By default, the view-ports Camera view in Blender displays the view from the camera that is set as the scene’s Active Camera.
If you split the view and in the new view select a different camera and set it as the Active Camera, the view in other view-ports set to camera view will update to display the new Active camera.
In short, by default, it seems you can’t assign different camera views to different view-ports..
But you can…
You just have to unlock the wanted view-port from the scene’s Active Camera by de-activating this button:
When the Use the scene’s Active Camera and layers in this view button is de-activated, your allowed to set an Active Camera for the specific view-port without changing the scene’s Active Camera setting, therefore not affecting other view-ports displaying the camera view.
Use the Select Pattern tool to select multiple objects with name similarities.
In the 3D View in Object mode choose Select > Select Pattern…
In the Select Pattern dialog, type a part of a name with an Asterisk to define wild cards.
For example *car* will select all objects who’s names contain the string ‘car’,
And car* will select all objects who’s names begin with the string ‘car’.
The Set Origin Tool let’s you set the origin (pivot) for one or multiple objects.
Typical usage would be to place the 3D Cursor at the wanted location and choose Origin To 3D Cursor.
Another handy usage is after “breaking” a model into separate meshes, like separating the letters of a title for animation, selecting all the letters and choosing Origin to Geometry to set all the letters origins to their centers.
In large scenes, selecting objects becomes slow.
There’s a frustrating lag and the software hangs between the time you Right-Click an object in the view-port, and the time it gets selected.
* especially if there are a lot of mesh surfaces behind it in the view-line of the mouse cursor.
The Systems settings shown below can dramatically improve this.
* You need a GLSL capable video card.
When appending items from a different blend file,
Check the Fake User option to automatically set a Fake User to the items.
This means that appended items that are not used within the file will not be deleted when closing it.
It’s useful for times when you append a whole library of materials or other assets into a file, so that you don’t have to make use off all of them before saving and closing, and they will still be available in the file the next time you load it.
In other words, you wont need to append the assets again the next time if you didn’t make use of them..
To create and edit measurement Rulers & Protractors:
In the Tool Shelf > Grease Pencil,
Press Ruler/Protractor to activate Ruler/Protractor mode.
LMB Click & Drag the 3D Viewport to create a measuring Ruler.
* Hold Ctrl while creating the Ruler to snap its start and end points to 3D elements.
* If a one or more measuring Rulers already exist, Ctrl must be held anyway to create a new Ruler.
LMB Click & Drag along an existing Ruler line to turn it into a Protractor for angle measurement.
* Hold Ctrl while creating the Protractor to snap its apex to 3D elements.
LMB Click & Drag a point in an existing Ruler or Protractor to change its location.
LMB Click an existing Ruler or Protractor and Press Delete to delete it.
When finished creating measurement Rulers & Protractors, Press Enter to save them for later use of the Ruler/Protractor mode,
Or Press Escape to discard them (without discarding Rulers / Protractors that were previously saved).
To Delete all Ruler / Protractor data:
In the Properties Panel > Grease Pencil Layers,
Delete the RulerData3D Layer.
