Using the Grid
When working in the product, you have the option of turning on the grid in any view. The grid consists of evenly-spaced points in the design plane. It is a visual measurement and alignment aid.
Defined spacing between grid points and between grid references (highlighted grid points — every 12th point, for example) are collectively known as grid units. Grid unit settings are specific to each model in a DGN file. The appropriateness of grid unit settings for a design task is related to the size of the design, working units, and the required precision.
When used in conjunction with Grid Lock, the grid can assist in accurate "by eye" placement of elements. However, the grid can be an impediment to efficiently using AccuDraw.
