Adding an Attribute

An Attribute is a piece of information that can be attached to the Block. An attribute can be the code for a specific door or window or it could be the current rating for a fuse. You do not have to add an Attribute to a block. If you do not wish to add the Attribute then move to the next step.

You are prompted.

Add an Attribute name, Prompt text and Default value and set the Text display.

Click OK and you will be prompted.

Position the Attribute and click to insert it.

Creating the Block

We first need to select everything that we would like grouped to make the block. Use a selection box or press Ctrl + A.

Select Tools > Create Block and the Make Block dialog box will be displayed.

Name the Block and give it a description if necessary.

Click OK and you will be prompted.

Select an appropriate base point (Hook/Insertion point)I for the block and press Enter or click.
