Merging Paths

Multiple
can be merged into a single
using the menu item Transform->Merge Paths. Note that this is not the same as |
|. Moves (gaps) will be placed between the last
of one path and the first control point of the next path. Once the path has been merged, it can then be edited. If the paths had different styles, the new path will retain the style of the first path (the lowest one in the
). For example, in Figure 8.25(a) there are two paths with different styles. Figure 8.25(b) shows the single path created from merging the two original paths. Since the first path used the even-odd winding rule, the new shape has a hole in it.

Figure 8.25: Merging two paths: (a) the first path has a solid line pattern, a green fill colour and even-odd winding rule, and the second path has a dashed line pattern and a yellow fill colour; (b) resulting merged path has a solid line pattern, green fill colour and even-odd winding rule.

The same applies if one or more of the selected objects is a
. For example, in Figure 8.26(a) there are two text-paths. These are merged to form a single text-path shown in Figure 8.26(b). Note that the text from the second
is lost. The resulting path is shown in edit mode in Figure 8.26(c) to illustrate the underlying path. A mixture of paths and text-paths can be merged. The resulting object will be a text-path if the first object to be merged is a text-path, otherwise it will be a path.

Paths are merged according to their
. For example, in Figure 8.27(a) there are two paths, both with a bar start marker, and an arrow end marker. The path on the right is further back in terms of the stacking order.8.4 Figure 8.27(b) shows the result of merging the two paths--the left hand path has been appended to the right hand path. Figure 8.27(c) shows the same two paths as in Figure 8.27(a) except that now the left path is the
. There is no visible difference between Figure 8.27(a) and Figure 8.27(c), but the result of merging the paths in Figure 8.27(c) (see Figure 8.27(d)) is different to Figure 8.27(b)--the right hand path has been appended to the left hand path.
