Hello community,

 

after extending a blend between 2 parallel lines,

my eraser turns these straight lines into wobble lines.

 

Does anyone know a solution to this problem? Would be much appreciated.

    I finally found a good solution!

    You just need to make the canvas bigger ( 2000x2000+ ) it will add anchor points here and there, but most of the times it works now.

    Thank you everybody for your participation.

      In AICC2017 and Sierra 10.12.6, I'm unable to reproduce the wobble. I make a blend of two paths (no fills), expand the blend (Object>Blend>Expand), then use the eraser (shift-E) to remove segments at random angles. My resulting path segments are not distorted. What am I missing?

      Use the direct selection tool and drag a selection rectangle over the paths. Then you should see additional anchor points and handles on formerly perfect straight lines.

      "of course you get additional anchor points"

       

      Sure you get them. Eactly at those points where you cut the lines, but you shouldn't get them anywhere else. But that is what is happening. And it has always happened since the eraser tool has been added.

       

      This is Illustrator CS4:

       

      And don't you dare and zoom in, because, no, those handles are not straight:


      I don´t understand why adobe wouln´t fix that since adobe cs4...

      I understand that there are specific tools from adobe to draw, but i really enjoy working and experimenting with the blend tool, especially that you can change the strokes afterwards.

      Since you don't want to outline strokes, I would suggest you draw the shape that you want to erase, fill it with a different color than the stroke color and then apply the pathfinder "Outline". The part you don't want, can be selected by stroke color and then deleted.

      Unfortunately that is a known issue.

      Can you give us the big picture of what you want to do?

      Thank you for your fast reply.

      I want to shade using parallel contour lines, be able to erase parts ( in this case the top of the ball )

      and be able to edit every single line after i´ve cut them. for example make them tapered etc. .

      I used now the brush in the same colour as the background to simulate it.

      I have a course on this drawing technique and many people on there have this issue... but as my tutor is doing the exact same process, it works for him. Unfortunately the course is too old, for him to respond anymore....

      I get similar results with stroked paths.

       

      If I outline strokes (as you would need to if you want to achieve your second image) I get rather less noticeably bad results, but its still apparent.

       

      Haven't noticed this bug before.
