Table 1. Edit menu items in the Model mode
Menu item Description Same effect as selecting…
Undo Negates the last drawing operation. You can undo a series of modifications by repeatedly selecting Undo. CTRL+Z
Redo Negates the last undo modification. You can redo a series of negated modifications by repeatedly selecting Redo. CTRL+Y
Cancel Cancels the current drawing operation. Esc
Overall Dimensions … Opens the Overall Dimensions dialog, which is used to specify the size of the workspace that will be required to create the section. The minimum it should be set to is the overall dimensions of the section but can be set larger.

Locate circular external contour Opens the Radius of the external contour dialog, which is used to specify a radius value for a parametrically defined, circular external contour.
Note: This menu item is only active if no other external contour has been defined.
 
Draw internal contour Used to set or clear the internal contour mode, which is used for creating internal openings within an external boundary.  
Copy inner contour > <list> Used to window either a rectangle or polygonal area to select one or more internal contours for copying. Copies can be placed manually or by specifying offset distances.  
Multiple copy of inner contour > <list> Used to window either a rectangle or polygon area to select one or more internal contours making multiple copying. Copies can be placed manually or by specifying offset distances and a number of copies.  
Delete internal contour Used to set or clear the delete internal contour drawing mode, which is used to remove internal contours by clicking anywhere in their boundary.  
Insert circular hole, center, and radius Used to set or clear the circular hole drawing mode, which is used to define the center of a hole (e.g., a parametrically defined, circular inner contour) and radius graphically.  
Insert circular hole with defined radius Used to set or clear the circular hole with defined radius drawing mode, which is used to define the center of a hole graphically and then specify an exact radius.  
Parametric hole … Opens the Parametric holes dialog, which is used to define the location and dimensions of either a circular or rectangular inner contour.  
Radius corner … Used to set or clear the smooth corner drawing mode, which is used to select a corner to fillet and then opens the Smooth radius dialog to specify a radius value for the rounded corner.  
Move vertices Used to window either a rectangular or polygonal area to select one or more vertices to move. Vertices can be moved either manually or by specifying offset distances.  
Edit vertices Displays all vertex numbers in the View window and opens the Coordinates dialog which is used to specify precise coordinates of each vertex for a selected contour.  
Delete vertices Used to select a single vertex or window either a rectangular or polygonal area to select one or more vertices for deletion.  
Coordinate center … Opens the Coordinate Center dialog, which is used to specify shift the global coordinates to either an arbitrary location or to the center of gravity of the shape.  
Table 2. Additional edit menu items in the Triangulation mode
Menu item Description
Create density points for contours

Used to add triangulation points on external or internal contour lines. As with the vertices for the contours, nodes for the triangulation will always be generated on these points. Density Points are displayed with a red dot.

Note: If a vertex at either end of the line is moved, then the density point will be moved in such a way so that the point will remain in the same proportion along the line defined by the new vertices
Mark nodes as density points Used to modify the density around a selected vertex.

Once selected, a method of vertex selection must be activated from the status bar.

Delete density points Used to remove any density settings on nodes and remove density points on lines or inside entirely.
Create density points inside

Used to define density points inside the external contour. Density Points are displayed with a red dot.

Note: If the Snap to Grid option is active, then the density point will be added to the nearest grid intersection.
Create density regions Used to define areas within the external contour of higher density.
Delete density regions Removes any Density Regions that have been created.
Border density lines Used to specify the density setting along an external or internal contour.
Note: Border Density Lines cannot be applied to lines that have had Density Points on Lines applied or already have had a Border Density setting applied. These should be removed and the new Border Density setting applied.
Internal density lines Used to specify density lines within the envelope defined by the external contour. Density lines are displayed in green.
Crack lines Used to add crack lines to the surface model.
Delete density lines or crack lines Used to delete a selected density line or crack line.
Create triangulation points on the lines Used to add triangulation points along the external or polygonal internal contour lines. The Advanced Mesher will be forced to create mesh nodal points in these locations. Triangulation points are displayed with a blue dot.
Delete triangulation nodes Removes any density settings on nodes and removes density points on lines or inside entirely.

Once selected, a method of node selection must be activated from the status bar.

Table Opens the coordinate and density table, which displays data for each of the points that have been defined in the surface model. Both the coordinates and density values can be modified.
Note: Additional density and triangulation point coordinates must be modified in such a way as they still remain upon a straight line between the vertices that define the line.
Density parameters (lines, regions) Sets or clears the density parameter modification mode. When set, selecting a density line or region opens the density dialog for that line or region allowing you to edit the density value.
Triangulation Opens the Triangulation dialog, which is used to specify the meshing method and associated parameters for meshing.
Change triangulation density … Used to select a region in which the mesh density is locally revised after the mesh has been created by defining a density region using either a rectangular or polygonal region.
Smoothing … Opens the Smoothing dialog, which is used to improve the mesh quality to be improved by selecting a criteria and number of times that criteria is repeated.
Display mesh quality … Opens the Mesh Quality dialog, which is used to visualize an aspect of the mesh by color coding to evaluate the mesh quality.
Mesh quality table … Opens the Quality Table, which displays the range of values for a number of parameters for a triangular mesh.
