Accessing lines, arcs, etc in a sketch

[R-man]

A couple of questions:

From a script can I list all lines (for example) in a sketch, and get information about them?

Can I name a line when I add it to a sketch and then refer to it by name to get info?

Yes you can. You can do something like this

MyPart = Part('My Part')
MySketch = MyPart.AddSketch('SomeName', MyPart.XYPlane)

p1 = [0, 0]
p2 = [0, 10]
p3 = [10, 10]
p4 = [10, 5]

line1 = MySketch.AddLine(p1, p2, False)
line2 = MySketch.AddLine(p2, p3, False)
line3 = MySketch.AddLine(p3, p4, False)

MySketch.AddDimension(line1.Start, line1.End)
MySketch.AddDimension(line2.Start, line2.End)
MySketch.AddDimension(line3.Start, line3.End)

result = MySketch.AddConstraint([line1],Sketch.Constraints.Vertical)
print(result)
result = MySketch.AddConstraint([line2],Sketch.Constraints.Horizontal)
print(result)
result = MySketch.AddConstraint([line3],Sketch.Constraints.Vertical)
print(result)

That is exactly what I needed to know. Thank you!

How about getting information about lines etc. For example is there something like lineLen = line3.length ?

Yes, AlibreScript has an ability like that. I suggest checking out the quick start, reference/help files, and examples found in the AlibreScript menu.

Thanks Nate - I've never bothered much with the reference because the terminology is alien to me, but after an hour or so of making the effort I'm finding my way around. Good advice!
