Add stroke to internal lines in mesh objects
I am trying to create a fishing net in adobe illustrator. I have created an ellipse object and created the mesh but adding a stroke via the appearance panel only does it to the border of the mesh object not the internal lines (see the picture below). How can I add a stroke to the internal lines to create a net appearance? If this is not possible with the mesh tool how would you create a net in illustrator?
Mesh lines are not actual paths. You can not stroke them like other paths. Mesh lines are for construction.
If you wish to have a grid of lines, you need to create that grid. Then you could use a mesh to transform, distort, and otherwise alter the grid. The easiest way to create a grid of lines is by using the Rectangular Grid Tool.
While dragging with that tool the up, down, left, and right arrow keys will increase/decrease the amount of grid sections.
