A method for transmission of data for two or three dimensional geometrical
entities uses a computer system, for modeling and/or manipulation of
geometrical entities. The computer system comprises at least one program
for modeling and/or manipulation and at least one display program, the at
least one modeling and/or manipulation program transmits the data
associated with the geometrical entities for display to the at least one
display program, by calling up display functions located within the at
least one display program. An exporting program for data associated with
geometrical entities is substituted in at least one of the at least one
display programs, the exporting program having the same display functions
as the at least one display program.
