I’m designing a heater and I’d like to create a custom perforated pattern in the front panel. The pattern will be based on an image of a flower or similar.
I’d like to create the pattern using circular holes of varying position and size.
Does anyone know of a filter or tool in illustrator that can accurately overlay a series of vector cirles over the top of an image? I can do it the slow way but I thought someone may know of a short cut.
I’ve seen some examples on the web where people have done this. The example below is close but I’d like all of the holes to be circular.
OK, Thanks. I’ll give it a go.
The live trace doesnt seem to produce exact circles but it gives me a great layout to then place the circular holes manually over the top.
The panel for this heater will be perforated during the blanking process. Since the manufacturer would put a normal perforated pattern into the tool anyway I’m pretty much getting this pattern for no extra charge. (maybe a slightly higher tooling set up)
Same question posted on the Adobe forum with a solution:
I tried the solution and it worked, but they’re still approximations of circles. I think if you made sure that your rasterized halftone was high enough rez, and looked like perfect circles, you could get what you need. Be sure to play with the Live Trace settings in Illustrator. Keep “path fitting” low.
Another solution is similar to richard’s. Start by making your dot matrix, then overlay your solid flower pattern on top. Create a clipping mask with your flower pattern (needs to be vector) and your done.
there is a program out ther called rastebator (great name) that takes any .jpeg, runs it through their filter and outputs a .pdf scaled for A1 size paper,that is all circles of varying diameters. I used it to create stencils of relatively detailed scenes to paint on a wall, but it could probably do what you want. I believe that there is a downloadable application that allows you more control, but it is pc only and I havent had a chance to use it:
