Export of 3D DXF

This function can export data in a DXF file with faceted objects. The program creates two different types of DXF entities, namely 3DFACE or POLYLINE mesh. The box and general cylinder primitive are generated with 3DFACE and spherical segment, cone, torus and rotational primitive are generated as POLYLINE mesh.

Note: This function will only export hull models; all outfitting models will be ignored. For outfitting models you need to use Explant-A or Mechanical Equipment Interface from Draft Design. (Please note that these functions require separate licenses in addition to an Draft Design license.)

BLOCKS at two levels are used to create a hierarchical data structure. Block names are equal to the model names. Some attribute info are also transferred for the blocks; Object type, Posno, Assembly name. Also different layers are used for different types of objects.

The DXF files become very big even for a moderate drawing size and it is a good idea to limit the size. The level of detail determines how the faceting of primitives are made (all data in DXF are plane sides). A level of detail equal to 2 is appropriate when many models should be transferred. A factor which also is very essential for the drawing size is which input model representation was used when the drawing was created. A panel with cutouts generates a DXF file which is three times as big as without cutouts. Also it is possible to choose if the stiffeners or brackets should be drawn with or without endcuts, which are also "expensive". Panel representation parts should be used, since then holes which are outside the outer contour is intersected into the outer contour.
