1. Copylink, Pasteclip

Open the CH22EX1-M drawing from the Chapter 22 exercises. Use Copylink to copy the entiredrawing to the Windows clipboard. Start WordPad and type the following sentence: Identifyeach type of bolt in the following figure below. Use Pasteclip to insert the contents of the clip-board into WordPad. Save the WordPad file as CH31EX1-M.DOC.

2. Copyclip, Pasteclip

In this exercise you will create a cover sheet and insert general notes onto the sheet. Begin aNew drawing and set Limits for a C-Size sheet. Create orInserta border and titleblock.While AutoCAD is running, start WordPad and type the paragraph of notes as shown below.

1. INTERPRET DIMENSIONS AND TOLERANCES PER ANSI Y14.5M-1994.2. UNLESS OTHERWISE SPECIFIED, ALL DIMENSIONS ARE IN MILLIMETERS.3. REMOVE ALL BURRS AND SHARP EDGES.4. ALL FILLETS AND ROUNDS R5.5. CASE HARDEN 62 ROCKWELL C SCALE.6. FINISH BLACK OXIDE.7. PART TO BE CLEAN AND FREE OF FOREIGN DEBRIS.

Next, select all ofthe text and use theCopy command

(Copy from the Editpull-down menu) tocopy the text fromWordPad to the clip-board. Return to thenew AutoCAD draw-ing and use Pasteclipto insert the text asshown in FigureME31-1. You mayneed to resize thetext box to generateappropriately sizedtext. Savethe drawing asCH31EX2-M.

3. Editing an Embedded Object

Open the CH31EX2-M drawing from the previous exercise. Double-click on the text block toopen the text back in the original WordPad program. Change the size of the fonts and make allof the text bold. Exit WordPad. Note that the changes are automatically updated in AutoCAD.SaveAs CH31EX3-M.

4. Copyclip, Pasteorig

Open drawing CH28EX2-M from the Chapter 28 exercises. Use Copyclip and select all objectsto copy to the Windows clipboard. While this drawing is open, begin aNew drawing. UsePasteorigto paste the objects into the new drawing. Use Saveas and assign the nameCH31EX4-M to the new drawing.

If you compare the two open drawings (use the

Window pull-down menu or press Ctrl+Alt), youmay notice that the dimensions appear differentlysince the new drawing does not have a previouslycreated dimension style or appropriate dimensionvariable settings. To remedy this you can performone of the following actions:

A. Use DesignCenter to drag and drop the dimen-sions style from the CH28EX2-M drawing intothe CH31EX4-M drawing, make the newdimension style current, then Update the exist-ing dimensions.

B. Create a new dimension style with the appro-priate settings, then Update the existingdimensions.

When you are satisfied that the two drawings lookthe same, Erase the diameter dimensions in theCH31EX4-M drawing and replace them with labels A, B, and C as shown in Figure ME31-2.

Next, while AutoCAD is running, open Word and construct the following table:



Figure ME31-2

When finished, use Copy from the Editpull-down menu (in Word) to copy the table to theWindows clipboard. Go to your AutoCAD drawing and use Paste to bring the table into theCH31EX4-M drawing. Highlight the table and reposition and resize the table appropriately.(Alternately, right-click on the highlighted table and select Properties from the menu to pro-duce the OLE Properties dialog box. Experiment with the Size and Scale to achieve the desiredarrangement.) In the OLE Properties dialog box, set the Plot Quality to Line Artto achieve ahigh quality print. Save the drawing and make a print.
