You can edit a master block from the Library window by right-clicking the block and then selecting the Open command from its shortcut menu. All elements that comprise the master block are displayed in a new edit window. Labels included in the block are displayed using the label name rather than the label value.
You can add, edit, and delete master block graphics, you can add and edit label name-value pairs, add annotations that reference block property text, and add dimensions.
You can move, rotate, scale, mirror, and stretch any of the block elements.
When you exit the edit session by clicking the Return button on the command bar, the changes are applied to the master block. If there are occurrences of the master block in the active document, they are updated, too.
You can select multiple blocks to edit the color, line style, line width, and block scale. If the selected blocks have the same line color, line type, line width, or block scale, the values for these properties are displayed. If they are different, the line color displays a blank color, the line type displays no selection, the line width and block scale contain no value.
When you single-click a block occurrence:
Edit handles are displayed. There is one handle for the block graphics and one handle for each label that can be modified in the block. If a label has been defined so that its position is locked, then no edit handle is displayed.
You can use the Block Occurrence Selection options on the command bar to change the block name, block scale, block properties, and 2D element line style and color.
When you double-click a block occurrence:
It is the same as selecting the Open command to open the block for editing in a Draw In View window.
You can use any of the standard drawing commands to edit the block.
You can edit a label that is part of a block using the Open command on the block shortcut menu. If you select the Open command from the Library tab, then your edits update the master block. If you select the Open command from the drawing, then your edits update the block occurrence. When you click Return, all changes are saved to the block and label definition.
Editing block labels produces these results:
If you edit a label definition in the master block, and if label formatting and location properties have been changed locally in individual block occurrences, the occurrence settings are preserved.
Changing an existing label so that it is set to Use Same Value in All Occurrences changes the value of all occurrences to the value defined in the master block.
Deleting a label in the master block deletes it from all occurrences.
Adding a new label adds it to all occurrences. The default label location and value is taken from the master block.
Changing an existing label so that the Lock Position Within Block option is set changes all the occurrence labels to the location specified in the master block.
Moving a label that has the Lock Position Within Block option set moves all the labels in all occurrences relative to the master block origin point.
Blocks and views created from blocks can be renamed only from the shortcut menu in the Library. Block names and view names must be unique within the active document.
Select the block name, select the Rename command from the shortcut menu, then type the new block name over the existing block name, then press the Enter key.
Blocks can be deleted only from the shortcut menu in the Library. When you delete a block in the Block Selection Pane, all occurrences of the block in the active document, including all views of the block, are deleted with it.
You can cut and paste blocks and copy and paste blocks between documents using those commands from the selected block's shortcut menu. When pasted in the new document, a new occurrence and/or master block, are created.
A block and all its occurrences can be replaced globally with a single command, or you can choose to replace only a selected instance of the block. The replacement replaces the block graphics as well as its attributes.
The Replace command is available only from a block's shortcut menu. When you replace from the Block Selection Pane in the Library, all occurrences of the selected block in the active document are replaced. When you replace a selected block in the drawing, you can choose whether to replace that one or all instances of the block.
The Unblock command operates on graphics in the 2D Model sheet or active drawing sheet, dropping the selected block occurrence to its individual components or elements. If the selected block is nested, only the top level block will be unblocked.
If you want to select an existing block's graphics as the basis for a new master block or another view of an existing block and the block occurrence is not selectable, use the Unblock command on the block's shortcut menu in the drawing before selecting the Block command or the Add Block View command.
If you dragged a file into the drawing and the contents of the file translated as a single block, you can separate the contents into individual elements using the Unblock command. This makes them selectable when you create a new block or add a block view.
You can copy and paste block occurrences between sheets and between documents. When a block occurrence is pasted into a document, the settings on the master block determine the values of the labels of the new occurrences.
