All of a scene is constructed from one or more Objects. For example Lamps, Curves, Surfaces, Cameras, Meshes, Armatures… Each object can be moved, rotated and scaled in Object mode (). For performing more detailed changes to the geometry, you will have to edit its ObData, using Edit mode.
Objects are typed: a Mesh object is not the same thing as a Curve or Camera object! An object of a given type might switch its “internal data” (e.g. use another mesh), but once created, an object cannot change its type (a mesh cannot become curve), unless it is converted. Here are the available types of objects:
- mesh (code:
- curves, surfaces, and texts (these are different kind of objects, but they seem to use the same object type… code:
- metas (code:
- empty (no data code, as it contains nothing!).
- group (no data code, as it is a “proxy” of real objects!).
- camera (code:
- lamp (code:
- armature (code:
- lattice (code:
Once you’ve added a basic object (Add » Mesh/Curve/Meta/…), you may be automatically switched into Edit mode (if the object is a Mesh, a Curve or a Surface). Note that this depends whether Switch to Edit Mode is activated or not, in the Edit Methods “tab” of the User Preferences window. You can switch back to Object mode by pressing ⇆ Tab. The object’s wireframe, if any, and its center point, should now appear pink, meaning that the object is now selected and active, see (Selected object).
In this part, we will see:
- How to select objects.
- How to edit objects.
- How to group and parent objects.
- How to track objects.
- And the various types of object duplications.
But let’s talk first about some miscellaneous important things.
You have several options about objects visualization, located in the Draw panel of the Object context and sub-context (F7).
- In its top part, this panel allows you to control the layers on which the active object exists, as well as its object color and alpha (a face shading/texturing feature).
- This buttons group allows you to restrain the drawing type of the active object. For example, if you set it to Wire, it will remains in wireframe, even if the view draw mode is set to Solid, Shaded or Texture. However, if the view draw mode is set to Bounding Box, this object will also be drawn as its bounding box… Note that there is no Textured option here – Shaded also means “textured”…
- Draw Extra
- This buttons group regroups some extra drawing features:
- Bounds – This will display the bounds of the active object. Note that it might be the “bounding box”, or a more complex one, depending on the setting of drop-down Boundary Display menu, just below (other options are Sphere, Cylinder, Cone, and Polyheder, the “tightest” option…).
- TexSpace – Displays, materializes the active object’s texture space.
- Transp – Uses the transparency of the active object’material in 3D views (only in Solid draw mode, for meshes).
- Name – Prints the name of the object, next to its center.
- Axis – Draws the local axis of the object.
- Wire – Always draws the wireframe of the object, whatever being the draw mode…
- X-ray – Always draws the object on top of the others (note that when several objects have this option set, the closer ones occlude the more away).
