ive got a problem from college.

i have to look at and find out about igis files and there use in programs such as alphacam.

I think igis is a type of file that is old now and not used today it has been replaced by dxf files i think am i right any info would be helpful ?

IGES certainly is used, and could almost be considered a de-facto 'standard' cad format. It's not great, and I think its a major oversight by autocad for not supporting it, but its widely supported by nearly all other CAD/CAM programs. If you want to be sure that the file your sending to someone is 'openable', you use IGS. STEP is a second choice if available, and DXF is a very distant 3rd.
 
IGES files are an old format for cad. IGES as well as DXF are different formats that CAD programs attempted to use to provide some way of transferring graphic (drawing) information from one system to another. DXF (and DXB) was actually developed by AutoDESK.

The problems in using such a system is that graphic information in different systems was different. (duh) Problems arise when one system can only use numbers for layer naming or colors which are usually identified by numbers are different between systems. Or "layers" may be called "levels" in another system. This only a few things that can be different between CAD programs.

So, in essence, these formats became filters. They only seemed to work well when two different cad programs used similar graphic information criteria. Also, the conversions only seemed to work as well as the conversion software. Most of these conversions were custom-made third party software that were granted rights to access the CAD databases. Which may have worked well at one level but, when either cad system went through an upgrade the conversion may have became outdated. The other thing is some CAD systems did not want to devulge the way they kept their databases (graphic information)

I hope this was of some help. Good Luck!!
