Custom Blocks

A custom block can also be thought of as a pre-filled template for a block. To create a custom block:

1. Add the block to use as the pre-filled template.
2. Fill out the properties to be the basis of the template.
3. Right-click the block to bring up a shortcut menu.
4. From the shortcut menu, select Add as custom tool. Note this option is not available for the IPD blocks. The Custom Tooling dialog box opens.  A sample is shown below.

5. Opposite Create in:, Leave Custom to place the block in the Custom category on the palette. Or click the down arrow and select another palette drawer.
6. If you wish to upload an icon or graphic for the custom block, click Select to open the Custom Icon Library dialog box. Select an icon, and click OK. The selected icon appears in the dialog box.
7. Click OK in the Custom Tooling dialog box. Composer adds the block to the palette in the selected category.

Note: Custom  Entry and Exit icons do not appear on the palette. It still shows the default Entry/Exit icons.

Using a Custom Block

Use the block as you would any others.  Fields defined as relevant in the Block Data Map are automatically populated in the Properties tab based on the state of the original block when you made the tooling.

• Note: When you create a new block, you must add a mapping to define which fields should be template-aware.

1. Within the palette, right-click a custom block and select Customize… from the context menu. This opens the Customize Palette dialog box.
