Work with grids
A grid represents a three-dimensional complex of horizontal and vertical planes. The grid is shown on the view plane using dash-and-dot lines. You can create both rectangular and radial grids. Use grids as an aid in locating objects in a model. You can make rectangular grids and grid lines act magnetically so that the objects on the grid lines of a rectangular grid follow if you move the grid line.
Grid terminology
(1) Grid origin is the point where the zero points of each coordinate axis intersect
(2) Grid line extensions define how far the grid lines extend in each direction
(3) Grid labels are the names of the grid lines shown in views
Several grids in one model
You can have more than one grid in a model. You can create a large-scale grid for the entire structure, and smaller grids for some detailed sections. Create as many grids as needed, so that you can easily place objects in your model.
Single grid lines
You can create single grid lines and attach them to an existing grid.
Single grid lines have handles. If the Select grid line selection switch is active and you select a grid line, the handles appear in magenta. If you move the handles to make a skewed grid, you can do this only on the local XY plane of the grid.
