Dear All,

As my [demo](https://jsfiddle.net/jxnx888/e630ufcv/50/), I set transform controller limitation in` scale and translate mode`. Objects cannot move out of the workspace.

So there are two issues that occurred.

First, I always check the position to give the limitation. Is that ok? or if there is an alternative way to do it because If the objects are not `Geometry`(such as an STL object), I cannot set the default size as 50 like the `Geometry`;

Second, If I rotate the object, it still can rotate the object out of the workspace, how can I check it?
