    Abstract. The article is about how to paste the drawing designed by using AutoCAD into PowerPoint, and to show the drawing process in two different forms of animation by examples. By compari-ng the two different forms of animation, it advances more practical methods and skills for animati-on, and for others ' reference.

    Introduction

    Multimedia courseware has gradually spread to various industries nowadays, its benefits have long

    been accepted. It sets characters, animation and sound in one, to bring a kind of visual and auditory e

    njoyment. Multimedia courseware in teaching also plays an increasing role, particularly the teachi-ng

    of engineering drawing, due to the abstract content. When you use the multimedia coursewarein t

    eaching to achieve better teaching efficacy, courseware quality is essential. If drawing steps canbe

    displayed with animation step by step, teaching effect will be more ideal. The animation effectwo

    nt be good enough with patterns which are scanned or are pictures taken by camera. But if patt-ern

    is drawn in AutoCAD drawing software, and is pasted to PowerPoint software, it can be madeinto

    an ideal courseware with perfect effect. In the light of my experience for years, I summarizetwo

    methods of making animation to peers for reference.

    Ungroup method

    Paste the patterns drawn in AutoCAD to PowerPoint slide show, and then you can make anima-t

    ion of drawing process by ungroup method. As is shown in Figure 1, three axonometric drawingo

    f the step, make three projections of the assembly. Analyse the assembly first, this assembly can beth

    ought as two cuboids, A and B, consisted of, and the back surface of the two cuboids are at thesa

    me level. When drawing three projections of the assembly, we should draw three projectionsof

    cuboid A using thin solid lines, according to the shape analysis and the arrow direction of thesele

    cted front projection. As is shown in Figure 2, and then on the basis of the projection ofcubo

    id A, draw the projection of the second cuboid on three sides. As is shown in Figure 3.Final

    ly arrange and deepen, and finish the whole picture. As is shown in Figure 4.

    Above is the drawing process of the assembly projection by shape analysis method. How thed

    rawing process reflected in the slide? This requires making every step of the drawing process intoan

    imation to reflect the drawing process. The method is zooming the pattern in the Figure 3 to a rig

    htsize in AutoCAD interface, left click Copy Link under Edit, and then open the PowerPoint,rig

    htclick to paste the pattern to the slide, and picture pasted. Right click the picture and choos-e t

    he picture toolbar, cut off the extra white space around the picture. Then pull the picture into an app

    ropriate size, left click it, then right click Ungroup. Repeatedly click until the word dim.Now

    the pattern is shown as Figure 5.

    Click on the slide show to display. Left click, the three projections of cuboid A will be shown,

    and left click again, the three projections of cuboid B will be shown. So animation effect comes out.

    mn in Figure 3 is an extra line due to the shape analysis method and should be deleted. Here is t

    he method. Left click the line which has been copied, and right click Set the Selected Picture Form

    at dialog box. Choose white as spline color. Choose 3 pounds or other thicker line width as its

    style. As the case may be. As is shown in Figure 6. And then pull the line to m n position, andt

    he line completely coincide with the line mn. If not, right click the line to edit the apex to coinci-d

    e. And now the line mn is covered with this white line. At the end of the show, the final drawingis

    shown as Figure 7. Finally the final pattern after deepen can be drawn in AutoCAD, and thenbe

    copied and linked to a new slide show, draw the custom animation directly.

    Multiple pictures overlapping method

    Multiple pictures overlapping method, is dividing the drawing process into many pictures of thes

    ame size. Each picture stands for a kind of drawing process. A picture always hides the one behindit,

    and the last picture is the final result. Also, we will demonstrate the making method of animationby

    steps mentioned above. Make patterns in Figure 2 into appropriate size in CAD, and then clickon t

    he down restore button in the upper right corner of the AutoCAD interface. The interface beco-mes

    smaller. And then make the pattern in Figure 2 into a suitable size that fulfills this smaller interf

    ace. Then click on the copy link, after right clicking to paste in the PowerPoint slide, you canmake

    custom animation, and drag the picture to the lower right corner of the slide. Open the Auto-CAD i

    nterface which has been reduced and keep it stay. On the basis of the first step picture, drawthree pr

    ojections of the cuboid B. When it is finished, copy and link. Right click to paste the customanimati

    on in the former slide, drag the picture to the lower right corner of the slide, and picturesare comp

    letely overlapped. mn is a line in the process of drawing, so they need to be deleted.Turn m

    n into red in that AutoCAD interface, and then copy link to the former slide. Right clickon the pi

    cture and choose Set the Picture Format dialog box, in the dialog box, click on the pictureand choos

    e Recolor, change red into white, and drag this picture to the lower right corner of theslide, mak

    e it completely overlapped with the former two pictures. At last, put the finished rightpattern to t

    hat slide in AutoCAD, the method is the same as mentioned earlier. There are 4 picturesin total. In t

  • he lower right corner of the slide area, left click and drag toward upper right to selectthese 4 pictu

    res, then four pictures will be selected at the same time. You can drag this picture free-ly with the le

    ft button, you can be free to widen or narrow, 4 pictures are corresponding all the time.After you clic

    k on the show, on the first click, three projections of cuboid A appears, on the second click, appears

    cuboid B, on the third click, appears the animation process of deleting mn, on theforth click, the

    final pattern occurs. Every time you click on the mouse, the animation appears. Youcan see each ste

    p of the drawing process. Animation effects comes out. In fact, the second picturecontains the cont

    ent of the first picture. the third picture contains the second picture, the forthpicture contains t

    he third picture. But in the show, the animation of two adjoining pictures cant beshown because th

    ey are overlapped, and only the new line animation can be shown. Say, when dis-playing the second

    picture, it seems that only three projections of cuboid B can be seen, as a matterof fact, there is ani

    mation of three projections of cuboid A in the second click, too. The reason thatyou cant see it is th

    at the two same pictures are overlapped. Finishing the slide show, the finalresult is shown as Fig

    ure 4.

    Comparison of two animation methods

    Compare the two methods of the animation, the effect is excellent, but the production process

    has advantages and disadvantages. You can paste the complete pattern to the slide for one time withu

    ngroup method, and then make custom animation, this method is more convenient for simplepat

    terns, but for complex patterns, when making custom animation, order, it is easy to confuse. Younee

    d to draw step by step with multiple pictures overlapping method, first draw, and then paste, fin-ally

    make custom animation, the process is tedious, but the animation production process is alwaysgoing

    on without errors. Compare the two methods, multiple pictures overlapping method is moreconve

    nient, despite the complex drawing process, the order wont be confused.I suggest that youdbetter

    use the second method when making courseware, I am using this method to make coursewareat pres

    ent, the effect is perfect.
