Solution to Fig. 3.4 Outside Caliper

Here is the full solution to the Fig. 3.4 Outside Caliper taken from “The Tutorial Guide to AutoCAD 2011″ chapter 3 exercises. Here is the finished drawing: Fig. 3.4 Outside Caliper (AutoCAD 2007 Format).

The trick to this exercise is to draw what you know first, then fill in the more difficult details.

1. Draw a line from [2.5, 2.5] or any point on the screen with an endpoint @ 5.50 < 0°.

2. Now, draw a short line segment from the left endpoint of the previous line, make it about 0.5″ (i.e. @ 0.5 < 90°). This will serve as an offset marker to establish distances and the centers of our arcs/circles.

Solution to Fig. 8-100 Gasket

Here is the full solution to the Fig. 8-100, “Gasket”, taken from “Engineering Drawing and Design, 7th Ed.” chapter 8 exercises.  There seems to be a bit of “misinformation” on the dimensioning, however, with one slight adjustment you can construct this gasket dimensionally perfect.  You can follow the screenshots along as I go, or you can simply download the finished .dwg: Fig. 8-100 Gasket (AutoCAD 2007 Format).

Here goes, and BTW if you want to see any of the screenshots full-size simply click on the image…

1. Draw a line from [2.2, 2.3] (or any point on the screen for that matter) with the end point @ 1.8 < 60°.

2. Draw a line from the lower end point of the line just drawn, with its endpoint @ 2.20 < 0°.

3. From the end of the line just drawn, draw another line @ 0.70 < 90°. Then, from the right end of the line from step two, draw another line @ 0.52 < 0° and then @ 1.90 < 90°. Now going from the right endpoint of the horizontal line to the right most of the drawing, draw another line @ 0.40 < 0°. Now you have established the center of all the gasket holes you’ll need to draw.
