Transform - Split With

Split target areas and lines using a given set of lines. The transform takes the given set of lines and cuts into separate objects any line and area objects that are intersected by the lines.

 

Example

Suppose we have a drawing with an area and a line.

We select the line and in the Selections pane save this selection as a saved selection called line.

We next select the area and in the Selections pane save this selection as a saved selection called area.

We can now set up the transform toolbar with the Split with operator as seen above and press Apply

The result is that the area object is split into two areas, neatly cut by the line. We can select the rightmost area.

If we press Delete the area disappears, proof that what was once one area was split into two areas.

 

Comments

 

The Split with operator uses any set of lines to split any combination of areas or lines. The example above shows just one line being used to split a single area. We can use the transform in far more significant ways. For example, we could use lines showing streets to split a background area and thus create areas within the various streets that could be used as city blocks, or we could use the boundary of Switzerland to "cookie cutter" VMAP 1 lines and areas that cross the border.
