A new episode of Blender and 3D printing - Precisions Modeling with Blender.

In this first part we will discuss the basic ways of working with the object's origin and the 3D cursor. In addition to the basic working methodology, I would like to highlight additional options for precision modeling with Blender. Working with the 3D cursor and the origin are the main tools for modelling that we need to know, to easily and fast create 3D models for 3D printing with Blender.

00:45 - What is the origin
01:36 - Global coordinates in transform section properties panel
02:15 - Change the origin using the 3D cursor
02:40 - Origin and active element, used for rotation
03:20 - Set the origin to various model parts
03:50 - Use the origin for translation
05:00 - Exact movement along an axis
06:00 - Exact movement and numeric input, use the shortcuts
06:40 - Use the grid for precise movement of modelparts
07:50 - Use measuring for precise modelling
09:50 - Use measuring for to st the correct angle
12:00 - Use 3D cursor to position vertices (also edges, faces)
13:00 - Origin and modifier, for example the mirror modifier
13:20 - Origin operations on multiple objects
14:00 - Rotate precisely and use pivot point settings
