Unknown operator. Please use one of these: intersection, difference, union, xor. Failed to perform boolean. Please check your data. Input data must be double vectors of the same size. Please check your data. Each input polygon must have at least three vertices. The first argument must be a string. The input scaling factor must be a positive double scalar. Input vectors contain NaN at different locations. Please check your data. Input data is invalid. Invalid facets were ignored. Input argument must be a triangulation object. Input argument must be a 2-d triangulation object. Boundaries of triangulation are not closed or have intersections. Incorrect number of input arguments. Parameter names and values must occur in pairs. Input triangulation is empty. File name must be a string scalar or character vector. File name must end with .stl or .STL. Unable to open file ''{0}''. Unable to write file ''{0}''. Unable to read file ''{0}''. Input file must contain at least 3 unique vertices. Tetrahedron triangulation is not supported. Parameter name must be ''Attribute'' or ''SolidIndex''. ''Attribute'' value must be a real, finite vector of type uint16. The length of the ''Attribute'' value must equal the number of triangles ({0}). ''SolidIndex'' value must be a vector of positive integers. The length of the ''SolidIndex'' value must equal the number of triangles ({0}). ''SolidIndex'' parameter is only supported when file format is ''text''. ''Attribute'' parameter is only supported when file format is ''binary''. File format must be ''binary'' or ''text''. ConnectivityList property of triangulation must have 3 columns. The maximum height is less than or equal to the minimum height.
