Basically, what clipping in inkscape does, is takes the top path in a selection and clips all the paths below it (in the selection) to the shape of the top path. Confused? Let me walk you through a simple example:
1. Draw some simple shapes.
2. Now draw your clipping path. (mine is a pink star)
And make sure this path is on top of all the other objects/paths
(dont worry about colour, after the clip this path will not be visible)
3. Select all the paths now, and go to Object > Clip > Set. You can see the result below.
So how does this tie in to the orb tutorial i did before? I have done a simple example of the workflow again. (this time only the clipping part of the tutorial…)
