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)
![Page 10: REU Modeling Course Day 1 - Iowa State University](https://reader031.vdocuments.net/reader031/viewer/2022012020/61688710d394e9041f70413a/html5/thumbnails/10.jpg)
๏ 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

๏ In the Perspective Viewport we can tumble/rotate around the scene by pressing alt/cmd + left mouse button.
๏ Alt + left mouse click = orbit around scene
๏ Alt + middle mouse button = pan/dolly scene
๏ Alt + right mouse click/ Alt + scroll wheel = camera truck: move away or towards
๏ Press F = frames selected object in scene
๏ Press A = frames all objects in scene

๏ 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
๏Check out Interactive Creation at the bottom of primitive creation
menu – step by step visual creation

๏ 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
Difference between NURBS & Polygons

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)

Resetting Transformation
๏ 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 done up until that point
๏ Reset transformations on the selected object back to zero (return to first or last “frozen” position).
๏ select object > Modify > Reset transformation
![Page 29: REU Modeling Course Day 1 - Iowa State University](https://reader031.vdocuments.net/reader031/viewer/2022012020/61688710d394e9041f70413a/html5/thumbnails/29.jpg)
CAD Programs Mini GoalMaya Interface Polygonal Models
Freezing Transformation
๏ Controls which types of transformations (translate, rotate,
scale or join orient) are frozen
๏ Re-defines origin to zero in the new
transformation. Freeze transforms
sets all values back to zero without
physically moving the object back to
origin.
๏ select object > Modify > Freeze transformation

views and press the spacebar again, it
will fullscreen that option.

Let’s get abstract!
๏ Mini Activity: 10 - 15 minutes
๏ Explore how tools affect vertices, faces & edges
๏ Start with 3 shapes and edit them until you can no longer recognize the original shape
๏ Turn into an abstract shape or a different object
๏ Test different scenarios
๏ What happens if a face is deleted?
๏ Can you add a face back in to complete the object?
๏ Showcase to everyone at the end of the activity

Today’s Mini Goal
Good: Create 3 objects: a small house, tool shed, or barn house with a
landscape or “floor” to rest on + a fence + a single object that could move
(ex: animal, tumble weed, wagon)
Use most of the tools you learned in class today.
Better: Add 4 or 5 more smaller elements = rocks, bench, bush, picnic table,
bench, chairs, table, chimney, stepping stones, etc.
Even Better: have 6 or more different elements in your scene that complement
each other in the scene (example: tool shed, stepping stones, toolbox, garden box,
fountain, etc).
