Clip

Hi everybody!

I have a problem with the 'Clip' tool, in the Editing toolbar.
I am editing polygons, of different landscape types.

When I edit for example agricultural polygons, then sometimes other polygons overlap with agriculture (f.e. plantations). When I select the agriculture-polygon, and I click the 'clipping' tool, then the area of the onderlying polygon with which agriculture intersects, disappears.
(agriculture lies above other landscape-polygons)

Unfortunately, this doesn't work for every landscape type.
When I edit plantations, then I see it lies beneath f.e. a grasland-polygon. When I select the plantation-polygon and I click 'clip', the area of grasland with which it intersects doesn't want to disappear.
And sometimes, there appears a message (but not always), saying: "could not clip any features. There are no features coincident with the selected feature", although this is not true, because it IS coincident with another feature, namely the grasland polygon!
(I think the problem lies in the fact that in this case, plantation lies beneath grasland? OR: because both shapefiles, or located in different maps on my computer?)

And strange enough.. I can not edit grasland-polygons. I can select them, but I can't edit them..

Does anyone know what's going on?

Thank you in advance!

This problem is already solved. 😉

I put both shapefiles (plantations and grasland) in 1 single folder on my computer. I connected to that folder within ArcCatalog, added the data in ArcMap.
When I selected the plantations-polygon, and I clicked 'clip', then the underlying grasland-polygon that was intersecting with it, disappeared!

But.. was this the problem?
Does the shapefiles really have to be inside one an dthe same folder?

Yes, you can only edit a single 'workspace' at a time, in the case of shapefiles the containing folder stands in for the database. If you have shapefiles from multiple folders (or FCs from multiple databases) in your map Start Editing will ask which workspace you want to edit.

It is not possible to clip an unsaved polygon. Saving your edits before clipping will solve the problem.
