# Synopsis

PDX_MSGT s041_GetRprCnt(long option, MDA_PTR rprcnt_ptr, int *len_unit, int *plane_ang_unit, int *solid_ang_unit, int *coord_space_dim, double *len_uncertainty)

# Purpose

Return the units, the coordinate space dimension values and the coincident point tolerance (pnt_tol).

# Description

Given a MDA_PTR to an external representation_context entity, return the units and the coordinate space dimension values and the coincident point tolerance. Note: Solid_ang_unit is there to satisfy the AP203 spec. This value will probably never be used.

# Input

## option

Option (not used).

## rprcnt_ptr

MDA_PTR to representation_context entity.

# Output

## len_unit

Length measure unit. Not set in STEP file, if value is less than 0

## plane_ang_unit

Plane angle unit. Not set in STEP file, if value is less than 0

## solid_ang_unit

Not used. Not set in STEP file, if value is less than 0

## coord_space_dim

Attribute from geometric_representation_context entity (value of 2 or 3). Not set in STEP file, if value is less than 0

## len_uncertainty

Coincident point tol (pnt_tol). Not set in STEP file, if value is less than 0.0

# Return

          S041_NOERR
          S041_INTERNAL_ERR
          S041_INVALID_ENT
          S041_BAD_DIM
