The user can easily reverse an action by using the 'Undo' command. Undo will step back one step at a time through the sequence of undoable operations. All commands which change model state can be undone, except for special exceptions which make changes too large to be undone. Model commands which cannot be undone display a warning which must be dismissed by the user. Commands which change only the user interface state cannot be undone. They can be mixed with model commands, but they do not undo or redo as the user steps backwards and forwards through prior actions. Users may view a list of undoable commands in the 'Command History' viewport.

Undo: (Ctrl/Cmd+Z) This option reverses the previous step up to the maximum number specified in the Preferences.

Redo: (Ctrl/Cmd+Shift+Z) This option restores any steps that have been undone.



MODO provides a special memory buffer for temporarily holding data referred to as the clipboard. A clipboard is extremely useful (nay essential) function when moving data around from layer to layer and scene to scene. MODO adheres to the standard 'Cut', 'Copy' and 'Paste' methodologies universal to nearly all Windows and Macintosh applications. Users can use the commands to manipulate text or numerical values when working in data input fields, or with geometry when working in the GL viewports.

Elements in the clipboard cannot be saved directly, and are cleared from memory when MODO quits, and are therefore not persistent across MODO sessions. Text and numerical data is not application specific and can travel in and out of MODO. Any geometric data stored in the clipboard is relevant only to MODO. This is because each data type has its own buffer. Alphanumeric characters are copied to the system clipboard, while geometric data uses a MODO specific clipboard.

The MODO geometry clipboard will only store component geometry data. Other item types such as 'Cameras' and 'Lights' cannot by stored in the clipboard. Whatever is selected and cut/copied will be what is pasted except with edges; when cut/copy/pasting edges the result will be polylines (two point polygons) and not true edges because edges cannot exist without a polygon. These polylines can be selected in both the 'Edges' and 'Polygons' selection modes. When selecting elements in 'Items' mode, cut/copy/paste will work on all component types at once and paste them in the same state as how they were cut/copied. The clipboard support all associated vertex maps and tags as well, so cut/copy/paste will retain selection sets, material/part tags and when pasted into a different scene, related material surfacing will come along for the ride as well.

To use, user need only to make a selection of some type and then invoke the command from the menu bar under "Edit", or by using the associated keyboard shortcut.

Cut: (Ctrl/Cmd+X) This option removes the selected element and stores it in the clipboard.

Copy: (Ctrl/Cmd+C) This option copies the selected element, leaving the original in place and stores it in the clipboard.

Paste: (Ctrl/Cmd+V) This option inserts the contents of the clipboard into the target layer or field.

TIP: When managing large scene files, or files with multiple layers, the 'Import' option may be more easier to transfer multiple layers simultaneously.



The Delete command applies to any type of selected data. For geometric data this is exactly like the cut command removing the data except that it is not moved to the clipboard. Deletion of vertices removes the vertices, but will leave any remaining vertices/polygons (if applicable). If all the vertices of a polygon are deleted, then the polygon itself will be removed. Deletion of polygons also deletes the associated vertices if they are not needed for any other polygons that stays behind. Deleting an edge removes any adjoining polygons leaving a hole. When in Items mode, deleting an item removes the layer, including all geometry contained within from the Item List. When text is selected in an input field, delete will remove the selected section.

Delete: (Delete key) Deletes the selected element from the scene entirely.



Remove is effectively the same function as 'Delete', however the one notable difference is that when working with edges, removing them eliminates the edge itself, but leaves the neighboring polygons in place essentially resulting in a polygon merge, joining the neighboring polygons.

Remove: (Backspace key) Removes the selected element from the scene.
