AutoDesk offers all of their software to students for free, you just need to verify your eligibility with a .edu account. You can get started right [here].

AutoCAD is the standard tool that’s been around for decades. It’s also AutoDesk’s only tool that’s available for both Windows and Mac. If anyone has a Windows machine, you might want to check out AutoDesk’s Inventor. AutoCAD was designed for 2D elevations first, 3D models second, whereas Inventor was created with a focus on 3D drawing. Supposed to be comparatively easy.

James also mentioned [Blender] last weekend. Free, open-source, Windows & Mac. People say the interface is a little difficult to deal with.

Blender: Using Shrinkwrap Modifier to Create a Shell

You can use the shrinkwrap modifier  to create a shell of an object in blender.

Object Mode

1. After successfully shrinkwrapping an object, you will need to select the plans that were used to shrinkwrap the target object. On the right hand tool panel you will see a list of your objects. Hold shift and select the plans that are shrinkwrapping the object.

2. On the left hand tool panel, select “Join” to connect the plans as one unit. The plans should be renamed. For example, if you joined Plan-1 through Plan-5, the plans will appear under one title (Plan-1).

3. With the shrinkwrap mesh selected, press G + move the mesh away from the target object.

4. You should now have a mesh shell.

Bender: How to Shrinkwrap

Shrinkwrap Modifier: This modifier allows an object to shrink to the surface another object. Like shrinkwrap, the modifier can be used to seal an object.

How to use Shrinkwrap: 

1. Add a mesh (ex. cube, sphere, etc.). I will refer to this mesh as Object-1.
2. Scale down Object-1 so that it is reasonably small. (Scale: select object, move mouse away from object,  press S + right click, adjust size, left click)

3. Add a mesh plan. I will refer to this mesh as Plan-1.

4. Scale Plan-1 so that it is larger than Object-1.

5. Orient Plan-1 so that it relates to a surface on Object-1. For example, if Object-1 is a cube, then Plan-1 could be placed parallel to on of the sides. The cube icon on the right hand tool bar provides and easy way to rotate or move Plan-1 precisely.

6. Select Plan-1. On the right hand tool panel, click on the wrench icon. This icon allows you to add modifiers. Click  “Add Modifier” and under deform, choose shrinkwrap.

7. Make sure you are in object mode.

8. You will need to select your target object. Click on the target selection space, and choose Object-1.

9. Select Apply.

10. Repeat steps 3-9 until the surface of Object-1 is completely covered.

BLENDER BASICS

Hello all-So Blender is a platform we will be starting on in class.

We’ll go over this, but here are all the references we’ll use in class:

Blender Basics

1)      Orientation:

-To rotate view without using the mouse:  use keyboard number-pad

-To Translate/Rotate/Scale using the mouse on a specific access: g/r/s+x/y/z+degree

-To lock Translate function on an axis: g + x/y/z

 

2) Object/Edit Mode (Tabbing):

-Hotkey to switch Object/Edit mode:  Tab

 

3) In Edit Mode:

-Select Vertices, Edges or Faces using the icons.

-To extrude on any Edge or Face: Select face + E

 

4) Parents and Groups:

An object can only have one parent. You can use this to set up a hierarchy.  Objects can belong to multiple groups.

NOTE: Objects made in the Edit mode of another object become grouped with the first object in the Edit Layer.

Parents:

-To set up a Parental relationship between objects:

Select all objects and leave the last one as your parent object.  Then:

CTRL +P: Object: Parent

-To clear a Parental relationship:

Select Child object: Alt+P: clear

 

Groups:

To make a new group-> Select objects>(CTRL+G)

To remove from Group: Select objects>(CTRL+ALT+G)

 

Active Groups:

To add other objects to all other groups associated with the highlighted object-

Add Selected object to Active Group:

Add Select object belonging to other groups->shift+ctrl+G)

Remove Select object belonging to pother groups->shift+alt+G)

 

5) Using Meshed Solids to make forms

Add>MESH> UV Sphere

To modify Edge rings and Vertices open in Edit mode.

VERTICES: Select Vertices-> Move

EDGE RINGS: ALT+select edge ring-> move
