Usually, CC3’s grid is aligned horizontally and vertically. CD2 adds the option to angle the grid to make it easy to draw buildings parallel to roads when snap is on.
Only pre-defined angular grids may be aligned. All CD2 maps include angular grids. You can add angular grids to any map.
To angle the grid.
1 The prompt reads "Angle or select entity:" Select a point. If the point is on an entity, CD2 will snap to it. Alternatively, you type an angle you want to align the grid to and the command finishes.
The prompt reads "bearing to".
2 Select a second point. If the point is on an entity, CD2 will snap to it.
The grid is now aligned. If you try to align a non-angular grid, a message box says
"The currently selected grid is not an angular grid"
