And

Input: One or two DV layers (containing polygons)

Output: DV layer (containing polygons)

Description: Creates and returns a DV layer that contains geometry generated from the overlap of original geometry on the input layer(s). This is a symmetric operation. The order of the input layers does not change the results.

• Single input layer functionality uses raw (unmerged) geometry so that overlaps are not removed.

• Two input layer functionality merges geometry of input layers that are imported. In the following example the two rectangles on layer A are merged into one polygon before doing the And operation. The result of the And is one polygon.

• If the input layers are not imported (they are created within DV), two input layer functionality uses the geometry “as is”. In the following example the two rectangles on layer A are not merged before doing the And operation. The results of the And are two overlapping polygons.

Rule Set Example (JScript):

var layer1 = DVChecker.ImportLayer("trace");

var layer2 = DVChecker.ImportLayer("ground");

var andLayer = DVChecker.And(layer1);

var andLayer2 = DVChecker.And(andLayer);

var andLayer3 = DVChecker.And(layer1, layer2);
