Convert IGS Format 3D Model File into IGES format

Hi all, We have a selection of 3D Models in IGS format which we need to be converted into IGES format. Our designer is unable to render the files into the correct format. The format required is IGES and must be able to be opened by a manufacturing company for use on CNC machinery in order to create a mould. We have 5 files which need to be rendered correctly into IGES format and with the following requirements: 1) Files must be under 30mb in size 2) File must show skins and surfaces on the model - at present our models do not show this when rendered into the current IGS format. 3) File must be IGES format 4) File must be able to be used as a working model to create production moulds from. This will be a very simple job for someone who knows what they are doing. We will send you our 3D Model files once the job has started. We are looking for a fast turnaround on this and no hassle. So please ONLY bid if you KNOW you will be able to open the IGS files we have and convert them into IGES files, apply skins and surfaces and make them under 30mb. We don't want to keep going back and forth with the manufacturer so PLEASE only bid if you can do the above successfully. We look forward to working with you soon!
