    Redrawing Complex Vectors

    rorys64395165

      Hi guys,

       

      I'm having a problem which I'm hoping is fairly basic and easy to answer!

       

      I have drawn quite a complex black and white 2 colour drawing by overlaying a fair few vector objects on top of each other.  However, I now wish to manipulate this drawing in such a way that I can easily change the colour of all of it, by clicking on the group, and selecting a new colour.

       

      However, when I do this, it changes the colour of all of the objects, including some which I wish to remain white.

       

      I realise that this has been caused by me being lazy and not intersecting objects correctly and using the Pathfinder, but what I'd like to do is get Illustrator to dedraw this vector image as one item - i.e. so all of the objects that currently show up as black remain black, and those that are white are white.

       

      This may not be very clear, but one workaround I've been using so far is to export the black and white image as a hi-res PNG, then reimporting it and doing a Live Trace.  In effect I am after exactly the same procedure, but avoiding the clumsy situatioin of losing quality by going Vector > Raster > Vector.  Instead can Illustrator do a straight redraw from the original vector objects?

       

      Thanks,

       

      Rory.

          I would use the magic wand to select all the black items, fills and strokes, Expand, then Pathfinder Unite. If you double click on the magic wand you can set tolerences for fills and strokes. Since I don't have your artwork in front of me I can't tell if your artwork has both strokes and fills creating the black.

            Thanks - I've attached the artwork.

             

            In effect I'd like the car to all be one black object and all the white (including the heads etc and headlamps etc) to be transparent - in effect the same as tracing it in raster.

              You have to clean up the drawing, for me is more easy to show you than to write and explanation, so see attached your file corrected,

               

              I have used the pathfinder / unite in some parts and finally a compound path from the object menu

                You need to remove some of the superfluous Cra… stuff in the art. Then you can use the magic wand set to zero tolarance fill to select one of the head lights and Pathfinder Unite. Then select the black area and Pathfinder Unite. Then select all and use the Pathfinder Minus front.

                 

                Here is an image of what superfluous stuff could be removed to make the image more manageable.Picture 6.png

                  Hello Rory,

                   

                  PrepressPro1 is right about using the "Magic Wand". However, after I opened the Ai file I noticed 2 problems with the artwork.

                   

                  1) The files contains 2 types of black

                  2) We have 2 Strokes of 21.595 point

                   

                  To solve the first problem, select all white areas using the "Magic Wand" (just like PrepressPro1 said) and hide the white areas (Main Menu: Object + Hide + Selection). Now all you can see all the black areas.

                   

                  Select all and use Pathfinder Shape Modes "Add" (Please note that in CS3 this feature does not work if select it from the "Effect" menu)

                  (Main Menu: Window + Pathfinder) From this window apply "Add" and click "Expand"

                   

                  With this last operation with have deleted the 2 Strokes of 21.595 point and we have 2 half circles. Cover those 2 half circles with black squares and repeat the Pathfinder option.

                   

                  After these steps now you have one single black object.

                   

                  Now lets bring back the white areas (Main Menu: Object + Show All) and bring them to the front (Main Menu: Object + Arrange + Bring to Front)

                  With the white selected, we have to compound them (Main Menu: Object + Compound Path + Make)

                   

                  Now select all and use Pathfinder "Subtract" and click "Expand" and you are done.

                   

                  As you can see the vector file that you received was wrong, and this type of files can produce problems during the printing process. However, if you fix files like this, you will avoid problem with the pre-press department and you will have more control of the artwork.

                   

                  I hope this helps!
