The importing of marker information is possible from DXF as well as GHS and Seaway section data files.

The Import DXF Markers command from the File menu can be used to import lines, arcs or polylines from a DXF file and display them as markers in the graphics views in Maxsurf. Each point at the end of a line or along a polyline will be converted into a marker.

To import a DXF file as markers:

·   Choose Import->Import DXF Markers from the File menu

·   Set the XYZ orientation of the data in the file

You can use the radio buttons in the middle of the dialog to specify the orientation of the points in the file relative to the Maxsurf coordinate system. For example, choosing +ve (positive) and X in the Forward section means that +ve X coordinates in the DXF file will be aligned with the forward direction of the Maxsurf model.

Also see: Maxsurf Coordinate System on page 36

The coordinates in the file are positioned relative to the current Maxsurf zero point.

·   Set the units of the data in the file

Click on the radio button corresponding to the units of the data in the file.

·   Optionally set the arc segment length

If you are importing arcs from the file, these will be converted into line segments before importing. This field can be used to specify the length of the line segments along the arc.

·   Optionally save the configuration

You can use the Add button at the bottom left of the dialog to add a configuration and save the setting for future usage. For example, if you frequently import from AutoCAD, you might like to set up a configuration, named AutoCAD, to save your import settings.

·   Click OK to import the data

Once imported the markers can be manipulated in the usual way, including assigning to a particular station or associating with a surface. See also Markers section.
