Edit Blocks > Create Block Definition |
Ctrl (CMD) + B |
The Block command defines a block object from the selected objects and replaces the selected objects with an instance of the block.
Select the objects.
Pick a base point for the block.
This is the point around which the instance will be located, scaled, and rotated when it is inserted.
A block control point is placed at the base point of the block.
Type a name for the block definition.
The block definition is created with the active unit system (model/layout).
Block Definition Properties
The name of the block definition.
See: Naming conventions in Rhino
Optional descriptive information.
Adds hyperlink information to a block definition. This information can be retrieved with the Hyperlink command.
A description of the URL.
A web address. Click the address to open the page in the default browser.
The properties of the geometry (curves, surfaces, etc.) that are contained in the block instance are controlled either by the layer properties or object properties of the geometry itself. Block instances that you insert to the model insert onto the current layer and can be moved to any other layer. There is no relationship between the block instance's layer and the geometry contained in the block. For example, the block geometry does not change to match the layer color onto which the block instance is inserted.
When the block contains objects on a specific layer, turning that layer off will turn off only the objects on that layer. However, if the layer the block instance is inserted on is turned off, all of the objects will disappear.
When you lock a layer, only the layer that contains the insertion point of the block instance is locked. If a block has objects that are on the locked layer, but the block instance insertion point is not on that layer, the object itself is not locked because the controlling factor is the layer of the block insertion point.
Grouped objects will not maintain their grouped status inside a block.
This option is only useful for objects in blocks. Think of a block instance as a container that contains objects (block members). A block instance is the parent of its block members. A block instance has its own properties. If By Parent is selected in the properties of a block member, the properties will be controlled by the block instance.
In this example, Block A contains a cylinder and a box. The Display Color of the box is By Parent and is controlled by its parent (Block A). The box will display Block A's layer color because the display color of Block A is By Layer. The cylinder will always display its own layer color and will not be changed by Block A.
Now Block A is nested in Block B. The box still displays Block A's layer color because By Parent only works with the direct parent.
If the Display Color of Block A is changed to By Parent, the display color of the box will be indirectly controlled by its grandparent (Block B).
By Parent can be selected for Display Color, Linetype, Print Color and Print Width in object properties. For the Render material, select Use Object Parent. Render materials are only visible in Rendered and Raytraced display modes by default.

List structure
The block definition name.
The instance number of the block definition.
The instance number of the block definition nested in other block instances.
The instance number of the block definition regardless of Top Level and Nested.

Block A, B, C, and D are block definitions.
Selecting a block definition highlights its block instances in pink with axes icons.
The pink highlight is cleared when the Block Definition panel loses focus.
Selecting a block instance highlights its block definition in light-blue.
The icons indicate the definition types:
Selects instances of the selected block definition in viewports.
Inserts the block definition to viewports as block instances.
Or, you can drag and drop a block definition into a viewport.
Edits the block definition name.
Deletes the selected block definition and all of its instances in the model.
Block definitions nested in another block definition cannot be deleted.
Makes a new copy of the selected block definitions.
Reloads the external file to see the latest changes.
The icon appears behind the block definition name when the linked block is out of date.
Lists the details of the selected block definition in the Block Instance Info dialog box.
Saves the block definition's component objects to one of the file formats supported by Rhino.
Block A has 5 top-level instances and 2 nested instances in the model.
Block A contains a curve (a1) and a surface (a2).
Selecting an object of a block definition highlights the objects in viewports.
The icons indicate the object types.
Block object context menu
Selects the object in viewports.
Edits the name of the block object.
Deletes the block object from the block definition.
Block A and B are nested in Block D.
The icon indicates they are nested blocks.
The status bar shows how many block definitions in the model and how many of them are currently selected.
Point the mouse cursor to the status bar to show a tooltip for the count of different block definition types: Embedded, Embedded and linked, and Linked.

Units
(Embedded block definitions only)
The units of the block definition.
If you change the Block units, you will be prompted if you want to scale the block definition.
Definition Type
Saves geometry in the model. The block definitions will not update when the external file changes.
Saves geometry in the model and maintains a link to the external file. Linked geometry will update when the external file changes. If the external file cannot be located, the geometry saved in the model is still available.
Only maintains a link to the external file. Linked geometry will update when the external file changes. If the external file cannot be located, the geometry will be missing in the model.
Linked block definitions use both absolute and relative paths.
The missing block location is marked with a text dot object listing the missing block name.
For a description of the process Rhino uses to locate files used by worksessions and linked instance definitions, see Rhino Wiki: File finding.

Linked blocks are not stored in the Rhino file, but are a connection to an external model. To edit linked blocks, Rhino opens the external model in a separate instance of Rhino. The current editing session is paused until the external file is locked. YesPrompts to open a linked block. NoOpens the linked block without prompting. In the Edit Linked Block dialog box, checking the Don't ask this question again... box automatically sets the PromptToEditLinkedBlocks to No. |
Block Edit options
The Block Edit dialog box displays the block name and a list of any blocks nested in it.
Adds selected objects to the block definition. If the selected object is a block, this becomes a nested block and will display in the tree the next time the BlockEdit command is run.
The object added is copied to the block definition and the original object remains in the model.
Removes selected objects from the block definition.
When the block is updated, the removed objects are added to the model as separate individual objects.
Repositions the block insertion point.
When the block is updated, the block instance will shift so the new insertion point is placed at the block insertion location.
