DXF

Here the parameters for writing a graphic file in the DXF file format can be set. The elements, according to the set display parameters, are written in the DXF file. The elements stored in the turned off levels (i.e. the elements not displayed in the active window) won't be stored in the DXF file.

Header:

Use this button to store the header in the DXF file. In the header are stored the information on the levels required for some programs (for example, if MicroStation doesn’t find the header, it will store all the elements to level 1).

Exchange the coordinates X and Y

Turning this option on, GROMA will, during the export, exchange the coordinates X and Y (for some systems, this is necessary for the correct placement of the coordinate axes).

3D:

This button allows the export of points in three dimensions for processing in a three dimensional graphic system. If this option is switched off, the height is exported as a text description.

Reduce:

If you turn this option on, the coordinates will be, during the export, reduced by the reductions set in Settings->Reduction.

Coefficient X/Y/Z:

Here you can set the coefficients with which the pertinent coordinates of the output are multiplied. In case of the mathematic coordinate system used by the majority of CAD systems, the coefficients for X and Y must be set to the value -1 for the correct position of the coordinate axes.

Text height:

Set here the required text height. Enter the height of the real size in meters (e.g. to display characters 2 mm tall in scale 1:1000 you have to enter 2m).

Font for point numbers / heights:

Shall the DXF file contain the font name for the text elements, you can enter it here. If you leave these input lines empty, the item with the font name won't be contained in the DXF file.
