gvSIG-Desktop 1.12. User manual
This section deals with gvSIG’s drawing commands. The rest of the commands can modify the elements but with the exception of the “copy” command, they cannot create new features and we thus require the actual drawing commands to do so.
gvSIG includes basic drawing elements, such as lines, circles or polygons, which can be used to obtain any complex drawings.
All the elements you wish to insert need one or several points to be specified so that they are correctly placed in the drawing.
Remember that the tools to insert new elements vary according to the type of layer being edited. Thus, for example, a point can only be inserted in a point-type layer and is not supported by any other type of layer.
