3D-Scale Problems - Cannot Select individual Axis.

Hey guys, I'm working on a SIMPLE 3D project. I'm trying to scale in the Z axis a box I drew, but the scaling "GIZMO" is restrained to all three axis, I cannot select individual axis no matter what I try. I really need help guys.

Workarounds are to make a block to scale, then explode the block if preferred to forget about it later:

If you drew it using the BOX command specifically, then you can change the height in the Properties palette:

If you drew it by [for example] EXTRUDEing a rectangle Polyline or PRESSPULLing in one, then you can't do it that way, but you can grip-edit the height of it in 3D view [which you can also do with one made by BOX].

In any of those cases, the (getpropertyvalue)/(setpropertyvalue) method can be used to change it, and an AutoLisp routine could be defined that would calculate and impose a new Height value for you, based on the current value and your desired scale factor.

If you want to Scale it by a specific factor without such an AutoLisp routine, not knowing what that's going to mean in terms of a new Height value or a grip-editing distance, then define it into a Block, and change its Z scale factor.

There would be cases where only the define-as-Block approach will work, such as if it is the result of a SLICE command.

Depending on what you have and what you want to achieve (both we don't know) also the SOLIDEDIT... command perhaps can help you to reach your goal.
