Description Gerry 2018-03-18 19:19:09 UTC
Connectors are frequently used when drawing diagrams or flow charts. From a graphics design perspective, it should be possible that connectors/arrows in diagrams and flow charts do not directly contact the boxes, but rather to have a gap between the box and connector/arrow. Such a feature does not exist in Draw, but, for example, in the diagram editors Dia and Pencil. In both diagram editors it is possible to either set direct contact (default) or to add a gap between the connector/arrow and the box.

The diagram tool Pencil calls the feature: Connector is "slightly detached".
The diagram tool Dia calls the feature: "line gap" (with detailed adjustment possibilities for distances at line start and line end).

Please see attached screenshots of flow charts with the the "line gap" / "slightly detached" function created in Dia and Pencil.

Ok, sounds reasonable -> NEW
Comment 4 Gerhard Weydt 2019-12-01 23:47:51 UTC
Isn't it sufficient to place a gluepoint a little bit outside the object, setting, if necessary, its position absolute with respect to the edge of the object?
