Quiz: April 6, 2015

3. Drawing Commands
Style- sets the font, size, angle, orientation, and other text characterizations. The Text Style dialog box is displayed.
You can specify the current text style to determine the appearance of all new text. A text style includes the font, size, obliquing angle, orientation, and other text characteristics.

4. Drawing Commands
Dimstyle- Creates and modifies dimension styles. The Dimension Style Manager is displayed.
A dimension style is a named collection of dimension settings that control the appearance of dimensions. You create dimension styles to specify the format of dimensions quickly, and to ensure that dimensions conform to standards

5. Editing Commands
SCALETEXT-Enlarges or reduces selected text objects without changing their locations. Select Objects: Specified the text you want to scale. Base point option for scaling: Specified the location to serve as a base point for resizing or scaling. New model height-Specifies a text height

6. Editing Commands
JUSTIFYTEXT-Changes the justification point of selected text objects without changing their locations. The justification point options shown above are described in the TEXT command. The justification point options for single line text are similar to those for multiline text except that the Align, Fit, and Left text options are equivalent to the bottom left (BL) multiline text attachment point. Select objects: Specified which text you want to modify. Enter a justification option: Specifies the location of the justify text (Left, Align, Fit, Center…)

7. Display Commands
QTEXT-Controls the display and plotting of text and attribute objects. When QTEXT (Quick Text) is turned on, each text and attribute object is displayed as a bounding box around the text object. Turning QTEXT mode on reduces the time it takes to regenerate drawings that contain many text objects. Use the REGEN command to display the results of QTEXT on existing text

8. Data Management
Block- Creates a block definition from selected objects. The Block Definition dialog box is displayed.
If you enter -BLOCK at the Command prompt, options are displayed.
You create a block definition by selecting objects, specifying an insertion point, and giving it a name.

9. Data Management
Wblock-Saves selected objects or converts a block to a specified drawing file. The Write Block dialog box is displayed.
Entering -wblock at the Command prompt displays a standard file selection dialog box in which to specify a name for the new drawing file, followed by command prompts. If FILEDIA is set to 0, the standard file selection dialog box is suppressed.

10. Data Management
Insert-Inserts a block or drawing into the current drawing. The Insert dialog box is displayed.
If you enter -INSERT at the Command prompt, options are displayed.
A good practice is to insert a block from a block library. A block library can be a drawing file that stores related block definitions or it can be a folder that contains related drawing files, each of which can be inserted as a block. With either method, blocks are standardized and accessible to multiple users.
You can insert your own blocks or use the blocks provided in the DesignCenter or tool palettes

11. Data Management
MINSERT-Inserts multiple instances of a block in a rectangular array. Options at the insertion point preset the scale and rotation of a block before you specify its position. Presetting is useful for dragging a block using a scale factor and a rotation other than 1 or 0. If you enter one of the options, respond to the prompts by specifying a distance for the scale options or an angle for rotation.
Blocks inserted using MINSERT cannot be exploded.
You cannot use MINSERT with annotative blocks.

12. Dimension Variables
Dimse1- Suppresses display of the first extension line
Dimse2- Suppresses display of the second extension line
Dimsd1-Controls suppression of the first dimension line and arrowhead
Dimsd2-Controls suppression of the second dimension line and arrowhead.
Dimtih- Controls the position of dimension text inside the extension lines for all dimension types except Ordinate.
Dimtoh-Controls the position of dimension text outside the extension lines.
Dimtix- Draws text between extension lines.
