A way to store a color and material information into step file.

UlikeM's picture

Hi, folks.

i want to store informations of color/material into step file.

but step file format not seems to save the informations.

the procedure what i did is following.

firstly, i assigned material information into each part in assembly using CAD program (i used catia v5 and solidworks 2009) and then save it in step 203 file format. (*.stp)

when i open the step file in CAD program and other step viewer again, the information which i assigned is not found.

i'm looking for the ways to save/retrieve the informations of material into/from step file.

is there anyone can help me?

thanks in advance.

I am not really an expert CAD developper but I do know that STEP definition book is several hundred pages, and all is not necessarily fully implemented, and thus supported by the CAD software you are using.

A bit less worth, but more cunning, you may have to ask for specific licenses to get these functionalities in your favorite CAD system.

Best regards,
