Grid Definition from DXF

This dialog is used to import a grid from a DXF file. The supported elements in the DXF file are lines, arcs, circles, polylines, and points. Once imported, points, intersections, and midpoints of the lines can be used as snap points. Arcs and circles are approximated as a series of line segments, whose sizes can be specified. The dialog is also used to modify and manage grids in the model. The left panel displays the names of the grids available in the model, while the right panel shows the properties of the selected grid.

Fields and Buttons

• Grid name: A unique name for the grid system. It can be left empty, and the program will generate one automatically.
• DXF path: The path to the DXF file. Once imported, the path is displayed here.
• Import: Opens a dialog to select the path to the DXF file.
• Scale factor: The DXF file can be in any units. This factor defines the scale between the DXF units and the model units. For example, if the DXF file was prepared in millimeters and the model units are meters, this scale factor should be set to 0.001. A factor of 1.0 is used if no scaling is specified.
• Plane: Specifies the plane in which the 2D DXF should be placed.
• Offset: Specifies how much to offset every point in the selected plane, in model units.
• Levels: A list of levels at which this grid should be placed. For example, if the grid is imported in the XY plane, this field specifies the Z-values at which the grid will be placed.
• Discretisation angle: Arcs and circles are approximated as a series of line segments. This angle in degrees controls the size of these line segments.
• Color: The color to use for this grid.
• Show this grid: Determines whether this grid is visible in the model.

Dialog Buttons

• Delete: Removes the selected grid from the model.
• Add: Adds a new grid to the model.
• Modify: Applies changes to the selected grid.
• Close: Closes the dialog.
