are a set of tools to edit existing shapes in a comfortable way. Move Point, Move Edge and Insert Polygon Point are an interactive editing mode. Scale, Size Adjust, Snap Shapes and Round Elements will modify selected shapes.
Interactive mode to move a single point of a shape. Once a point is choosen, you can move that point graphical or (with a shift left mouse click) enter its coordinates in a dialog.
Similar to the move point mode, but a edge (=two neighbored points) are moved.
An additional vertex is added to a polygon or path in a graphical way.
Selected elements are scaled. First the origin point has to be entered. That is the point which will not moved anyway. In a second step the scale factor can be entered graphical or nummerical way. To do a graphcal entry you need to press the shift key when entering the origin point. Then you can enter a second point (source point) and third point (target point). The design is scaled in a way that the source point will be scaled to the target point.
Use this function to increase/decrease the size of all selected shapes. A dialog will be opened to enter a value in user units. All edges of selected shapes will be move by that value. A negative value will shrink the shapes. A asymmetric size with a different values in x- and y- directions is also possible. There are four different ways to handle the corners.
Selected shapes/points will snap to near elements within a defined search radius. A dialog will ask for the radius.
Use this function to move all selected points on a grid. You will be prompted for the grid-size.
