Quicker Start Guide

Here is a quick procedure for using Blender in design work for Factor e Farm.

• Start by opening up 4 windows. First is the work window in Object Mode, in solid draw type: . The next 3 windows are in the x, y, z face views, with Object Mode, in wire frame draw type - so you can see how an object changes clearly along 3 axes.
• Mouse roller to zoom in and out
• Press mouse roller to move image
• Right click to select object
• Control-z to undo an action
• Pan with shift-middle mouse button

Blender Interface

Press middle mouse button to scroll menus/headers.

Navigating in 3D

Manipulating Objects

Selecting objects:

• Right click to select an object.

• You select multiple elements down an axis with control and left click to drag a lasso around the area to be selected.

To move an object:

• Left click or right click, move and release. This will start to move objects. Left click to finish moving.

• • Hold down control while moving to snap the object to the grid.
    • CAUTION: The object's center is snapped relative to it's position to the grid. To align the object to the grid use the 'Transform Window' with the N key.

To rotate an object:

• Press the R key. Hold control to snap to 5 degree movements. Left click to finish.

To scale an object:

• Press the S key. Hold control to snap to tenths of a percent. Left click to finish.

More operations, like select, duplicate:

Object Mode and Mesh Edit Mode

Object mode allows you to select and move objects, in any way desired. Mesh edit allows you to work on only the selected object.

• Control-Tab in edit mode allows you to select vertex, edge, or face.

Useful Hotkeys

Extrude: E

Merge vertexes: ALT-M

Detach part of mesh: P

W: "Specials" in mesh editing

ctrl=L: Select contiguous vertexes in mesh edit

Ctrl-J: join two objects

P: Detach parts in mesh edit mode

Inserting Objects

Left mouse gets the pointer to where new objects will be inserted.

Go to add menu, in upper left, add mesh - start with cube.

Transform Window

Press N. You can center an object to the grid by setting the position to a whole number.

Exam #1

• How do you select an object?
  • Right click
• How do you move an object?
  • Right or left click + drag + release
• Trick question: how do you insert an object?
  • Go to add menu, in upper left, add mesh - start with cube

Questions

Say you have parts on a screen. How do you align them?

Day 2

Add a camera. Turn on the lights. Render.

To delete objects, use function-delete

Integrated Set of Actions

Take a u-channel profile. Duplicate it (shift D), scale it (N), rotate it (R), and then align it in the appropriate window. Add a camera. Add lights. Blender.

Result:

Copy Objects - Duplicate

Shift-D

Split a Window

MMB on border, and select Split. Good tutorial:

Exercise

Split a Blender window into 4 windows. First is a 3D view window, and the next 3 windows are the 3 other planes: xy, yz, xz - to view the object from 3 different sides. Draw a cube. turn the cube into a 12x1 unit object (extended cube). Then draw a cubic lattice of 12 unit sides.

After all these steps are done, set up lighting and Render.
