# Synopsis

PDX_MSGT gdx_FaceSplitCCParmCurves(long option, MDA_PTR gdx_face_ptr, double devtol, long maxits, int fitdeg)

# Purpose

Split all edge curves that contain composite curves as parameter space curves for a face.

# Description

Check all Edge_Curves for parameter curves that are Composite Curves. If any are found, split the edge into multiple edges, insert the new edges into the required loops, and generate the new verticies where needed.

Generate missing parameter space curves for the face.

# Input

## option

Options (Not Used)

## gdx_face_ptr

The database pointer for the GDX face entity

## devtol

The deviation of the model space image of P(s) from the projection of M(t) should not be greater than devtol. This tolerance should be larger than MODEL_SPACE_PNT_TOL, at least by 1 to 2 orders of magnitude.

## maxits

Maximum number of iterations. Iteration will be stopped if this number is exceeded.

## fitdeg

Degree used for fitting. See option GDX_FITDEGMAX above.

# Output

## gdx_face_ptr

An updated GDX face with parameter space curves

# Tolerances

          MODEL_SPACE_PNT_TOL
          PARM_SPACE_PNT_TOL
