AutoCAD Assignment 11: Basic Isometric Drawiug.

Before you begin: First, create a “AutoCAD_11” folder on your network space for this assignment. Save all of the following drawings into this folder.

The contents of this assignment: In this assignment, students will be learning how move their AutoCAD drawings into the Third Dimension, through the use of the Isometric Grid.

The Tutorials: Before beginning, review the following Tutorials:


  1. These videos were created by Mr. B. using the old AutoCAD 2002 version of the program. While some of the buttons and commands are slightly changed, the basics of ISOMETRIC drawing are the same, even easier in AutoCAD 2015. Do not let the older looking layout confuse you! Ask for help, if necessary.
  2. These videos explain how to INCREASE your CURSOR SIZE, helpful for Isometric Drawing. However, the process is different in AutoCAD 2015. With a canvas open, RIGHT-CLICK and select OPTIONS. Then click on the DISPLAY tab at the top of the dialogue box. Increase the CROSSHAIR SIZE to 40-50.
  3. There are two NECESSARY buttons that you will need to push in AutoCAD 2015 that will make your ISOMETRIC DRAWING much, much easier (See Drawing to the Right!) Make sure that they are visible in your bottom button row by clicking the 3 LINES button in the very lower right of your screen and making sure that ISOMETRIC DRAFTING and ORTHO MODE are both turned on. These commands are as follows:
    1. The ISOMETRIC DRAFTING button, new to us with AutoCAD 2016, which will automatically set up an isometric workspace for your drawing. This takes the place of the GRID SETUP that is explained in the video. Notice that the grid lines will now align with the plane that you are using, a very helpful addition.
    2. The ORTHAGONAL button (F8), which will restrict your drawing to the proper 30 degree angles, depending on which isoplane you are using at any time. If you ever need to draw a line OFF of the isometric angle grid, such as an irregularly shaped object, turn this feature OFF!)
  4. When creating an ISOCIRCLE, in AutoCAD 2015, you must click on the ELLIPSE>AXIS-END option, the select ISOCIRCLE (I) on the command line. You will be able to input RADIUS from this point!

The Problems:

DRAWING 1: Red Book, Page 515, Figure 35-12B: (Replicate this figure, estimate dimensions. If you haven't watched the ISOCIRCLE Tutorial, leave the circle for now, come back and draw it later.)

DRAWING 2: Replicate the figure below. You may draw the figure to any size that you wish.

Make sure that you have watched the ISOCIRCLE Tutorial before attempting the problems below!

DRAWING 3: Page 515, Figure 35-10: (Replicate this figure, estimate dimensions)

DRAWING 4: Page 513, Figure 35-8 (Replicate this figure, use all given dimensions for this drawing, estimate the size of the circles. SAVE THE 5.292 ANGLED LINE FOR LAST!) You DO NOT have to dimension this drawing [yet!])

DRAWING 5: Replicate the drawing below. Use the dimensions as given. You DO NOT have to dimension this problem!.

DRAWING 6: Replicate the drawing below. Use the dimensions as given. You DO NOT have to dimension this problem!

DRAWING 7: Challenge Problem #1: Replicate the sketch of an iPhone 4. Draw your figure to scale by researching the dimensions of the iPhone 4 on the Internet.

DRAWING 8: Challenge Problem #2:  (make sure you have watched the Advanced Isocircles Tutorial before you try this one!) Replicate one of the drawings below, make sure to select one that will be challenging for you! Estimate all dimensions.  You do not have to attempt the shading of the drawing.

DRAWING 9: Challenge Problem #3: Replicate the drawing below. Use the COPY command to create the inside “thickness” of the isocircles, as shown in the Advanced Isocircles tutorial. Use lots of TRIM.

DRAWING 10: CHALLENGE PROBLEM #4, Use the dimensions shown in the left side figure to create the isometric drawing on the right.
