Abstract

In an electronic-mail computing system having a display and a pointing device for entering geometric elements in a geometric document, additional writing space is inserted in an existing geometric document having original space with one or more original geometric elements. This is accomplished by creating a boundary line or split line and inserting open or free space at the boundary line in the document. Further, an insertion of a boundary line in the midst of a geometric elements of a document to split the elements and add free space is accomplished by grouping geometric elements split by the boundary line or split line and then locating grouped geometric elements on one side or the other of the split line before space is inserted at the split line. The split line on the geometric document is detected, and original geometric elements crossed by the split line are detected and identified as crossed geometric elements. Any original geometric elements connected to or related to the crossed geometric elements are grouped to collect them into one or more geometric element groups. Each of the geometric element groups is analyzed to determine which side of the split line each group should be located. Then a duplicate split line is dragged using the pointing device from an original split line position to a new position while leaving the original split line at the original split line position. Open space is inserted between the split line and the duplicate split line.
