cutting compound paths

cutting compound paths

cutting compound paths

Well, I can't do it. I've gone round and round in circles and found nothing in 'help' - so I turn to the experts!

I have drawn a grid made up of many vertical and horizontal lines, and want to chop a smaller section out of it (because the squares ore too small.

Does anyone know how I can do this - other than using the scissors on individual paths??

RE: cutting compound paths

...select grid of strokes (release the compound if it is already is a single compound shape by choosing object > compound path release)...

...choose object > expand, click OK...

...your grid is now outlined paths as opposed to strokes...

...with entire grid still selected, choose object > compound path > make, this is now one compound object...

...draw cutter shape above grid...

...select both the compound grid and the cutter  shape needed to "cut" a larger hole...

...choose the pathfinder palette (window > pathfinder), select the "minus front" option...

...in CS4, if you hold down alt/option key as you choose the "minus front" option it will keep the object "live" meaning you can adjust the hole shape later if required...

...in lower versions i believe this is the opposite, in that using the alt/option key makes the shape "complete"...



RE: cutting compound paths

Thank you Andrew ...... I wouldn't have worked that out in a century!
(Except by accident......)

RE: cutting compound paths

...haha!!! a century?

: )

...i've just turned 150 and i only found out by accident...

: )

...anyway, the golden rule is that a stroke has to be converted to an expanded shape, otherwise the pathfinder functions will give you odd looking results (unless you want an odd result)...

...the compound function is also required so illustrator knows the lines both horizontal and vertical need to be cut through, so it has to be one object...

...or you end up having to perform a pathfinder function more than once...


RE: cutting compound paths

Andrew ... I expect you're a genius of some sort.
Thank you for your valuable advice!

RE: cutting compound paths

...thats fine john glad to help sir!

...one other grid tip i can also provide is in the creation of grids, in many cases it can be easier to just split a primitive rectangle that has only a stroke color applied (no fill color set to none if you wish to have it transparent) by using the object > path > split into grid, set the gutter value to zero and dial in as many rows as you like, do the same values for the column section...

...creating a grid this way also enables you to change it later down the road by simply selecting the whole grid object and going back to that dialog again (object > path > split into grid)...

...obviously once you "expand" an objects structure it loses it's "live" editing capabilities...


RE: cutting compound paths

OK, thanks Mr Ape PP (!).
I've saved you advice in a folder for th future when I've forgotten everything.

Much appreciated.
