« AutoCAD 3DSOUT is back In | Main | Revision Clouds... »

The nice part about a DXF file is that it allows exchange to other systems, programming, or data parsing all in a documented exchange format. DXF has been a good method for over 20 years now.

This is great for vanilla AutoCAD, but what about for verticals?

With the big push to get everyone off of AutoCAD and onto verticals, how will we share this data with non-Autodesk users?

You can't read or write an LDT, C3D, or ABS drawing that contains objects using DXF.


Because ObjectARX entities rely on ARX libraries they are not able to be read unless the developer has written an enabler or the person is using the product they were created on. You can convert the custom object to plain geometry with some commands or save it with a proxy so the objects can be read and viewed but not modified. There are ways but certainly not everything when dealing with custom objects or data rich models is simple or able to be a structure another system will understand. It is a difficult issue but one many are looking to make easier instead of more complex as the data models get richer.

This is also a technology hurdle or double edge sword as I see it. As technology and as industry demands for richer data models it grows the data complexity and perhaps the possibilities or paths to addressing it. To have a one size fits all schema or a way to make it exchangeable without limiting the richness of the data is no easy challenge. If you think about many things get more advanced, more controls, more data, and more options, they usually get more difficult. Just look in a cockpit of a jet (any brand) compared to a car. Perhaps not a perfect analogy but I have formed my personal opinions based on having seen the design world from the end user and from within a software company and designs computers and technology sure has changed in the past two decades. There is also the problem of many companies strongly thinking in different ways to accomplish things and each is fully committed to their methods are best for one reason or another. There are many software vendors, experts, disciplines, formats, schemas, standards, rules, laws, strategies, codes, working groups, associations, opinions, and then add industry concepts like BIM and the multiple ways to accomplish that. All this makes me sigh and cringe at the problem of how all the different parties can agree without just the easier choice of doing what is in the best interest of their customers and products without a potential boat anchor slowing down innovation in the interest of some other company. No simple solution currently, I wish there was.

thankyou for the chance to enjoy the atutodesk
