A Clone in Vexy Lines is a unique copy of an object. When you create a clone, it retains certain properties from the original object. If these properties are modified in the original, the clone will automatically update to reflect those changes.
However, while the clone maintains some shared properties with the original, it can also have independent attributes. For instance, if the original object has lines set in a specific pattern and you adjust their direction or spacing, the clone will adapt accordingly. But attributes like color or line shift in the clone can be altered without affecting the original. This allows for a balance between uniformity and customization.
Clone with changed color.
Clone with changed dashes.
Clone with changed image threshold.
In Vexy Lines, only the following fill types can be cloned: Linear, Wave, Circle, Spiral, and Handmade. For other fill types, a simple copy of the object will be created.
