***E.58: The reflection about a point/segment/surface can not be used in a Macro Definition.
***E.57: Unable to derive plane of reflection.
***E.56: Unable to derive line of reflection (Zero length).
***E.55: One or more points were not rounded or beveled due to insufficient size of segment or angle.
***E.54: Lines/segments selected for the Trim Line/Segment operation are not on the same plane.
***E.53: Unable to define plane for the execution of the Trim Segment operation. The selected segments may be colinear.
***E.52: Lines to be broken cannot be prepicked.
***E.51: One or more lines have been encountered whose ends could not be trimmed (they may be parallel).
***E.50: The line selected contains an insufficient number of segments. To close a line by trimming or joining its ends, a minimum of 3 segments are required. To close it by connecting its ends, a minimum of 3 segments are required.
***E.49: A closed line selected. This 3D Line Edit operation requires an open line.
***E.48: Improper type of entity selected for a 3D Line Edit operation.
***E.47: Less than two entities picked. This 3D Line Edit operation requires at least two entities to be selected.
***E.46: No entity or improper entity picked for a 3D Line Edit operation.
***E.45: One or more of the segment ends selected for the Connect Segments operation are already connected. Only open ends of segments can be connected.
***E.44: The deletion of a segment of a face that contains a hole has been attempted, which is not allowed.
***E.43: A face or faces selected for non planar triangulation are planar and were not triangulated.
***E.42: An object or objects selected for non planar triangulation consists of all planar faces and was not triangulated.
***E.41: Triangulation can not be applied to points or segments.
***E.40: One or more faces of the transformed hole/volume contains another hole/volume, which is not allowed.
***E.39: Transformed hole contains another hole, which is not allowed.
***E.38: Opening shape (hole) contains another hole, which is not allowed.
***E.37: Unable to delete multiple prepicked entities from the same object. These entities must be selected individually.
***E.36: Shape drawn for hole/volume insertion crosses an edge of the insertion face or contains a point that is outside the face boundary.
***E.35: Prepicked holes lie on different surfaces or hole contains non parallel opening shapes.
***E.34: Opposite face for opening is non planar. Openings can only be inserted between planar faces.
***E.33: Unable to identify a unique opposite face for opening. Shape of opening may be outside or crossing the boundary of opposite face.
***E.32: Segment selected for extension is parallel to the destination face.
***E.31: Faces neighboring the face/outline picked for deletion contain inner outline(s), which will be left outside the boundary of their outer outline. Such a result is not meaningful and is not allowed.
***E.30: Outline picked for deletion is an outer outline. Only inner outlines may be deleted through use of the delete outline operation. To delete an outer outline delete the face that contains it.
***E.29: Deletion of point/segment causes the inner outline(s) that the operand face contains to be positioned outside the boundary of the outer outline. This is not a meaningful result and is not allowed.
***E.28: Deletion of point/segment results in a degenerate outline. When the operand face contains inner outlines, which is the case here, this is not a meaningful result and is not allowed.
***E.27: Deletion of point/segment results in a self-intersecting face boundary, which is not allowed.
***E.26: The segment/outline insertion to an open surface object attempted is not allowed.
***E.25: The Insert or Delete operation encountered an irregularity and was unable to generate a well formed object.
***E.24: The system was unable to identify (pick) a face for the insertion of a segment. Either the input points are not close enough to the intended points/segments or the points/segments picked are not on the boundary of the same face.
***E.23: The system was unable to identify (pick) a segment for the insertion of a point. Most likely the input point is not close enough to the intended segment.
***E.22: An input line with more than two points was entered. This is not meaningful for the insertion of single points/segments and is not allowed.
***E.21: Closed input line was entered. This is not meaningful for the insertion of point/segment and is not allowed.
***E.20: Inserting/drilling holes through solid objects is executed as a Boolean difference. In this case the operation failed for the reasons stated in the previous message.
***E.19: The input line crosses the boundary of the operand shape. The insertion of a hole into a surface object requires that the input line be closed and completely inside the boundary of the operand shape.
***E.18: The input line entered for the insertion of a hole or an opening is an open shape. This is not a meaningful operation and is not allowed.
***E.17: An insert face(s) operation was attempted, where the input line was closed and was crossing the operand face. Such an operation is executed as a Boolean union, which in this case failed due to the reasons stated in the previous message.
***E.16: The input line is completely outside or crosses the boundary of the operand face. This is not allowed for the insertion of outlines.
***E.15: The input line is open and completely outside or crosses the boundary of the operand face, which is not allowed.
***E.14: Input segment is outside or crossing the boundary of the operand face, which is not allowed.
***E.13: The system was unable to allocate more memory space for auxiliary usage.
***E.12: Input line is completely outside of the operand face boundary, which is not allowed.
***E.11: Input line intersects itself, which is not allowed.
***E.10: None of the end points of the input line is on a point or a segment of the operand, which is an open surface object. Such an insertion is not meaningful and not allowed.
***E.9: The system was unable to allocate more memory space.
***E.8: The currently picked face is open while the input line is closed. This is not a meaningful operation and is not allowed.
***E.7: One or both of the end points of the input line are not on a point or a segment of the operand. The insertion of outlines or faces through an open input line requires both end points of that line to be on the boundary of the prepicked face.
***E.6: Non planar face encountered. The insert outline, face, hole, and opening operations require you to prepick a planar face.
***E.5: The face currently picked is an open shape. Holes can only be inserted into closed shapes.
***E.4: The face currently picked is incompletely formed and/or open. The insert face operation requires you to pick a face of a solid object (well formed and closed).
***E.3: The currently picked entity is not a face. A single face needs to be prepicked for the insertion of an outline, face, hole, or opening.
***E.2: More than one entity is currently prepicked. The insert outline, face, hole, and opening operations require you to prepick a single face.
***E.1: No face is currently picked. The insert outline, face(s), hole, and opening operations require you to prepick the face where the insertion will be applied.
