To Merge AEC Polygons

Use this procedure to merge two or more AEC polygons in a drawing. When you merge two AEC polygons that overlap each other, their common boundary is combined to form the boundary of the merged AEC polygon.

Note: When you merge one AEC polygon with another, the properties of the merged AEC polygon are identical to the properties of the first selected AEC polygon.

1. Create two overlapping AEC polygons.
2. Select one of the AEC polygons to be merged.
3. Click AEC Polygon ribbon contextual tab Modify panel Merge.
4. Select the AEC polygon to merge with the first AEC polygon.
   Note: You can merge only those AEC polygons that lie on the same Z-plane. Two AEC polygons with different Z-positions in the same coordinate system cannot be merged.
5. Enter y (Yes) to erase the second AEC polygon, or n (No) to leave the AEC polygon in the drawing.
