A CAD raster is a visible grid or background image used in computer-aided design (CAD) software. It forms a series of equidistant, intersecting lines in both horizontal and vertical directions, similar to squares on paper.
The role of CAD grid has the following points:
Assisted Alignment: CAD raster provides a reference grid that helps users more accurately align and position objects during the drawing process. By aligning to grid lines, balance and consistency of design elements can be maintained.
Scale and dimension: Grid lines can be used to measure and determine the spacing, length, and scale between objects. This helps ensure that the design meets the desired size requirements and maintains the accuracy of the design.
Layout and arrangement: CAD grids can be used to plan and lay out design elements. By aligning objects with the grid, you can create a symmetrical, even, and neat layout, making the design look more professional and easy to understand.
Reference drawings: raster images or base drawings can be used as background references and drawn in CAD software. This makes the drawing process much easier, especially in complex design environments where design elements can be placed exactly where they are specified.
Visualization Assistant: In CAD software, grid lines can be used as visualization AIDS to help users better understand and analyze designs. With gridlines, the relative positions and spacing between objects can be observed and adjusted to achieve better design results.
Overall, CAD grids play a role in assisting positioning, layout, and measurement during the design process, providing a convenient way to create accurate, consistent, and professional designs.
