What does it mean to lock a transformation to two axes?
Plane locking locks the transformation to two axes (or forbids transformations along one axis), thus creating a plane in which the element can be moved or scaled freely. Plane locking only affects translation and scaling.
How to lock translation to the z axis?
For example, if the current transform orientation is set to Normal , pressing G to start translation, followed by Z will lock translation in the Z direction relative to the Normal orientation, pressing Z again will lock translation to the Z axis relative to the Global orientation. Pressing Z again will remove all constraints.
How does plane locking affect translation and scaling?
Plane locking only affects translation and scaling. Note that for rotation, both axis and plane locking have the same effect because a rotation is always constrained around one axis.
Which is brighter locked axis or unlocked axis?
A locked axis will display in a brighter color than an unlocked axis. For example in the image to the right, the Z axis is shown in light blue as movement is constrained to this axis. This example, can be achieved in two ways:
Can a trackball be locked to an axis?
Trackball type rotations R R cannot be locked at all. A single key press constrains movement to the current transform orientation selection. A second key press of the same key constrains movement to the corresponding Global axis (except if the transform orientation is set to Global, in which case the Local orientation is used).
How to rotate an object on its local axis?
Ahh – seems RotateAroundLocal rotates around the PARENT’s local space… This moves the Vector3.up from local to world space. The you rotate around THAT in world space. This will work no matter what your parenting seetup is. It’s still not working. Turns out this is a bug in RotateAroundLocal.
How to get distance from object SNAP point?
After you acquire an object snap point, use direct distance to specify points at precise distances along alignment paths from the acquired object snap point. To specify a point prompt, select an object snap, move the cursor to display an alignment path, then enter a distance at the prompt.
How are objects affected by forces without contact?
Some objects experience forces from things that are not touching them. Magnets can be used to make other magnets and things made of iron move without being touched. Something that has been electrically charged can make other things move without touching them. Things near the Earth fall toward the Earth unless something holds them up.
What happens when Forces Act at a distance?
The main notion to convey here is that forces can act at a distance with no perceivable substance in between. Through their investigations, students can show magnets do not affect all metals but can push or pull other magnets and things made of iron (and steel).
