How do I change the size of arrow heads?

[bnlove]

I see how to change the width of my line, but can’t figure out how to change the size of the arrow heads at the ends. I know in some version of omnigraffle I could do that, but can’t figure it out now.

Thanks.

You can’t change the line end size independent of the line stroke, but you can attach multiple lines so that they can each have a different stroke size. By that, I mean this is an example of a 6pt straight line at the end, attached to a 1pt line.

Will that work for what you are trying to achieve?

Thanks,
