I was thinking that some kind of bend tool would be kind of neat. I'm not sure if there is a place we're supposed to put suggestions, so I'm just putting it here. Here is my suggestion about how you might choose to implement the tool. A.
First you have some "clay" that you want to bend. In this case it's just represented as a bar, but it could be any shape.B.
Next you would take the "Bend Tool Area Selection" and paint a transparent selection (green) over the area you want the bend to take place. So the bending only happens to the portion of the clay that is encased inside the selection.C.
Next you place your pivot point (red) inside of the transparent selection. This point represents the apex of the bend.D.
Finally you 'grab' the clay on the outside of either side of the selection area and then move your hand to bend the clay in the direction and angle of your choice. The clay within' the selection area is bent (stretched or compressed as necessary) while the areas outside the selection remain normal. Which ever side you do not grab becomes the "anchor" and remains in place during the bending process. If you leave the selection and pivot in place after performing the bed, you could grab the other side of the clay and bend that as well without having to create a new selection area and pivot and the other side of the selection would automatically become the anchor.
Thanks for your time. I hope this suggested feature request is useful to you or inspires you to come up with a better way of doing it.
Keep up the great work! This is an amazing piece of software and something I've been dreaming about having and thinking about for over 25 years!
