Q - question

DrGrid - parametric grid for AutoCAD drawings.

A - answer If you need to draw a rectangular orthographic or polar underlay (matrix, network, X-Y line raster) in your AutoCAD DWG drawing, you can use the free add-on utility CADstudio DrGrid from

This generator automatically creates a regular Y- and Y-axis line grid or a polar circular grid in a specified area. The default offset equals to the current visual grid step (F7). Optionally you can autonumber the drawn lines. Every N-th line can be emphasized. In the 3D mode, a cube (box) grid is generated.

The generated underlay grid is created in a given layer (can be set as non-printing), in a given color and linetype. The grid layer is locked and drawordered to the back of your drawing. It is cleared before any new grid is drawn.

DrGrid - visual grid as real drawing entities (objects).

Polar grid numbered, sample function from 2DPlot superimposed:

Examples of DrGrid:

You can use LISP variables to predefine grid parameters:

(setq DrGridLayer "DrGrid") ; layer
(setq DrGridColor 8) ; color
(setq DrGridMajColor 9) ; majors color
(setq DrGridTransparency 30) ; transparency
(setq DrGridLineType "DOTTED") ; linetype
(setq DrGrid3D T) ; in 3D?
(setq DrGridPolar T) ; polar grid?
(setq DrGridNumber T) ; numbering?
