Grid bubble objects are dimensioned grid lines with bubble markers. This type of drawing notation can help locate columns and other primary building features on construction documents.
To draw a grid bubble object:
1. Click the Grid Bubble tool from the Dims/Notes tool set.
Place a line of grid bubbles by drawing an open polygon with the tool. The first click starts the grid line; the second click determines the angle of the grid line and sets a marker at that location. Each remaining click sets a grid marker. Grid marker objects maintain a constant size regardless of the drawing scale.
2. Double-click to end the grid line. The first time the object is inserted in this session, the Preferences dialog box opens. These parameters apply to subsequent placements of the object and can be changed in the Object Info palette.
The grid bubble parameters can be edited in the Object Info palette.
Click to show/hide the parameters.
By combining several bubble grids and adjusting labeling properties, hierarchical (nested) grids can be created.
