Hi. This seems like a rather simple and important fix. To me anyways.
There are certain shapes that you cannot make as the engine is set up now. For example, a rectangular prim of any length with a width and height on one side of 0.01x0.5 and on the other side 0.3 x 0.3. Go ahead try.
Oh wait. You can't.
In order to do this You either need a "Bottom Size" or you need to be able to set "Top Size" to a value greater than 1. This seems to be a hard coded limitation that could be easily adjusted. Either solution would allow the above said shape to exist. I happen to need said shape. And it's a simple piece of geometry that I should be able to create. Anyways, I hope to see this soon. Thanks for your time.
