Defining Blocks with Attributes
You have to define two blocks for the grid symbols and their attributes. The
insertion point for the block used for the top of the grid should be at the lowest
point of the circle. The insertion point for the block used for the left side should
be at the point on the circle farthest to the right. Follow these steps:
1. Click the Create button on the Block panel to start the BLOCK com-
mand, and open the Block Definition dialog box.
2. In the Name drop-down list, enter GRID-V (for vertical) and then
click the Pick Point button in the Base Point area.
3. In the drawing, use the Endpoint osnap and select the gridline that
ends at the circle on top.
4. In the Block Definition dialog box that reopens, click the Select
Objects button in the Objects area.
5. In the drawing, select the circle and attribute definition on the top.
Press ↵ .
6. The Block Definition dialog box reopens once again, click the
Annotative check box in the Behavior area.
7. Be sure the Delete button is selected in the Objects area. Verify that
the Block Definition dialog box looks like Figure 9.7, and click OK.
