1. ENGT 122 – CAD I Chapter 6 – Editing With Grips

2. Get a Grip! What are Grips? • Small squares displayed on an object at its definition points when selected by the mouse. • Quick and easy way to edit objects. • Number and location of grips depends on object selected. • Allows object editing as following; Stretch Move Copy Mirror RotateScaleChange Properties

3. Hover Grip Status Grip Status Classification; • Cold – not displayed • object not selected • object not highlighted • grip can be snapped to • Warm – displayed in blue • select object • object highlights • Hot – displayed in red • select object • object highlights • grip selected • object can be edited • Hover – displayed in green • object selected • object highlighted • When mouse hovers over grip of selected object.

4. General Editing General Procedures for Editing with Grips: • Select object to edit with mouse. • Object will highlight • Grips will appear blue (warm) • Hover over desired grip. Grip will turn green when mouse is properly positioned to acquire grip. • Acquire the grip or grips required for the edit (left mouse click). Use [Shift] to acquire multiple grips. • Object remains highlighted • Selected grips will turn red (hot) • Perform the edit.

5. General Editing General Procedures for Editing with Grips: • Multiple grips selected by depressing [Shift] key during grip selection. • Number of grips selected affects outcome of edit. • Particular grip selected also affects edit result. 1 Grip Selected 3 Grips Selected

6. Grips - Stretch STRETCHMode – default mode for grip editing. • Similar to STRETCH command, but allows Copy option. • One or more grips can be selected – Unselected grips remain stationary, selected grips are moved. Geometry between selected and unselected grips is stretched. • To select multiple grips, the [Shift] key must be depressed during selection. • After grip selection, a base point grip is selected from displayed grips (blue or red), and command line responds; Command: ** STRETCH ** Specify stretch point or [Base point/Copy/Undo/eXit]:

7. Grips - Stretch Command: ** STRETCH ** Specify stretch point or [Base point/Copy/Undo/eXit]: • Stretch point - pick point and base grip stretches to new point. • Copy – makes copies of stretched portions of object. • Base Point – allows selction of any point (grip, osnap, keyboard entry) as new base point for stretching.

8. Demo: Stretch Mode • Load file Grip_Demo.dwg • Demonstrate Grip Stretch Mode • Stretch with single grip • Stretch with multiple grips • Copy • New base point

13. Grips - Copy COPY Mode - Allows entire object to be Copied. • Method 1: Shortcut Menu • Allows copy & paste options similar to MS Office. Important: this method can be used to copy objects from one drawing to another! • Select objects to highlight them and right click for shortcut menu. • Select Copy to place copy of objects in buffer. • Select Paste to paste objects from buffer. • Copy with Base Point allows insertion point to be selected for better control.

14. Grips - Copy COPY Mode - Allows entire object to be copied. • Method 2: QuickDragCopy • Select objects to highlight them. • Reselect object with left mouse and hold (not on grip), depress [Ctrl] key and drag to new location.

15. Grips - Copy COPY Mode - Allows entire object to be copied. • Method 3: Copy Selection - Identical toCOPY command • Select objects to highlight them. • Right click for shortcut menu and choose Copy Selection. • Pick a base point and then choose 2nd point for displacement. • Multiple copy is enabled.

16. Demo: Copy Mode • Load file Grip_Demo.dwg • Demonstrate Grip Copy Mode • Shortcut Menu • Quick Drag Copy • Copy Selection

17. Exercise 2: • Create a rectangle and circle as shown in blue below. • Use grips with the Copy Selection option to create the pink rectangles using a single edit. • Use grips with the Copy with Base Point and Paste options to create the pink circles. X X

18. End Lesson 23

19. Grips - Rotate ROTATE Mode - Allows entire object to be rotated. • Method 1: Shortcut Menu - Identical toROTATEcommand • Select object to highlight it. • Select ROTATE from shortcut menu. • Select base point and enter angle or Reference option. • Method 2: Rotate with Multiple Copy • Select object to highlight it. • Pre-select base point by selecting base grip. • Select ROTATE from shortcut menu. • Select COPY from shortcut menu. • Enter angle or rotate option consecutively for each rotated copy desired.

20. Demo: Rotate Mode • Load file Grip_Demo.dwg • Demonstrate Grip Rotate Mode • Shortcut Menu • Rotate with Multiple Copy

21. Exercise 3: • Create a line and circle as shown in blue below. • Use grips with the ROTATE and COPY options to create multiple rotated copies in a single operation as shown.

22. Grips – Other Options • Grips can also be used to: • Mirror objects • Scale objects • These options are accessible through the shortcut menu. • These are less commonly used and won’t be discussed. • You can experiment on your own if interested.

23. Grips - Properties Properties Command • Grips allow properties of an object to be modified. • Select object to display grips. • Select PROPERTIES from the shortcut menu. • Other Methods: • Command: PROPERTIES • Toolbar menu (toggles on/off).

24. Grips - Properties • The control buttons on the Properties and Layers tool bars can also be used to modify properties of selected objects. Layer ControlColor Control Linetype ControlLine Weight Control • Select objects to display their grips. • Select control button item and objects will inherit those properties. Example: select objects then select a color from Color Control. Selected objects will inherit that color, but remain on their original layers.

25. Demo: Properties • Load file Grip_Demo.dwg • Demonstrate changing properties. • PROPERTIES on shortcut menu. • Transfer properties using Properties Toolbar. • Show single object selection • Show multiple object selection • Show BYLAYER vs by property
