BlockEdit | Rhino 3-D modeling

The BlockEdit command allows selecting a block instance to change the block geometry and update the block definition.

Steps

Select a block instance to edit.

Or, double-click a block instance.

The block geometry opens in the Rhino window. All other objects are locked.

You can now edit the geometry in the block using any editing techniques.

Block Edit command-line options

PromptToEditLinkedBlocks

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.

Yes

The Yes option prompts to open a linked block.

The No option opens the linked block without prompting.

Note: 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.

Add Object

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.

Note: The object added is copied to the block definition and the original object remains in the model.

Remove Object

Removes selected objects from the block definition.

Note: When the block is updated, the removed objects are added to the model as separate individual objects.

Set Base Point

Repositions the block insertion point.

Note: When the block is updated, the block instance will shift so the new insertion point is placed at the block insertion location.

When all changes are complete, click OK.
