Command:Link to Spline
The easiest method to attach a "Vertex" to a specific position along a "Spline" is to create a new "Vertex" at that same position.
In general this method works, but is not very effective. In fact it has at least two drawback. First, it increases the complexity of the drawings. Secondly, it is not possible to move the attached vertex along the "Spline".
The "Link to Spline" feature provides an easy way to attach a "Vertex" to a "Spline" without the necessity to create an additional "Vertex". Once applied, the "Vertex" will be bounded to the "Spline" and will be possible to place it arbitrarily along the defined path.
To link a "Vertex" to a "Spline" you can:
- Select the "Vertex" you want to link and the target "Spline"
- Select the handle you want to link to target "Spline". It could be:
- a "Vertex" handle
- a "Tangent" handle
- the Origin of a Group Layer
- a "Real" handle
- Right click on the target "Spline" and select "Link to Spline"
- if a "Vertex" handle is selected, it will be placed on the "Spline" at the clicked position
- if a "Tangent" handle is selected, it will be linked at the clicked position
- if the "Origin" is selected, it will link both Origin and Angle parameters
- if a "Real" handle is selected, it will link with the Spline width at the clicked position
- NOTE: At step 2 you can select more than one type of handle at the same time and link their values to the same position of the target "Spline".
Inverse handle Manipulation
It is possible to change the linked handle position along the "Spline" simply by dragging it. If you linked the Tangent and Origin, you will notice what they are changing their values according the value of the target "Spline".
You may also specify their Offset simply by dragging them, i.e. making tangent 90 degrees to Spline will keep that Offset at any point of the "Spline".
