Editing segment parameters

- Let's start looking at the most basic parameters…of a segment.…I'll select the Trunk node…and in its parameters we've got the Segment tab here…and the Length is the most primary aspect…of a segment.…And right now, we have a length of ten units…with the default units of meters…And we can see down here that the Z dimension,…or the elevation, is 10.2 meters.…So there's a little bit of a fudge factor there.…

It can vary slightly from this value.…We can also see the height…by clicking on this ruler button here.…And that's on the Advanced display options toolbar.…Click on Show Ruler…and we can always see the scale of our plant…with that ruler.…Let's give it a length of six meters…and also vary that length a little bit.…Next to some of these fields here,…we have a plus or minus field.…And that will randomize the plant variation,…depending upon the seed value.…

If I give it a value of 0.5 here…and press Enter,…now we have a length of six meters…plus or minus 0.5 meters.…And each time we click…on the new plant variation button here,…
