Varkon Interactive users manual
The DXF was originally defined as a DrawingeXchangeFormat for AutoCAD but is now widley used to exchange 2D geometry between systems of various kinds. DXF also has support for simple 3D geometry. Varkon supports import of DXF files through a module library, see VARKON_ROOT/sources/Vlib/dxf. Import is limited to support only the most common entities and attributes of the DXF specification.
Varkon DXF export supports all Varkon entities. Varkon entities that are not supported by the DXF specification are converted to the DXF POLYLINE entity.
The ANSI IGES is supported by most CAD systems, primarily for import and export of 3D wireframe and surface geometry. Varkon supports import of IGES files through a module library. See the README_IGES in VARKON_ROOT/sources/Vlib/iges for more info on the IGES import library.
Varkon does not support IGES export.
STL was originally defined as a file for rapid prototyping using STereoLitografy. It is a simple 3D limited to plane triangular facets. Varkon supports import of STL files in text or binary . Each facet in the STL file is mapped to a b_plane in Varkon.
Varkon supports export of b_planes, facet surfaces and mesh entities on STL text .
The PLT is used by Varkon primarily for printing and plotting but can also be used for static 2D symbols. The PLT conforms to the ISO GKS Metafile specification for 2D vector graphics. Varkon supports export of all entities on PLT .
Varkon supports import of PLT files through the MBS SYMB() procedure.
