I'm trying to make a pattern whit the tool in illustrator, but I'm not able to erase lines inside the pattern. Why doesn't the eraser tool work inside the pattern tool?
i have taken the question to mean that artwork that has a pattern brush applied to it is in use. this artwork appears to retain lines (with pattern brush applied) after the erase tool is applied on the said paths. solution would be to break the closed path(s)
Sorry for being unclear, What i meen is that inside the pattern-tool I can't erase anything with the eraser-tool. I can use the eraser without problem on any objekt outside the tool but once I go " Object > Pattern > Make", the eraser-tool is disabled.
OK. You won't be able to change that.
Use other tools. e.g. the blob brush (it acts like the eraser) and then later subtract shapes via pathfinder.
Or use the pen tool, direct select etc. to correct your paths.
