***R.33: Inproper entity selected for the controlled rounding operation.
***R.32: Unable to determine the stitch for rounding it.
***R.31: Unable to identify a proper stitch, which should be a closed sequence of segments meeting at greater than 100┬░ angles.
***R.30: No segment has been selected for the Round Stitch operation.
***R.29: Unable to derive the intersection line for constructing the end of the rounding mesh.
***R.28: Unable to generate parallel object for the derivation of the end of the rounding mesh.
***R.27: End of rounding mesh is beyond the end of the surface. Smaller rounding distance should be used.
***R.26: Unable to determine end of rounding mesh, possibly due to larger than appropriate rounding distance.
***R.25: Attempts to adjust the rounding parameters were not successful. The system will adjust the parameters up to 25% of their original values.
***R.24: Large rounding values are used which cause intersecting outlines. Try smaller values or select the Adjust To Fit option.
***R.23: One or more points of the object could not be rounded.
***R.22: Angle of segment is too wide to be further rounded. Angles of at most 165 degrees are acceptable.
***R.21: Insufficient area encountered in face while calculating the fillet parameters.
***R.20: Insufficient area or size of segments encountered on a side face when attempting to round a face or an outline. A smaller radius should avoid the problem.
***R.19: When inserting the rounding fillet on one of the end faces, it crosses other segments of that face, which is not appropriate. A smaller radius should avoid the problem.
***R.18: Insufficient area of face or size of segments encountered when attempting to round a face or an outline. A smaller radius should avoid the problem.
***R.17: Object selected for rounding has concave or colinear points. There is no proper rounding solution for such objects.
***R.16: Insufficient area of face encountered when attempting to round it. A smaller radius should avoid the problem.
***R.15: Inappropriate entities selected for segment rounding. Only sequences of segments that lie on the same face may be preselected for sequential edge rounding.
***R.14: Partly convex and partly concave sequence of segments selected for rounding. There is no proper rounding solution for such a case.
***R.13: Insufficient length of segment encountered for fitting the rounding fillet. A smaller radius should avoid the problem.
***R.12: Segment selected for rounding does not end to a single face. There is no proper rounding solution for such a segment.
***R.11: Partly convex and partly concave point selected for rounding. There is no proper rounding solution for such a point.
***R.10: Insufficient length of segment encountered while rounding.
***R.9: A hole/volume cannot be selected for rounding.
***R.8: A group of objects cannot be selected for rounding.
***R.7: Coplanar faces encountered on two sides of segment (flat corner). There is no proper rounding solution for such a case.
***R.6: Encountered point which is the end of less than three segments. There is no proper rounding solution for such a case.
***R.5: Surface or incompletely formed object encountered. The segments of such objects cannot be rounded.
***R.4: Unable to calculate fillet parameters, possibly due to insufficient area.
***R.3: Disturbed structure of reverse pointers encountered.
***R.2: Unable to derive intersection of lines. Parallel or colinear lines may have been encountered.
***R.1: Unable to redefine arbitrary reference plane.
