I recieve files from vendors often and get them in either IGES or STEP file format and have no problem opening them and doing whatever it is that needs to be done with them. Recently I recieved a monster file 164MB (after conversion to SolidWorks) bout 190MB as an IGES and over 200MB as a STEP, I can open it on my machine and manipulate the assembly with little problems, however no one else can open the file due to the over all size. I have been reading the threads for a few days and have went into featureworks and yes I can add the fillets and such back on and change them. I dont need this assembly to change. if it remains static and small enough for other users to open I will be happy. Has anyone else had this problem?
