Synopsis
PDX_MSGT gcr_ExtSurf(long option, MDA_PTR orig_db_ptr, double extrude_vec[3], MDA_PTR gen_curve_ptr, double v_parm, int gdx_model, MDA_PTR *gdx_ES_ptr)
Purpose
Create a GDX Extruded Surface.
Description
Given the non-zero extrusion vector (extrude_vec) and the G0 continuous GDX curve (gen_curve_ptr), create a GDX Extruded Surface. Note that the magnitude of extrude_vec is NOT limited to be 1.0.
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.
Input
option
GCR_NOVALIDATE
No validation will occur on the input data.
orig_db_ptr
The original entities orig_db_ptr as obtained from the mda_GetOrigDbptr call, or MDA_NULL_PTR
extrude_vec
Non-zero extrusion vector.
gen_curve_ptr
The G0 continuous GDX curve to extrude.
v_parm
Upper bound on V parameter. This value is -1 if gdx_ext_surf is unbounded in V.
gdx_model
The model in which to create the GDX Extruded Surface entity
Output
gdx_ES_ptr
Entity database pointer to the GDX Extruded Surface.
