Undo undoes the last thing you did. Undo only works on operations that change the model.
Cut will take the selected objects out of the model and put them in the clipboard. Objects maintain their material definitions and other characteristics.
Copy will copy the selected objects from the model and put the copy in the clipboard, the objects will remain in the model and can be pasted again into the same model or a different model.
Paste places copied objects into the model space according to their original world coordinates. If you want the pasted objects in a different location, just move after pasting. To paste into openings, copy a window frame or door (create your own or copy one from the DesignWorkshop 3D Libraries), select an opening, and then paste. A dialog box will open, allowing you to choose scaling and alignment options. Once you click OK, the frame is scaled, rotated, and moved to fit exactly into the selected opening.
Select all will select all of the currently visible objects in the model. If the cursor is in a text field, such as the phases windoid, select all will select all the text.
Duplicate creates a single copy of an object or group. The new object is offset horizontally by two grid-snaps east and south (so that the copy is not confused with the original). At the end of a simple Duplicate, only the new object is selected.
Duplicate Linear allows rapid creation of straight-line arrays of copies. The menu command brings up a dialog box for you to specify offsets from one object to the next, measured independently north/south, east/west, and vertically. The total number of objects to result is specified (including the original in the count). At the end of the operation the whole set of objects is left selected, in case you want to group them, move them, or duplicate again.
To make a two-way rectangular array of objects, such as for a column grid, first Duplicate Linear in one direction, and then while the objects are still selected from that operation, Duplicate Linear in the perpendicular direction.
Duplicate Circular provides for the creation of circular arrays of objects. The menu command brings up a dialog box in which you specify the total number of object, the degrees of rotation from each object to the next, and the vertical offset from each to the next, if any.
After clicking OK, click once in the model space with the 3D crosshair to indicate the position for the axis of rotation. The axis of rotation is always parallel to the "Z" or option-drag direction of the current working orientation. To change the axis of rotation for Duplicate Circular, switch to a different working orientation.
Duplicate Mitered works like duplicate circular, but a copy of the original object is extended sideways to meet its neighbors. This lets you create radial joined elements such as domes and spiral stair-cases, or general "lathed" forms.
The axis of revolution is always parallel to the Z-axis of the current working orientation. The object extensions for mitering are based on a cross-section of the original object cut by one of the major orthogonal planes of the current working orientation.
The Scale menu command is used to numerically change the size of objects and groups. The scaling percentage for each of the horizontal scales and the vertical scale of an object can be set independently. Each object scales about its center, so, to scale several objects and the distances between them, or to scale an entire model, first group the objects.
The Wallify function turns solid massing models into space-filled walled models. Select an object, and choose Wallify from the Edit menu. This brings up a dialog box to set a Wall Thickness (which has a default setting of 0.5 ft.), and then replaces any selected blocks with four walls mitered together at the outside corners. These walls are now separately editable. Blocks and extrusions can be wallified, even when they have tilted ends.
When you Cut or Copy objects, the clipboard automatically receives the objects in both 2D and 3D form. Thus, you can directly copy and paste 2D PICT graphics into most Macintosh drawing, paint, or word processing applications. To preview the 2D view before switching to another application, use the Show Clipboard command.
