I have a large data set that spans all of California but only a small portion of this needs to be part of the map I'm working on. Normally I would use the Intersect command to clip away everything outside my work boundary.

Is there a similar work flow with MAPublisher and Illustrator that will clip all of the polygons to within another boundary polygon? The results would look just like a clipping mask of the larger data set but there would not be any hidden polys, everything is actually physically clipped to new shapes that conform to the clipping boundary and retains their attributes.

There's the Map Vector Crop tool, it'll let you drag a box around the features you want to keep and removes everything else. Also, MAPublisher 8.3 offers spatial selections, so you can select all features from layer A that fall within the feature(s) on layer B. That won't intersect, only select, but it'll still help you a lot.

For a non MP solution - there is also the trim and crop functionality in the Pathfinders palette.

one quick note ... If you use any of the pathfinder tools to any GIS objects in AI-MP, you will loose the attribute. :(

I use the Map Vector Crop to clip map layers to the frame extent frequently but for clipping to smaller boundaries inside the frame I prefer the neat results of an intersect. I'm surprised Avneza doesn't have this in MApub. Maybe as a future development.

I have so far had little success using the spatial selections tools in MAPub but I'm sure thats because I haven't read the "how to" yet. This may be a better way to reduce the layer size before using a mask.

Or I can Intersect the data on Monday when I get back to the office. This is probably the most frequent use I have for ArcGIS in my freelance work, I really wish I could do it in Illy.
