Function Description

The Auto-cut Polygons function is used to automatically split the intersection when drawing a region object, and obtain a new object. The new object may be a single object or a complex polygon object.

• The Auto-cut Polygons function is applicable to polygon layers or CAD layers.
• If the newly drawn object intersects with other objects in the layer, it will automatically cut the newly drawn object, removing the intersecting parts, and obtain a new object.
• If the newly drawn object does not intersect with any object, the Auto-cut Polygons function will not be triggered, and the drawn object will be retained.
• If the newly drawn object passes through an existing polygon object, it generates a complex polygon object, i.e., a polygon object with multiple sub-objects. As shown in the figure below, the newly drawn polygon object (dashed rectangle) passes through another polygon object (filled rectangle), resulting in a complex object containing 2 sub-objects.

Function Entry

• Features tab -> Objects group -> Drawing Settings drop-down menu -> Auto-cut Polygons.

Operation Instructions

Figure 1 Drawing a Rectangle

Figure 2 Drawing a Rectangle After Cutting

Figure 3 Cutting Result

1. In the Features tab's Objects group, click the Drawing Settings drop-down button, and select the Auto-cut Polygons option from the drop-down menu; or use the Shift+R shortcut key to enable the Auto-cut Polygons function. To disable the Auto-cut Polygons function, click the option again.
2. In the current editable layer, draw a polygon object. As shown in Figure 1, draw a rectangle (represented by a dashed line).
3. If the drawn rectangle intersects with the other two rectangles in the layer, the drawn rectangle (dashed rectangle) will be cut by the other two rectangles, resulting in a new object, as shown in Figure 2.
4. Move the obtained new object, as shown in Figure 3.
5. To disable the Auto-cut Polygons function, uncheck Auto-cut Polygons.
