The 2′-6″ (762 mm) opening to the bathroom starts 30″ (762 mm) from the inside of the left exterior wall. You can’t simply offset the wall and trim the excess because the offset lines would not cross both the interior wall lines. Instead you will use the EXTEND command exactly …

Take another look at Figure 4.28, and notice that the opening on the right side of the cabin has one jamb set in 4′-6″ (1372 mm) from the outside corner. This opening is for the sliding glass door. You’ve done this procedure before, so here’s a quick summary of the …

This opening is on the back wall of the cabin and has one side set in 7′-10″ (2388 mm) from the outside corner: 1. Make sure I04-07-FinishInteriorWalls.dwg (M04-07- FinishInteriorWalls.dwg) is open. 2. Start the OFFSET command and then type 7’10↵ (2388↵) to set the distance to 7′-10″ (2388 mm). 3. …

Of the four doorway openings needed, two are on interior walls and two are on exterior walls (see Figure 4.28). Two of the openings are for swinging doors, one is for a sliding glass door, and one is for a set of bifold doors. You won’t be doing the hatchings and dimensions shown …

To do this trim efficiently, you need a closer view of the T-intersections. Use the ZOOM command to get a better look: 1. Make sure I04-05-WallCleanUp.dwg (M04-05-WallCleanUp.dwg) is open. 2. Type Z↵. Then move the crosshair cursor to a point slightly below and to the left of the upper T-intersection …

Earlier in the book, you used the FILLET command to clean up the corners of intersecting lines. You can use that command again to clean up some of the interior walls, but you’ll have to use the TRIM command to do the rest of them. You’ll see why as you …

Because the interior walls of your cabin are not load bearing, they can be a little thinner than the exterior walls. The standard thickness for your interior walls will be 4″ (100 mm). Using the strategy developed at the beginning of this chapter, you will create the cabin’s interior wall …

Next you will use the OFFSET command to create all the interior lines for the exterior walls at one time: 1. If I04-02-CreatePolylines.dwg (M04-02-CreatePolylines.dwg) is not already open, click the Open button on the Quick Access toolbar. 2. Start the OFFSET command by clicking the Offset button on the Modify …

Polylines are composed of segments, which may be straight or curved lines, and vertices that terminate the segments. Each segment must have a vertex at each end, but several segments can share a single vertex. The perimeter that you drew follows the major length and width dimensions of the cabin …

Exterior walls are slightly thicker than interior walls because they are sturdier, are load bearing, and have an additional layer or two of weather protection such as siding or stucco. Accounting for these properties, the standard thickness for your exterior walls will be 6″ (150 mm). Using the tools you’ve …
