How to change the display order of the prompts that are displayed when you insert a block with attributes.
The order of the attribute prompts is the same as the order in which you selected the attributes when you created the block. However, if you used crossing or window selection to select the attributes, the order of the prompts is the reverse of the order in which you created attributes. You can use the Block Attribute Manager to change the order in which you are prompted for attribute information when you insert the block reference.
For the selected block, attributes are listed in their prompt order.
