Basic Building in
Where to get Blender Go to www.blender.org Download the latest version Heads up! If using Linux the Software Center's safe version is out of date and doesn't do all that the new one does, why Blender.org is the best place for a download.
What is Blender Blender is a 3D building program that does all kinds of things! You can make low poly models for games You can build a game in it's game engine using Python programming You can build high poly models for art with its own Cycles rendering system You can do animations with it for games or CGI moves. You can do ridged body simulations with it... It does all kinds of tricky cool stuff...
In this presentation ill show you Basic moment Basic simple modeling Modify them Go over some modifiers And get you started so you can use Blender for what ever modeling you might need ' )
This is the Splash Screen
Splash Screen The splash screen can take you to any projects you have been working on and a bunch of helpful sites Click anywhere outside the Splash Screen to just start working on an empty project.
Your basic empty project or scene
What the mouse?! The controls are a little hard to get used to so hear is the simple skinny run down Right click selects objects, you can switch this in preferences if you like ' ) Middle mouse wheel click rotates freely in the environment around selected object Shift + middle mouse click strafes your view with out rotation Mouse wheel zooms in and out on object Ctrl + mouse wheel click = a better zoom
Hot Keys T = Tool bar N = 2nd Properties window G = Grab R = Rotate on current view RR = free Rotate S = Scale G, R, or S + X,Y,Z moves one one axis only A = select everything E = Extrude
More Hot Keys Shift+A = Add Object selection screen Ctrl+A = Location Rotation Scale reset menu F = Fill (fills any 2 selected non terminating spaces on an object) Shift+D = Duplicate C = marque tool (a selection tool) Tab = Edit Mode H = Hide object (Alt+H un-hide) B = Box selection tool
And yet more Hot Keys Ctrl+B = separates a seem on your object mesh and adds a new face. M+(number) = move to layer Alt+M = Merge when selected vertices's U = UV unwrap menu Ctrl+P = Parent menu ~ = shows all objects on all layers Ctrl+R = add Edge loop And there are a bunch more but those will get you started.
Preferences A few things that may get you going faster Doesn't work LOL Turn on continues Grab If no 10 Key hit turn this on
And one important little helper Add-ons Type image Add this. It makes it really easy to scale objects to blueprints.
Simple building Find a simple blueprint like a car, plane etc that has front and side orthographic views Under file import as plane your blueprint. The plane is mostly to tell the correct scale as you build. Press 5 which sets the view in orthographic
Simple Building Blender gets disorienting so I often add a plane with my blueprint for scale and center it how I like
Move the cube with G Scale the plane with S Press N for 2nd preferences menu then click Texture Solid to see the image
R Z -90 Rotates our plane in to place Or you can use this but using Commands makes it way More accurate
brings Pressing 5 view on ic h p a r g o orth above s u s g in r b And 7 our plane Select the cube And zero out its location Use G on the plane to aline it on the Y
Tab in to edit mode Add a loop to the cube mesh With Ctrl R Then delete the remaining faces on the positive or negative side of the Y axis The wrench is the modifier menu
HARD PART IS OVER!!! Ctrl R will add loops then selecting the faces you can edit the mesh match our blueprint These controls select faces, edges or single vertices's You'll want to turn Clipping on Trust me!
To see through your image select Wire Under object display ow n d a oks b ' ) o l t i ry if ool soon r o w t Don' will look c It
Shift D will duplicate our image then rotate it in place Do this for a all views of your object Then start shaping the faces to match
You can change the color of the Wire Frame to make it easier to see in preferences under Thames. You can actually change almost anything for that matter. Click the Wrench for modifie And add multiresolution You'll like this one ' )

Setting it to 2 us normally enough. You can set more later. Multiresolution takes vertices's from 3 points and then mathematically adds more loops to the mesh. It lets you build smooth shapes however you will need to add more loops to make the shape match. Note: if you Tab between edit and object mode you can see the see your object mesh with mutiresolutin off
Score as many visual references as you can. If in color like this one they work nice for game models. Problem spots like this are easy to clean up once you get the major parts down. The harder part is learning good topography. Edit mode on multi res it will look boxy Object mode you can see how it will look once you add apply the modifier
Making good topography can be a nightmare at first and its more an art. You can use the smooth tool bar, or collapse edges or make a remesh the skin In this case I am just deserving edges while only saving the ones I need. ey Hot K e model icolat o t \ Use
Sometimes No matter how you try you just can't get vertices's where you want them. So we need a little help! Thankfully there if you press T for tool bar There is this subdivide button witch evenly divides the edge
Once you have added vertices's you can merge new edges together with Alt M Trust me Ctrl M And Ctrl B will save cost on headache meds ' )
Trouble shoot! Whisk Tango Foxtrot!! Some times you come across this. It happens when you Extrude twice and don't notice. To fix simply hit Z go in to Wire mode and press C to select the vertices's that you just extruded and use Ctrl M to merge them together Trust Heada me on this! che S aver ' )
For the engines because they are hard to see I'm going to add a new cylinder then combine it to the first mesh. However a normal cylinder has way more vertices's than what we need. Press F6 just after adding the Cylinder for a sub menu to edit the number of vertices's
Simple Rules of Topography Before adding new things to the original mesh plan ahead and clean up the topography When working with multi-res modifiers if you don't need vertices's to help the shape of the mesh, dissolve them pressing X and its sub menu If you have terminating loops in the mesh try and tuck them away with Alt+M in a flow for better for better printing and smoother flow
To join objects, first select both. Next we place the cylinder on the -Y side and hit the Join button in he tool box. Or you can simply use the hot key Ctrl J. Because of mirror and multi-res modifiers we will get a second smooth cylinder.
Sometimes areas are hard to see. You may have to hit 5 to go in to perspective view then take the camera inside the mesh. This can get vary disorienting so press N for the 2nd properties menu, then under shading check Backface Culling. This lets you see what walls are inside or outside. This can be vary important when making models for 3D printing.
F op en Some times you will have to close gaps. For this just select the edges and hit F! And presto its Fing closed ' ) space s!!
For open areas like the air inlet's and tail cones getting them to look right can be hard. For these hold Alt+Shift to select a whole loop then press E and then S. You will scale all walls extruded at the same time.
Almost Done Now I'm going to show you a little cheat to make the vertical stabilizers. Hit space bar and type add plane Rotate it 90 degrees on the Y axis Type R Y 90 Next give it its basic shape.
Add intersecting lines on the edges anticipating the mulit-res modifier it will soon be connected to. Note: to make it easier In properties under display you can check X ray to see the object in front of anything
When creating really simple things like fins, wings, building floors, geometry, blades, etc just add a Solidify modifier to a plane
Apply the solidify modifier Then join the tail to the aircraft Be sure to hold shift and click the tail then the aircraft before joining
Finally for this tutorial we are going to finish the cockpit. Click on this icon and select Individual Origins. This way when you extrude, it will be even on in all directions of any faces selected
