Function Description

With the Shatter function, you can break up the selected single or multiple line objects into the smallest unit of line objects.

The line object of the smallest unit indicates that the object has only two nodes, that is, two endpoints, and is a simple object.

As shown in the figure below, there are five nodes in the object to be shredded (Figure 1); after the object is shredded, it is decomposed into four objects, and each object contains only two nodes. Fig. 2 shows the result of making a Unique-values Map according to SMID for a plurality of objects after explosion.

• The Shred feature works on 2D line layers as well as CAD layers, and is available when the layer is editable and the line object is selected.
• Complex objects are also suitable for shredding operations. The exploded complex object will be decomposed, and each sub-object will be decomposed into the smallest unit of straight line.

Function entrance

• Object Operation tab-> Object Editing group drop-down box-> Shredding.

Operating instructions

1. In the layer editable state, select one or more line objects to shatter.
2. On the Object Operation tab, in the Gallery control in the Object Editing group, click the Shred button to perform the shred operation.
3. After the shred operation is completed, you will be prompted in the Output Window how many objects will be generated after the shred. For example, the line object smID = 221 was blown up, resulting in 4 objects!

Caution:

Objects with many nodes such as

arcs and circles will not be displayed at a small scale because each segment of the newly generated object is relatively small after explosion. Application filters and displays some small objects. Line objects with a length less than 0.4mm are not displayed. For information on the minimum size of objects, see the Object Size Filter Display section of Map Display Optimization.
