Synopsis

PDX_MSGT dgdx_GetGDXData(long option, MDA_PTR dxf_db_ptr, GDX_MATRIX gdx_mtx, int gdx_model, MDA_PTR *gdx_db_ptr)

Purpose

Create the GDX data (in specified model) corresponding to a DXF entity.

Description

Gets the GDX definition data by creating a new GDX entity in the gdx_model model from the DXF entity definition. Will apply "gdx_mtx" to resulting GDX entity. The GDX matrix can possibly include non-uniform scaling which will alter the entity mapping for arcs and conics.

The GDX entity should be deleted using the GDX function gdx_DeleteEntity after the application has finished using the GDX entity definition unless the application intends to re-use the GDX entity.

The GDX entities that result from the DXF entities are as follows:

DXF entity	GDX entity

–
DXF_3DFACE	GDX_POLY_SHELL

DXF_ARC	GDX_ARC

DXF_CIRCLE	GDX_ARC

DXF_CURVE_FIT	GDX_COMP_CURVE

DXF_LINE	GDX_POLYLINE

DXF_POINT	GDX_POLYLINE

DXF_2DPOLYLINE	GDX_COMP_CURVE, GDX_POLYLINE, GDX_ARC

DXF_LWPOLYLINE	GDX_COMP_CURVE, GDX_POLYLINE, GDX_ARC
