Weld

Use this action to combine a group of graphics in a manner that merges the individual Bezier paths and curves into a single continuous Bezier path.

Two or more graphics must be selected for this menu selection to apply. All selected graphics must have a defined Bezier Path. This requirement means that text graphics cannot be included in a Join group.

Selecting the Weld menu action places all selected graphics in a new weld group. The top graphic of the group is used to define the style of the new path and defines the beginning of the path. The member paths are automatically ordered and possibly reversed to form a continuous path circuit for the merged path. The path sequence is determined by finding next path termination (start or end) that is closest to the previous path tail end.

The top most path in the painting order determines the color and style for the welded group path. The lead path will determine the circuit direction of the merged path. The subsequent order of paths is determined by closest proximity of any end point (start or finish of a path) to the end of the previous segment.

If adjoining ends are in close proximity, the vertices are merged to a single vertex (the end point of the previous segment. If they are spaced apart an additional straight line segment is inserted to make sure the full path is a closed path.

This method of grouping is useful for combining a group of paths into a single closed graphic. The automatic ordering makes it easy to simply form the group in a fashion that would seem obvious to the observer of the static group of paths.

EazyDraw provides a similar grouping action called Join. This Join action does not make automatic decisions on the ordering of the merged paths. This allows the user to control the merged continuous path using curve direction and painting order.

EazyDraw provides an alternative to these grouping actions for merging paths. This is the Welded Path conversion action found on the Convert Menu on the tools main menu. The welded conversion can be more convenient in some cases, it generates a new Bezier curve from the several curves. Similar to Join or Weld, but the combined single path may be easier to work with than a Group graphic.
