1 REU Modeling Course Day 1 AutoDesk Maya - Program Introduction + Getting Started

2 Workshop Workflow Compare/introduce CAD programs and purposes review Creating/Experimenting with Today s mini goal

3 CAD Programs Today s Inspiration

4 VRAC Computer Aided Design (CAD) Flavors Digital Product Design (DPD) Concept Design Marketing Engineering Manufacturing VRAC Other Visualization Format Free-Form Modeling Design and Modeling Rendering and Animation Exchange/Conversion Post Processing CAD Programs

5 Free-form Design & Modeling CAD Free-Form Modeling CAD DPD Free- Form - Design and Modeling (only) Other - Scene Rendering and Animation - Examples: - Cinema 4D - 3DS Max - Blender - Rhinoceros 3D CAD Programs

6 Other Free-form modeling Conceptual Design: ASDS, SpaceClaim, Fusion 360 Visualization: OpenSceneGraph, Unity DPD Free- Form Sculpting: MudBox, zbrush, Form Z Other Mesh Edit/Repair: Materialise Magics, Rhino 3D Data Translation: SAP Visual Enterprise CAD Programs

7 CAD Programs Let s Jump in to Maya

8 Autodesk : Component Map A B Today s Interface C components focus: A. Menu Bar E D B. Status Line C. Shelf D. Channel Box E. Toolbox F F. Workspace CAD Programs

9 Project File / Menu Bar Saving projects: Make sure to create an empty folder to save your stuff in your desktop (we want to make sure to keep everything from that project together) On the top: The items such as: File, edit, create, select, modify, display, window. NEVER CHANGE. Everything else in that line will change according to the menu set (under file/edit, dropdown box) CAD Programs

10 CAD Programs Menu Sets Menu sets include: Modeling, rigging, animation, FX, rendering, customize Use MODELING menu set for all of today s workshop. Next to it we also have icons that allow us to: create new scene, undo, redo, file, save

11 Moving around in Maya In the Perspective Viewport we can tumble/rotate around the scene by pressing alt/cmd + left mouse button. Alt + middle mouse button = pan/dolly scene Alt + right mouse click = zoom in/out OR use scroll wheel Press F = frames selected object in scene Press A = frames all objects in scene CAD Programs

12 CAD Programs Difference between NURBS & Polygons NURBS (Non-Uniform Rational B-Spline Surface) Has a lot less details for the same amount of curvature due to it s patch-based modeling system It s Composed of curves rather than straight lines Less flexible when it comes to modeling POLYGONS Can create objects much quicker and easier Larger tool availability in Maya Used more frequent than NURBS

13 Polygon Models: Primitive Types Polygon Primitives include: Sphere, cube, cylinder, cone, plane, torus(donut), prism, pyramid, pipe, helix, soccer ball, platonic solids. To create primitives go to Create > select desired primitive. Automatically dropped in the origin (X = 0, Y = 0, Z= 0) Can be also dragged and created CAD Programs

14 Polygon Models: Channel Box Editor To the right of the screen: The Channel Box/Layer Editor will appear Let s you know you have created a primitive (ex: pcube1) Provides all of the properties for that object Can change the object s subdivision, radius, etc. CAD Programs

15 CAD Programs Polygon Primitives: Progress

16 CAD Programs Working with the Outliner Provides one entry for every object in the scene (objects, cameras,lights,etc.) Found in: Windows > Outliner or Panels > Outliner or on the side panel Allows you to select and arrange objects around. Shift click for all and in-between Control click for single-multiple objects

17 CAD Programs The Toolbar & Functions Select (Q) Move (W) Rotate (E) Scale (R)

18 Selecting Objects Select = Hotkey Q Left click outside the object to de-select Select multiple by left click + shift OR left click and drag (marquee box) Click spacebar to select various Polygonal components (vertices, faces, edges) CAD Programs

19 Maya Viewports Viewport can be changed by hitting the spacebar. The views are orthographic (display scene elements without perspective) Top, Right Side, Front, If we put the mouse over one of the views and press the spacebar again, it will fullscreen that option. CAD Programs

20 CAD Programs

21 Moving Objects Move = Hotkey W Manipulator/Handles will appear, these let you translate on a single axis (X,Y,Z) The different boxes will move 2 axis it is standing between. We can move various objects at the same time CAD Programs

22 Duplicating Objects Not a tool, but a handy function. Duplicate = ctrl + D OR Edit > Duplicate Manipulator/Handles will appear, these let you translate on a single axis (X,Y,Z) New duplicate is its own object (rename it) We can duplicate various objects at the same time Can also do the traditional right click + copy/cut and paste method, but duplicating is quicker. CAD Programs

23 CAD Programs Duplicating Objects: Progress

24 Scaling Objects Scale = Hotkey R Only works around the object s pivot point Manipulator/Handles will appear, these let you translate on a single axis (X,Y,Z) The different boxes will scale 2 axis it is standing between. We can scale various objects at the same time Specific proportions can be specified in the channel box, where the object s properties are CAD Programs

25 CAD Programs Scaling Objects

26 Rotating Objects Rotate = Hotkey E Only works around the object s pivot point Manipulator/Handles will appear, these let you translate/scale on a single axis (X,Y,Z) The different boxes will scale 2 axis it is standing between. We can scale various objects at the same time CAD Programs

27 CAD Programs Rotating Objects

28 CAD Programs all of these tools can be used on: points(vertices), faces, & edges

29 Resetting Transformations Resets or brings back an object to its original position without affecting other objects Neutral state = (x = 0, y = 0, z = 0) It will NOT undo what you have don up until that point Reset transformations on the selected object back to zero (return to first or last frozen position). CAD Programs

30 Freezing Transformations Controls which types of transformations (translate, rotate, scale or join orient) are frozen Freeze transforms sets all values back to zero without actually moving the object back to origin. It basically sets (resets the origin point of an object, yet it can still be transformed) select object > Modify > Freeze transformation CAD Programs

31 Snapping Objects Positions objects precisely in relation to other objects/options Selected objects will: Snap to grid Snap to curves (NURBS function) Snap to points (vertices or points in another object) Snap to projected center Snap to view planes (will need to create arbitrary planes) CAD Programs

32 CAD Programs Snapping Objects

33 CAD Programs Today s Good: Create 2 objects: a small house, tool shed, or barn house with a landscape or floor to rest on + a fence (can surround a small area or the whole plane) Use most of the tools you learned in class today. Better: Add 3 or 4 more smaller elements = rocks, bench, bush, picnic table, bench, chairs, table, chimney, stepping stones, etc. Even Better: have 5 or more different elements in your scene that complement each other in the scene (example: tool shed, stepping stones, toolbox, garden box, fountain, etc).
