When I was studying at Atlantic, I used to take notes of how to do stuff on the program used so I won't forget. Here it is some of those useful Notes, some of them are unfinished and some of them are written in spanish for obvious reasons. Either way I hope they help you out the same way they still help me!

I'm still going to edit this simple document the more I learn  [if I do so]!

Two edits:
Edit 1: is at the side of "Draw"
Edit 2: small windows between
          Draw and File windows

To move object: ALT
Quicksave shortcut: 9
• Zoom In and Zoom Out: + & -
To drag object: Hold Alt and move
Geometry -> Dynamesh -> clickable Dynamesh

To save project [IMPORTANT]:
Right side of the screen "Tools"
-> Save As

To expand Viewport:
Document -> Click "New Document" [Make sure the WSide is activated]

Once the basic figure is chosen click at Edit 1.

Create a mask:
Hold CTRL and "draw"

To erase mask:

To make the geometry transparent:
Go to Transform -> click on "TRANSP"

To do an Ear:
Create a mask -> Go to Subtools --> go down to Extract ---> Thickness set to 0.07 ----> click Extract -----> ACCEPT to avoid it disappear
Click MOVE -> unlock the lock -->  move it to the ear at the side ---> Lock it ----> Rotate outside

To do an Eye:
Expand the brush wide enough without going out from the object -> Hold ALT and circle movement --> go to brushes and select 14 IMM Primitives ---> Select Insert Sphere ----> hold SHIFT  and drag to place it right -----> Go to Subtools, Click Split ------> Click Unmasked Points

Make sure Extract is at Thickness 0.07

Note: Everytime you use Extract, click on the 2nd Extract that appears and click ACCEPT

(Not full detailed instructions, INCOMPLETE)

For the Pivot:
Click on the Move at the right side of Draw
Divide: es para detallar(aumento de pixeles) [preferiblemente utilizarlo cuando la pieza está completa] 

Dynamesh: es para esculpir. Aumento de geometría o disminución (preferiblemente usarlo mientras se esculpe)

To create pores:
Go to the Alpha Settings and click on Alpha07

Material: SkinShade4
Turn on: Mrgb
Then go to Color and select FillObject
Turn off: Zadd and Zsub

Rendering the sculpture:
Turn off Dynamesh -> go to the Alpha Brushes and select the Alpha07 to do the pores --> Hold ALT to make the pores while 'brushing' and press SHIFT occasionally to soften it ---> go to the Color file and click on FillObject ----> Material must be changed to SkinShade4

How to put a texture:
Go to Texture -> Import and open --> click on the picture in Textures ---> Click on Add to Spotlight (scale is to zoom in or zoom out) ----> scale it, edit it to be closer(similar) to the sculpt -----> Alpha must be turned off---> Second brush in "Free Hand" --> Standard brush set to Paint -----> Press Z -> set Spotlight and edit the Picture ---> scale a little the Spotlight radius ----> paint the object

Photoshop edit for Brushes:
Click on "Create a New Fill" [●]-> Add Black and White --> Add a new layer ---> Select Multiply ----> Select the "Paint Bucket tool" and click it on the image, be sure to be in black -----> Click on the Brush Tool ------> Make sure the Brush stroke is in "Soft Round" -------> Make sure the colors are inverted (White not Black) and size up the Brush --------> click on the image NOTE: Save as JPEG

Sculpting Brushes:
Take a Plane3D -> Click on Make Polymesh 3D --> Go to Divide on Geometry session ---> click on it until poly count reaches 1million

When copy the same body in another subtool and desire to leave the hands alone(Dynamesh fix):
Go to Modify Topology -> Click on Delete Hidden [Del Hidden] -->
Go to Dynamesh ---> Set Resolution to 242 ----> Click on Dynamesh

To isolate a piece:
Control (Mac iOS <COMAND>) + SHIFT -> Drag  around the piece desired to isolate

To Isolate a piece(Return):
Hold Control(Mac iOS <COMAND>) + SHIFT -> click outside

To Hollow out a piece in the sculpture:
Mask the area wished to hollow out -> go to Subtools --> Split Unmasked Point ---> Erase the Split (Delete) ----> Select sculpt----> Select brush Curve Bridge -----> Drag the area until the "masked part" and click shift (do it in front and back [Masks])

• Si el trabajo que se realiza no sale en los dos lados aun usando la simetría continua hasta que llegues al resultado deseado luego se va a Geometry -> Modify Topology --> Mirror And Weld

• Si el Mirror and Weld no funciona tendrías que ir al menú de Deformation y le presionaba Mirror para invertirlo, luego  utilizas el Mirror And Weld

Instant design:
Make a design using mask -> Hold Control + Alt and click out (mask will get darker) --> Hold Control only to invert mask ---> Double the size of the brush ----> Pass it in the "Unmasked" area -----> Control and drag outside

If Symetry it isn't working properly:
Go to Modify Topology -> Mirror And Weld

To put background images:
Activate the Floor -> Go to Draw --> Front Back ---> Map 1 ----> Upload picture

If cannot insert a new geometry:
You might have clicked Divided -> go to Del Lower

To duplicate a geometry:

How to create brushes manually (without pictures):
Go to where the geometric figures are -> Choose PM3D-Plane3D --> click on "Make PolyMesh 3D" ---> Go to Geometry and deactivate the option Subdivide Smooth Modifier[SMT] ----> Click Divide until the PolyCount  reaches 1million -----> Create the design for the brush (NOTE: It CANNOT touch any borders) ------> Once done, Go to brushes -------> Click on "Create MultiAlpha Brush" --------> Try it out, play with Intensity(Z Intensity) and Focal Shift  ----------> When done testing, Go to brushes again  ----------> Click on "Save As" -----------> Assign a name to the brush made

NOTE: The brushes does not save in the program automatically but outside of it

To use customized Brushes

Click where the brushes are -> go down --> Click on Load Brush ---> Select desired customized brush ----> Done

NOTE: You have to repeat these steps every time You use a customized brush

If for some reason you had done a "screenshot" (nothing seems to be working and it's overlapping everything else):

How to make a bridge in 2 seconds:
Go to move-> Click on the gear --> click on Bend Arc option ---> curve moving the center green arrow ----> adjust at likings -----> click accept to make it permanent and done

• Keep practicing, do tutorials to help and understanding the program and how to work
