When I just started with ZB this hint was very useful to me:
If you know the IMAGE PLANE tool you know how easy it makes it to place, rotate, and scale image planes. However, it does not allow such comfort with other tools like spheres etc.
Sometimes also the desire arrises to place, scale, rotate things with an absolute value. There is no ‘obvious’ way to do it but there is a way.
If you are NOT in ‘T’ (edit) mode but in Move, Scale, or Rotate mode, then you can enter values in the X,Y, or Z component blocks and your object will rotate, scale, move according to your absolute entries.
In any case, the values are always updated in realtime and for me that’s often very useful even if I do not change them manually.
One thing to remember regarding the scale figures is that they count from the center and thus are to be thought of like a radius rather than a diameter. My 800x600 sample has the size entries 400x300 because of that.
It’s a nice, but well hidden function:D.
