Synopsis

PDX_MSGT gcr_Polyline2(long option, MDA_PTR orig_db_ptr, MDA_COUNT num_of_pnts, MTH_3DPNT (*points), int gdx_model, MDA_PTR *gdx_PL_ptr)

Purpose

Create a GDX Polyline.

Description

This function may create a one or two point polyline, since no point or line entity exists in GDX.

If the polyline contains more than 2 distinct points and the first and last points are within the point_coinc_tol, the GDX polyline is flagged as closed.

If the points are found to be planar within the current coplanar_tol and the definition plane is an XY plane and the Z distance is <= coplanar_tol then the GDX polyline is flagged as XY planar and the Z coordinate value is ignored.

The orig_db_ptr argument should contain the database pointer of the entity that the new entity was created from (usually this should be obtained by the calling routine via mda_GetOrigDbptr) or MDA_NULL_PTR. See the mda_intro man page for more information about predecessor entities.
