Synopsis

PDX_MSGT gdx_ConvertSolidToCBS(long option, MDA_PTR gdx_solid_db_ptr, int model, MDA_COUNT *num_of_curve_faces, void *gdx_curve_bounded_surfs)

Purpose

Convert the faces in a GDX solid to GDX Curve Bounded Surface entities

Description

Given a GDX solid entity, converts the GDX face entities to GDX curve bounded face entities.

The GDX solid entity and all its subordinate entities must be valid definitions.

Input

option

GDX_COMMIT

Commit the GDX Curve Bounded Surfaces to the database and return the MDA_PTR database pointers. Otherwise the memory structure pointer for the new GDX Curve Bounded Surface entities is returned.

GDX_REMDUPEDGE

Remove any duplicate edges (Edges with the same Vertex end points and opposite sense). This option will remove the edges that lie along the seams of closed surfaces and thus remove the seam edge curves. This may result in a change in the number of boundaries (Loops to Composite Edge Curves). Potentially a Curve Bounded Surface may result with the only boundary being the original boundary of the surface (num_of_bounds == 0 && first_is_outer).

GDX_CHKSENSE

Check the sense of the model and parameter space curves relative to the surface and update when in error

GDX_KEEPNORMAL

Force the CBS normal to be the same as the original topological normal.

gdx_solid_db_ptr

The GDX solid entity database pointer

model

The model number for creation of the new GDX curve bounded face entities.

Output

num_of_curve_faces

The count of GDX Curve Bounded Surface entities

gdx_curve_bounded_surfs

The new GDX Curve Bounded Surface entity structures or database pointers

Return

      GDX_NOERR
      GDX_ENTITYNOTSOLID
      GDX_NOMEMORY
      Low level error return
