Shape & Mask Paths

General tips
Maintain stroke width
// from campkeyframe
sf = transform.scale[0]/100;
 ov = value;
nv = ov / sf
​
// for parented shapes 
value / length(toComp([0,0]), toComp([0.7071,0.7071])) || 0.001;

Looping paths (loopOut() doesn't work for paths)

Accessing Shape parameters
Shape Property Group and Index
// shape group index
thisProperty.propertyGroup(2).propertyIndex // change num accordingly
​
// using name as index eg. line_1
parseInt(thisProperty.propertyGroup(3).name.split("_")[1]); // method 1
parseInt(content(1).name.split("_")[1]) // method 2
