## INTRODUCTION TO MODELING IN AUTOCAD -- BASIC CONSTRUCTION, EDITING, AND VISUAL MANIPULATION.

• The file naming convention for all of our ACAD files will be yourinitials3Dnumber of drawing. For example my first file will be named JMK3D1
• Templates – choose the 3D template to begin
• Reacquaint yourself with AUTOCAD by completing a 2 dimensional CADD assignment. The instructorwill assign one or two drawings.

LAYERS - Creating layers for each part in a 3-D object ---- Use different layers for the different features.
Workspaces – set the workspace to 3D
VPORTS- splitting the screen into various view configurations
BOX – drag curser in the 3 axes consecutively to create solid rectangular shapes
CYLINDER - to create solid cylinders
CONE – to create solid cones
SPHERE – to create solid spheres
MOVE and COPY– to move or copy objects
SUBTRACT - to remove pieces or geometric shapes from solids
UNION - to join solids together permanently
Z—E     zoom extents
Z—1    zoom to a scale of 1
VIEWCUBE– to view images dynamically from various perspectives and as they are shaded. Know shading modes –gourad and hidden

BASIC SHAPES AND WORKING WITH TILES
Use the commands above to create a simple image of a character head that may be used in a future animation. This exercise will help you learn how to navigate using 3-D orbit and move and copy items in various tiles.

PRECISION MODELING
Lesson: Use Guide Block on page 162 (Basic Technical Drawing) to introduce precision modeling techniques ---- Remember to use the 3D template for printing purposes

BOX – explain other options of the box command (length option and direct click method

Applying Autocad 2000 Book  Pg. 1011, 1012, 1013 Fig. AV8-1
Draw as 3-D image using the text and figures shown over the 3 pages.  Read the pages for important information as to construction procedures and sizing of parts. Ignore the bulleted items on page 1011.  You should not simply look at the pictures.

Optional : See me for a hitch pin example when you have completed the 7 main pieces. Draw the hitch pin as if it were in place on the clevis pin. (in an opened position)

Place all parts together in an assembly to be printed as described below:
Print 2 pages and staple together:
Page 1--one single southeast isometric view of the whole assembly together! Not to scale.
Page 2—2 tiles beside one another--a properly scaled front and right side view of the whole assembly together.

3-D Studio Topics

Harnessing 3-D studio Max 8, Aaron Ross and Michele Bousquet
Peruse chapter 1
Read pages 24 to 51 lightly to get an understanding of the workings of the program.
We will begin working and Saving exercises in various chapters. Saved files begin in chapter 2.
Use the following convention for saving work:

All exercises will be saved beginning with your initials, then followed by a hyphen, then the chapter number – exercise number. For example, my first exercise would be named JMK-2-1. Do not use a period between the chapter number and the exercise number. This will foul up the extension of the file and make it useless.

I will give you a list of exercises for which you will be responsible. All of your exercises will be graded. Save then in their finished form and in any significant steps that would demonstrate completion and mastery. Prior to each tutorial is resource information explaining the concepts used in the upcoming tutorial. I would strongly encourage you to fully read the reference text for the first few exercises to get the big picture—then begin skimming the reference text for later exercises after you are comfortable. Never completely skip the text prior to the exercise. It will give you an understanding of what you will do and why.

Here is the list of exercises to be saved individually:

Studio Animation Technique (Independent work)
Save this as _ _ _ (name this the type of technique you chose)
From either of the 3-D Studio books found on your desk, choose an animation, lighting, or materials concept that was not covered in early chapters of the Bousquet book.

DO the tutorial from the book to demonstrate the use of that concept. Prior to choosing your technique, please read the ANIMATION Project (Final Project) below to determine if you would like to incorporate your concept into this final Project.
Sample topics include, but are not limited to:
· Explosions/Particles
· Camera blur or other camera effects
· Lighting/Lens effects
· Dummy objects
· Advanced materials
· Warps and Morphing
· Nurbs
· Etc., Etc., Etc.

ANIMATION Project (Final Project)(remaining time)
Save this as _ _ _ (put some descriptive name in here)
Demonstrate the use of the tutorials you completed in chapters 2,3,5 and 6 as well as any other concepts you’ve learned.

I will need everyone to give me a storyboard freehand sketch prior to beginning this project. The sketches do not need to be involved, but need to be descriptive enough to demonstrate what is going to happen. IE. You can use stick figures if you absolutely need to do so.

The animation should include the following:
1 or more objects created in 3-D Studio
1 or more objects created in AUTOCAD and imported into 3-D Studio. Make this(these) somewhat involved.
Apply materials, textures, and/or maps to objects
Animate 1 or more parts or create animation through camera movement, etc.
Develop this project to the level of your ability—do not make it too simple or too difficult

Present your animation (approximately 5 minutes) during the last 3 days of class and explain the concepts behind your work.

Potential Extra Work

2 minute presentation on machine model
General format of Machine Model presentation:
· 2 minutes
· Show a print of the finished product or show it on the computer
· Explain how you simplified the model of your assigned machine to fit the allotted timeframe. Also discuss any special commands you used to accomplish the construction of your model. Explain the most difficult situations that you encountered and how you handled them.
Machine Animation (2-3 days)
Save this as _ _ _ (name this the type of machine)
Import the machine that you created in AUTOCAD into 3-D STUDIO MAX, apply materials to make it look realistic, then animate the moving parts. If there are few moving parts, you could animate the wood or other piece of material that the machine is meant to process. You could also create animation by moving the camera.
