 2: • Create the colored lines and rectangles using indicated dimensions. • Use Only the TEXT command to create text with the indicated height and position (No moving the text and no extra construction lines).

28. End Lesson 25

29. Single Line Text Style Option: • You probably noticed the ugly, blocky text style which AutoCAD creates…not to worry, we can change this. • The Style option allows you to select another Existing style (a style must first be created using the STYLE command). • A new text style can be entered or a ? will display the available Existing text styles. Command: TEXT Current text style: "Standard" Text height: 0.2000 Specify start point of text or [Justify/Style]: S Enter style name or [?] <Standard>: Enter Name of new Style …

30. Single Line Text Text Style System Variable: • The default text style can be preset using system variable TEXTSTYLE or through the Styles toolbar. • Command: TEXTSTYLE Enter new value for TEXTSTYLE <"Standard">: Provide a Style Name • Styles Toolbar Styles Toolbar

31. Single Line Text Style Command: • Before the Style option can be used, a new text style must be created. Command:STYLE DDMenu:Format > Text Style… • Both methods bring up the Text Style dialog box.

32. DEMO 3A: • Show how to create a new text style. • Command:STYLE • DDMenu:Format > Text Style… • Create a new style • Show Style option in TEXT command.

33. Exercise 3: • Create the text table shown as follows: • Create the first line of text (green) using a style , font, and height of your choice. • Then create 2 additional text styles (shown in red and yellow) as defined in lines 2 and 3. (keep Height = 0.0 when you create the new styles) • Create the text in lines 2 and 3 using the text height and style indicated.

34. Single Line Text STYLE Command: Important points about the STYLE command: • The default height is set to 0.00. If you change this value, you will not be prompted for height when TEXT is issued. • More flexible to leave height set to default 0.00. Text Height: • Standards for text height are based on plotted size= 0.125”. • Plotted text height is affected by the plot scale factor. • To achieve the correct plotted text size, use a text height equal to the desired plotted height multiplied by the inverse of the plot scale factor. Example: To achieve 1/8” plotted text for a plot scaled at 1:4. the text height in AutoCAD should be 1/2”.

35. Single Line Text Text Scaling: • Many times you will need to change the text height before plotting to get the correct plotted text height. The SCALETEXT command accomplishes this. Command: SCALETEXT Select objects: Select desired text Enter a base point option for scaling [Existing/Left/Center/Middle/Right/TL/TC/TR/ML/MC/MR/BL/BC/BR] <Existing>: Existing Start point or select other Specify new height or [Match object/Scale factor] <0.2000>: Enter height or option.

36. DEMO 3B: • Load demo file Demo3B.dwg. • Check existing text height using PROPERTIES. • Find scale factor using border scaling. • Show use of SCALETEXT vs SCALE command for scaling text.

37. Single Line Text Special Characters: • Some common drafting symbols require special characters. Examples: • Diameter symbolØ5.5 %%c • Degrees symbol35º %%d • Plus/Minus±2.21 %%p • UnderscoreUnderscore%%u • Type the control characters as specified to get the indicated symbol. • The underscore symbol %%u acts as a toggle. Place before and after the characters to be underscored. AutoCAD Control Characters

38. DEMO 4: • Show use of special characters in Single Line Text. • Diameter symbolØ5.5 %%c • Degrees symbol35º %%d • Plus/Minus±2.21 %%p • UnderscoreUnderscore%%u • Percentsign% %%%

39. Exercise 4: • Create the following text which includes special characters. Use the height and angle specified if indicated. • For Reference Only: • Ø5.5 %%c • 35º %%d • ±2.21 %%p • Underscore%%u • % %%%

40. End Lesson 26

41. Multiline Text Multi-Line Text -MTEXTcommand: • Multi-Line Text should actually be called paragraph text. • Many of the same functions as TEXT command, just implemented in a different way. • The text object created by MTEXT is a single object regardless of the number of text lines. For single line text (TEXT), each line is a separate object. • Allows more formatting options than for TEXT.

42. Multiline Text • Creating Multiline Text • Command:MTEXT • Draw Toolbar Menu: • DDMenu:Draw > Text > Multiline Text • All methods activate the Multiline Text Editor.

43. Multiline Text • Multiline Text Editor Consists of 2 Parts: • Text Formatting Box • Sets the general text style. • Sets the font for individual letters or words. • Sets general text height. • Allows formatting and color changes. • Text Box • Width of ruler indicates location for text wrap.

44. DEMO 5: • Load file Demo 5.dwg. • Show MTEXT Command. • Text Style • Separate Fonts • Text Height • Color • Tabs and Paragraph Format • Expanding width (drag ruler)

45. Exercise 5: • Create a new text style called Ex5 using the Sans Serif font and a default text height of zero (0). • Use MTEXT and type the entire text using text style Ex5. • Then apply text formatting to modify the text EXACTLY as shown. The “wrap” location and paragraph formatting can be applied when you are nearly finished.

46. Multiline Text Multiline Text - Additional Items • Stacked Characters – for some special effects StackedCharacters are required. • Text is separated by a special character and converted to stacked characters using the STACK button.

47. DEMO 6: • Demonstrate Stacked characters. • Show PROPERTIES for stacked characters.

48. Exercise 6: • Recreate the table below using MTEXT and stacked characters. • Tab inserts may be useful. • Use the following data: • Font = Arial • Text height = 0.125”

49. Multiline Text Multiline Text Additional Items Right clicking in the text box displays a shortcut menu with several additional useful options

50. DEMO 7: • Demonstrate Shortcut Menu. • Copy & Paste • Change Case • Symbol • Must have Cap Locks and AutoCaps off • Import Text (Demo7.txt)
