Auto-Split Line object

Function Description

The Auto-Split Line function is used to automatically split the original object and the newly drawn line object at the intersection position and generate multiple line objects at the same time during the Draw Line Objects.

  • The Auto-Split Line object works with line layers or CAD layers.
  • The operation process of Auto-Split Line is shown in the following figure.

    Draw the line object that intersects Figure 1. Figure 2 and Figure 3 compare the results with and without the Auto-Split Line object.

    Figure 1 Draw Line Objects. Figure 2 Non-automatic interruption Figure 3 Automatic Break Result
    The

    original line object (line 1 in Figure 1) is deleted after it is broken, and the System Field: (except SmUserID) of the new line object (lines 3 and 4 in Figure 3) generated from it is assigned by the system. Non-system Field: and the field SmUserID retain the corresponding attributes of the original line object. The Attributes of the newly drawn line objects (5 and 6 in Figure 3) are added to their attribute tables in the order in which they were drawn.

  • If a drawn line object intersects a complex line object (the original object), that is, a line object with multiple sub-objects, the newly drawn line object is broken at the intersection with the Auto-Split Line object on, and the original object is still a complex object, but a new sub-object is created at the intersection. You can select the object, right-click, and view it in the Properties dialog box.
  • If you paint a new object that does not intersect any line objects, the Auto-Split Line object is not turned on, and only the painted object remains.

Function entrance
