🚪 Simple Dynamic Blocks Creation: Resizable Doors/Windows
Dynamic Blocks are intelligent blocks that can be reshaped, resized, resized, resized, or rotated without modifying the original block, significantly reducing the number of blocks you need to store and increasing your flexibility.
1. Working principle of Dynamic Block
Dynamic Blocks work by linking Parameters (parameters - variables that determine changes) to Actions (actions that occur when the parameters change).
| component | duty | Example of use |
| Geometry | 2D drawings of objects (such as the lines of door frames and panels) | Draw the door panels and frames in their original dimensions. |
| Parameter | Specify the position that can be changed. | Use the Linear Parameter to define the door width. |
| Action | Actions that will occur to the Geometry when the Parameter changes. | Use the Stretch Action to specify which part of the drawing will be stretched when you drag the Linear Parameter. |
2. Main steps in creating a Dynamic Block Door/Window (Resizable Door/Window)
Create a basic block:
BLOCKDraw a door or window in a standard size (e.g. 90 cm wide) and convert it to a normal block (use the or commandB).Enter the Block Editor: Right-click on the Block and select Block Editor (or use the command
BEDIT) to enter the Block editing area.Set Parameter (size):
Go to the Block Authoring Palettes (or Ribbon) tab and select Linear Parameter.
Place the Linear Parameter across the width of the door, specifying the start and end points of the distance to be adjusted.
Set Action (Resize):
Select Stretch Action
Bind Action to Parameter: Select the created Linear Parameter.
Set the control point: Click on the grip arrow of the Linear Parameter to adjust the size (e.g., the open/close side of a door).
Selection Set: Select the pieces of the geometry that you want to stretch when resizing.
Test and record:
Use the Test Block command to test the functionality.
Close the Block Editor and select Save the changes to [Block name].
The result: When you place this door block, you will have an arrow (Grip) that you can click and drag to instantly change the width of the door, without having to repeatedly explode the block and edit it.
