Undo

Cancels the last action.

Redo

Cancels the last Undo.

Unselect All

Unselects all points, lines and blocks, see Canceling selection.

Select All

Selects all points and lines, see Selecting all elements.

Delete

Deletes the selected points and lines, see Deleting elements.

Merge Points

Merges selected points being closer to one another than the tolerance. You need this option e.g. to connect two line ends.

For information about using the tolerance, see Using Tolerance and Raster.

Split Lines

Moves selected points to the closest selected line by normal projection, if the point is closer to the line than the tolerance. The result is split lines.

For information about using the tolerance, see Using Tolerance and Raster.

Intersect Lines

Generates points at all crosses of the selected lines. You can select many lines at once.

For information about using the tolerance, see Intersecting lines.

mesh Alignment

Moves all selected points to the closest raster point, even if the raster is off, see Using mesh alignment.

Copy/Move To

Dialog for copying or moving selected elements, see

Copy/Move to

Create Block

Groups all selected lines to a block. Each line can belong to one single block at a time. Each block has an associated color, see Working with blocks.

Rotate Selection

Rotates all selected elements, see Rotate selection dialog.

Flip

Turns over the geometry. To get the primary state select the option again, see Applying Flip.

Mirror

Swaps the geometry left/right (changes x to -x), see Applying Mirror.

scale

Multiplies the coordinates of all points with the scale factor, see Scale dialog.

Align Left

Moves the whole drawing so that the point with the smallest x coordinate is on the symmetry axis. This is useful e.g. for imported *.dxf files, see Importing a CAD File (dxf-Format).

Align Origin

Moves the whole drawing so that the point with the smallest x and y coordinate is on the origin (x = y = 0). This is useful e.g. for imported *.dxf files, see Importing a CAD File (dxf-Format).
