As mentioned briefly in Chapter 3. when using AutoCAD, you first create the most basic forms of your ; then you refine them. In this section you will create drawings the studio apartment unit and the lobby-that demonstrate this process in more detail.
First, you will construct a typical studio apartment unit using the drawings you have created thausand In the process, you will explore the use of lines as reference objects.
You will also further examine how to use existing files as . In Chapter 4, you inserted a into another file. There is no limit to the size or number of files you can insert. As you may already have guessed, you can also nest files and blocks, that is, insert blocks or files within other blocks or files. Nesting can help reduce your drawing time by allowing you to build one block out of smaller blocks. For example, you can insert your door drawing into the bathroom plan. The bathroom plan can in turn be inserted into the studio unit plan, which also contains doors. Finally, the unit plan can be inserted into the overall floor plan for the studio apartment building.

Importing Settings

In this exercise, you will use the Bath file as a prototype for the studio unit plan. However, YOll must make a few changes to it first. Once the changes are made, you will import the bathroom and thereby import the layers and blocks contained in the bathroom file as you go through this exercise, observe how the drawings begin to evolveing simple forms to complex, assembled forms.

1. First, open the Bath file. If you skipped drawing the Bath file in Chapter 4, use the file named 04c-bath. dwg from the companion CD-ROM.
2. Use the Base command and select the upper-left comer of the bathroom as the base point for this drawing, so you can position the Bath file more accurately.
3. Save the Bath file. If you use the file from the CD-ROM, use File :- Save As and save it as Bath.
4. Choose File Close to close the Bath drawing.

Next you will create a new file. But this time, instead of using the Start from  Scratch or Use a Template option in the Create New Drawing dialog box, you’ll try out the Use a Wizard option.

1. Choose File ~ New .
2. In the Create New Drawing dialog box, choose Use a Wizard. Yotr’ll see two options in the Select a Wizard list box. Choose Quick Setup and then click OK. The Quick Setup dialog box appears.

5. Enter 528 in the Width input box and 408 in the Length input box. These are the appropriate dimensions for an 81/2″ x 11″ drawing at 1/4″=1 ‘-0″ scale. Metric users should enter 1485 for the width and 1050 for the length. This is the ‘work area for a 1:50 scale drawing on an A4 sheet.
6. Click Finish.
7. Use Tools > Drafting Settings to set the snap spacing to 1″ and the grid spacing to 48″. This sets the grid spacing to display the equivalent of l-inch intervals for a 1/4″=1’ -0″ scale drawing. Metric users should set the snap spacing to 1 and the grid spacing to 120.

Your drawing is now set up. However, this time, you used the Quick Setup Wizard option to set it up. In fact, the Quick Setup Wizard does nothing more than combine the Format >Units and Format > Drawing Limits options into one dialog box. Now let’s continue by laying out a typical studio unit. You’ll also discover how  importing a file also imports a variety of drawing items such as layers and line

1. Begin the unit by drawing two rectangles, one 14′ wide by 24′ long, and the other 14′ wide by 4′ long. Metric users should make the rectangles 426cm wide by 731cm long and 427cm wide by 122cm long. Place them as shown in Figure 5.8. The large rectangle represents the interior of the apartment unit, and the small rectangle represents the balcony. The size and location of the rectangles are indicated in the figure
2. Click the Insert Block tool on the Draw- toolba.
3. In the Insert. box, click the BrO\\’Sl’ button and locate <1)1d select the bathroom drawinj; using the Select Drawing hie dialog box. Then click Open.

4, Click OK in the Insert dialog box, and then click the upper-left comer of the unit’s interior as the insertion point (see Figure 5.9). You can use the Endpoint Osnap to accurately place the bathroom. Use a scale factor of 1.0 and a rotation angle 0

5. Change the two rectangles that you drew earlier to the Wall layer. To do this, select the tw r ctanglcs so they are highlighted, then open the Layer dropdown list in the Properties toolbar and select Wall. Press the Ese key twice to clear the sclecuon

By inserting the bathroom, you imported the layer= and blocks contained in the Bath file. You were then able to move previously drawn objects to the imported layers. If you arein a hurry, this can be a quick way to duplicate layers that you know exist in another drawing. This method is similar to using an existing drawing as a template, but it allows you to start work on a drawing before deciding which template to use.
