Hi,

Just started playing with DD and have found an issue that seems like a limitation. I have created two squares and am attempting to animate one square sliding along the side of the other. I have created a Distance constraint between the ends of the squares perpendicular to the sliding edges and am animating that distance, but it seems that distance values can only be expressed as positive numbers, where movement in the positive direction (in X) is from right to left, which is in the negative X direction.

Is there a way to specify the direction of movement?

Hi Terry,

Currently we do not support negative distances. We'll take your opinion into account while preparing next releases.

In any case, negative values can be supported only for distances with planes, it can not be naturally supported for edges
since we are in 3D.

As a general solution I can propose you to create a third fixed plane and measure all the distances from it.
In such a way you can easily obtain an animation of the side of the first square going across the side of the second square.
If I'm not very clear please share your model, we can try to modify it to achieve the desired behaviour.

Best regards,
Alexey
