Write DXF Job

This option writes points, strings and text to the nominated DXF file. The dialog box allows the user to choose which ACS objects (points/strings/text) are to be written to the DXF file.

Output File
Enter the output filename, the default extension will be .DXF.

Browse the disk to select the directory for the output file and the output filename. If you select an existing file, you will be warned and allowed to append the data to the existing file or you can overwrite the existing file.

Select Points/Layers
You can select individual layers and ranges of points to be written to the file, enter the starting and ending point numbers of the range of points required. See Select Points/Layers for more details.

If multiple options are used only those points which fulfil all the checks will be written to the output file.

Layer Code Translation
This option allows layer names and codes to be converted to different (Customer specified) layer names and codes when writing an output DXF file. See Layer Translation for more details.

The ACS objects are all output according to their current display parameters. Attributes such as layer, colour, line type (style), rotation angle and font size are converted to their corresponding DXF equivalents. If the user has chosen a layer/code translation file, it is used in the conversion of points to their DXF equivalent.

If you choose not to use the layer/code translation file, be very careful with layer names. AutoCAD is not as flexible with its layer naming conventions as ASCP. AutoCAD does not appear to allow punctuation or spaces in its layer names. If you get errors when importing the DXF into AutoCAD, it may be because a layer name does not meet AutoCAD’s layer naming convention.

Include Heights
Tick this box to output the Z co-ordinate (if available) of each point.

The DXF header allows for the DXF file to be customised. This DXF conversion sets:

Points as Symbols
If you tick this box all point symbols are written to the DXF file as DXF ‘INSERT’ commands. The point symbols are predefined in the BLOCK section of the DXF header. At each point co-ordinate, the point symbol is INSERTed with the appropriate layer, colour and rotation. The point number, RL and point code are also output as TEXT if they are to be displayed in the DXF job.

If the following box is ticked (Output Symbol Definitions) the symbols are written to the DXF file as blocks and will be used to display the points. If the following box is not ticked (Output Symbol Definitions) the symbols are not written to the DXF file as blocks and Autocad will use any current definition it has for the symbols, if any.

Note: The point symbol colour may not appear as you expect. The point symbol block is always drawn in the colour of the layer on which the point symbol has been drawn, not in the colour specified in the INSERT command.

If this box is not ticked, points are written to the DXF file as POINT entities. They will appear on the screen in Autocad as single pixel dots. This is because there is no symbol attached to the point to be drawn and make them easy to see. You can select the POINTs and assign them a symbol.

Output Symbol Definitions
Tick this box to write the symbols to the DXF file as BLOCKS, each point symbol then refers to one of these BLOCKS. If the box is unticked, the symbols YOU MUST SUPPLY THE BLOCK DEFINITIONS, these would be defined in the Autocad drawing before reading in the DXF file.

Line Styles as CONTINUOUS
Tick this box to override the ACS line style and force the output line style to be a solid CONTINUOUS line. If this box is not ticked, the ACS line styles are translated to equivalent DXF line styles.

Release 13 DXF File
Tick this box to write a Release 13 (or above) compatible DXF file. Autocad changed the DXF file format radically at Release 13. This new DXF file format does allow for complex line types e.g. Electricity lines etc.

Truncate Lines to Circle Symbols
Tick to truncate lines which approach a circle symbol (symbol=1). This can be used for ‘peg’ points in a subdivision.

Null Z Value
Point with no height value in the GeoSurvey job will be given this height value in the DXF file. If this field is left blank and a point has no height, no height value will be output to the DXF file. Points
Points are output as XY(Z) points in space and appear on the AutoCAD screen as a dot in space. This type of file is suitable if the points are to be processed further by other programs, the other programs are only interested in the X,Y,Z values of the point.

All strings are output as a series of DXF LINE commands. This allows us to change the colour and linetype for each line segment of the string. The lines are not drawn with a width. If the string is a lot, the lot number and/or area may be written to the DXF file. The View->Display Setting dialog box controls whether or not the lot numbers/areas are displayed.

All text is output as DXF TEXT commands.

The DXF file output by the conversion should be importable (without change) into AutoCAD R14.

There is an option the GeoSurvey_config.xml file to control whether Fontsare exported to the DXF file.
This option is the <dxfFonts> option.

When you enable this option (set to Yes), it will only export ceryain fonts. Due to the complexity of the dxf file format only the following fonts are supported at present.
Alial, Calibri,Cambria,Courier New, Lucida Sans, Tahoma and Time New Roman.
Let me know if you absolutely need a different font.

Also, for Text items, the Bold and Italic attributes will not transfer to the DXf file.
If you absolutely need these, let me know.
