There are at least five commands devoted to duplicating objects, ten if you include the Grips options. Why so many? If you’re an experienced drafter, you know that technical drawing is often tedious. So AutoCAD offers a varictv of ways to reuse existing geometry, thereby automating much of the repetitious work usually associated with manual drafting.
In this chapter, as you finish drawing the studio apartment unit, you will explore some of the ways to exploit existing files and objects while constructing your drawing. For example, you will use existing files as prototypes for new files, eliminating the need to set up layers, scales, and sheet sizes for similar drawings. With AutoCi\D you can also duplicate objects in multiple arrays. You have already seen how to use the Osnap overrides on objects to locate points for drawing complex forms. This chapter describes other ways of using lines to aid your drawing. And, because you will begin to use the Zoom command more in the exercises of this chapter, you will review this command as you go along. You’ll also discover the Pan command-another tool to help you get around in your drawing. You’re already familiar with many of the commands you will use to draw the apartment unit. So, rather than going through every step of the drawing process, the exersises will sometimes ask you to copy the drawing from a figure, using notes and dimensions as guides and putting objects on the indicated layers. If you have trouble remembering a command you’ve already learned, just go back and review the appropriate section of the book.
Creating and Using Templates
If you are familiar with the Microsoft Office suite, you are probably familiar with templates. A template is a blank file that is already set up for a specific application. For example, you might want to have letters set up in a way that is different from a report or invoice. You can have a template for each type of document, each set up for the needs of that document. That way, you don’t have to spend time reformatting each new document you create.
Similarly, AutoCAD offers templates, which are drawing files that contain custom’ ignored for a particular function. Out of the box, AutoCAD offers templates for bO, ANSI, DIN, and JIS standard drawing formats. But you aren’t limited to these “canned” templates. You can create your own templates sat up for your particular style and method of drawing
If you find that you use a particular drawing setup frequently, you can turn one or more of your typical drawings into a template. For example, you may want to create a set o’drawings with the same scale and sheet size as an existing drawing. By turning a typical drawing into a template, you can save a lot of setup time for subsequent drawings.
Creating a Template
The followin exercis~uides) au through creating and using a template drawing for your studio’s kitchenette. Because the kitchenette will use the same layers, settings, scale, and sheet size as the bathroom drawing, you can use the Bath file as a prototype.
1. Start AutoCAD in the usual way.
2. Click File Open.
3. In the Select File dialog box, locate the Bath file you created in the last chapter. You can also use the file 04c-bath. dwgfrom the companion CD-ROM .
4. Click the Erase button on the Modify toolbar; then type all.Li. This crases all the objects that make up the bathroom.
5 Choose Fill>. Save As. Then in the Save Drawing As dialog box, open the Save as Type drop-down list and select Drawing Template File (*,dwt). The file list window changes to display the current template files in the Temp1ate\ folder.
6. Douhle-chck the filename input box and enter the name 8×11. If vou’re a metric user, save the drawing; as A4plan.
7. Click Save. The Template Description dialog box appears
8. Enter the following description: Architectural One inch scale drawing on 8 1/2 by 11 inch media. Metric users should enter the description: Architectural1: 10 scale drawing on A4 media.
9 Select English or Metric from the Measurement drop-down list, depending on the unit system you’re using.
10 Click OK. You have just created template.
11 Close the current file without saving it. You don’t want to save this file with the objects deleted..
11. Notice that the current drawing is now the template file you just saved. As with other Wmdows programs, theFile >- Save As option makes the saved file current. This also shows that you can edit template files just as you would regular drawing files.
Using a Template
Now let’s see how a template is used. You’ll use the template you just created as the basis for a new drawing you will work on in this chapter.
1. Choose File New.
2. In the Create New Drawing dialog box, click the Use a Template button. A list box entitled Select a Template appears, along with a Preview. window.
3 Click the filename 8xllh. dwt from the Select a Template list box. Metric users should click the filename A4p 1an . dwt. The file is displayed in the Preview window. Since it is a blank file, you won’t see anything in the Preview window. Notice that the description you entered earlier in the Template Description dialog box appears in the Template Description area below the list
4. Click OK. It may not be obvious, but your new file is set up with the same architectural units and drawing limits as the bathroom drawing. It also contains the Door, Toilet, and Tub blocks.
5 Now .you need to give your new file a name. Choose File >Save As. Then in the Save Drawing As dialog box, enter Kitchen for the filename and select the appropriate folder in which to save your new kitchen file.
6 Click Save to create the Kitchen file and close the dialog box
You’ve created and used your own template file. Later, when you have established a comfortable working relationship with AutoCAD, you can create a set of templates that are custom made to your particular needs.
However, you don’t need to create a template every time you want to reuse setings from another file. You can use an existing file as the basis or prototype for a new file without creating a template. Open the prototype file and then use File Save As to create a new version of the file under a new name. You can then edit the new version without affecting the original prototype file.
