Command:Link to Spline
Generally if you want some vertex to be attached to some point on another BLine, you need to create a vertex at that point on the target BLine. That increases the complexity of your image and has a drawback - you cannot move the attached vertex along the BLine.
The Link to BLine feature provides an easy way to attach a vertex of a BLine to another BLine without the creation of an additional vertex. The vertex becomes "stuck" to the BLine and can be moved along it.
- Select the bline you want to link and target bline
- Select the duck you want to link to target bline. It could be
- bline vertex duck
- bline tangent duck
- or real duck
- Right click on the target bline (not the bline vertex!) and select "Link to BLine"
- if selected vertex duck, it placed on bline at position where clicked
- if selected tangent duck, it links with bline tangent at click position
- if selected real duck, it links with bline width at click position
- NOTE: At step 2 you can select bline vertex, tangent and real ducks at the same time to link their values to the values on the same position of target bline.
Inverse Duck Manipulation
It is possible to change linked duck position along bline simply by dragging it. If you linked the tangent and width ducks too, you will notice what they are changing their values according the values of bline.
You may also specify the offset of the tangent and width ducks simply by dragging them. I.e. making tangent 90 degrees to bline will keep that offset at any point of bline.
