XView is another of those 'would be useful if it was finished' features. Here's the list of what I'm missing and why I don't write my own xView checkers:
- XView 'supports' selection of multiple objects at the same time but when you do that their highlight lists will get merged and you will get misleading and useless selections. In effect, you can only use XView with one object at a time, losing big part of its potential usefulness
- XView will let you work with primitives but won't display anything unless you add some modifier that changes the stack result to mesh/polymesh. You can collect your edges/faces you want to highlight and it will display the correct number but that's it…
- XView lets you configure colors - but you can only have one color at a time, and only one checker/highlighter at a time. That means that all the tension/map distortion/face area/SGs visualisations used etc are impossible to do. It would be much more useful if you could supply another array of colors for the elements to be highlighted.
