Is there any possibility to create a Null Object with a custom dimensions via a script?

I don't mean that it has been scaled down, but that the actual layer gets created with custom dimensions, like 62.5, 62.5

I hope this is possible.

Dimensions on a null are meaningless. The anchor point is at 0, 0, 0 and nulls don't render. Their size does not translate to other layers unless you add an expression that reads the height and width of the layer. I'm not sure what purpose setting a custom size for a null would have.

You can do it with a script, but you need to modify the null's source, and the width and height have to be integers. So you could do something like this:

var myComp = app.project.activeItem;
var myNull = myComp.layers.addNull(myComp.duration);
myNull.source.width = 63;
myNull.source.height = 63;

I actually wanted to use it as a spacer for a grid like layout.

But I just discoverd I can also do this with slider expression controls.

But thank you for your awnser anyway.
