Getting the most out of the Vector tools in Expression Design.

Monday, May 04 2009 - Resources

This post is planned to help you create great vectors and get the most out of the tools you have in Expression Design.

Here is 2 simple shapes I am going to use for the examples, with a
blue gradient, corner radius of 20px and a stroke thickness of 5px

Compound Paths

Compound paths take the existing paths and find the overlapping
sections and remove them (the paths are un-altered but the shape is
merged).

How to: Select both shapes and go to Object > Compound Path (or just hit ctrl+8)

Clipping Paths

Clipping paths remove anything that is outside the selected “clipping path”.

I have turned the top shape into a clipping path (by top shape, I am
refering to the layers, not the location), so it deletes any part of
the bottom shape that is outside its path, when you create a clipping
path you are given the option on which path you wish to use as the
clipping path.

How to: Select both shapes and go to Objects > Clipping path  and
select if you want to top or bottom shape to be the clipping path, you
can also release a clipping path from here.

Intersect

Intersect is very cool, all it does is find the overlapping sections of the 2 objects and keeps it, then deletes the rest

How to: select the 2 objects, go to Objects > Path Operations > Intersect

Divide

This takes each section of the paths and “divides” them into parts.

 This is cool if you wanted to explode the object.

How to: Select the 2 objects, Object > Path Operations >
Divide (to detach each section just select each part and move as if
they were separate objects)

Unite

Unite simply makes the 2 objects one. Removing any overlapping sections.

How to: Select the 2 objects, Object > Path Operations > Unite

There are 2 other options in the Path Operations menu which are:

Front minus back and Back minus front

These items simply remove one object from the other.

How to: Select the 2 objects, Object > Path Operations > Front Minus Back (or Back Minus Front)

And last but not least… the Envelope distort tool…

This doesn’t need 2 objects to be done, but it will work with multiple objects selected…

This will create a grid over your object, and using the Direct Select tool you can manipulate each point in the grid for some really cool effects!

How to: Select you object/s and goto Object > Envelope Distort, then use the direct selection tool to manipulate each point.

Hopefully with these tricks you will be able to get the most out of Expression Design and create some really interesting stuff.

Thanks
