Army "initiative." Please, let us be clear about this.ĭevelopment of "commercial" CAD programs (essentially all derived from Gerber IDS) began in the late-1970's, it was supposed that the "market" for them were limited to architecture. The first (3D) CAD program that anybody today would recognize as CAD was 1979's Euclid (a "joint venture" development between MIT and a Canadian university developed under USAF and NASA funding). The first (2D) CAD program that anybody today would recognize as CAD was 1971's Gerber Interactive Design System (a "project" headed up by Dr. Government because of the USSR's launch of Sputnik. Much like old "DXF" exports from some programs, that slammed all entities onto layer 1, and even broke circles into segments.Ī little history lesson: CAD was defined in 1958's "panic response conference" held by the U.S. "if you are stupid enough to want to export to THEIR program, use this format, you complete moron, and it serves you right" is the attitide. ** A "punishment export" is a version of the target format DELIBERATELY DESIGNED to be nearly useless, but exists as a means to fill out the list. If not, I don't have one clue why they would even exist, they are charitably described as "misinformation", and accurately described as D- LIES. Now, what you are saying that may indeed be the case is that in point of fact, none of the supposedly specific file formats offered in GMD will actually produce a file any better than STEP. Assuming either of them actually has a copyright on their file formats, which evidently is NOT the case with, for instance, office software. There is NOTHING stopping corporation "A" from producing a file compatible with Corporation "B" software, other than a copyright issue, which can be overcome by an agreement between the two companies allowing "A" to output a "B" file. You folks are being a bit insulting when you jump all over me about it. It is TOTALLY REASONABLE to think that if a file format is SPECIFICALLY LABELED FOR AND AIMED AT a particular program, that it would be better than a STEP file. OBVIOUSLY when those other programs produce a file of their own format, it contains all the information. I asked whether any of THOSE, which PRETEND to be SPECIFIC, AIMED, formats, were in fact better. The question was NOT if STEP would do it, RATHER the question was whether any of the other alleged outputs were better. Here we have a piece of software, Geomagic Design, which has options that they went to the trouble to SPECIFICALLY LABEL as being for specific programs, Solidworks, Parasolid, etc. That is what I asked about, and YOU (Mibe and Lew M) have given me ZERO information about that. NOT "general transfer formats" like STEP and IGES. The point of the issue is the labeled export formats THAT GMD OFFERS AS OPTIONS. I thought I made that so clear that it was impossible to miss. I already know that the STEP file was dumbed-down and ended up as a "punishment export" format**. I am not looking for a "STANDARD" transfer file. The only one who actually provided information was DWC. I have no idea whatever about this format. I think that was so stated here on the forum.Ģ) Parasolid part. This would seem to be good, but I am told it is really only a "faked up" deal and is really just a disguised STEP file. Ignoring the above, which do not seem to be useful, leaves just a couple remaining, The potentially useful options seem to be:ġ) Solidworks part. The large number of ACIS file options I have no clue about. The STL file is even less useful than a STEP There is no option to export an actual or "faked-up" Inventor fileīoth STEP and IGES are worthless as far as conveying any information past the dumb solid.
They thought maybe a Parasolid file (they don't know), but were not impressed by the idea of a Solidworks file. The STEP format is just one "step" from being as worthless as an stl file. They basically grimaced in pain when discussing STEP files, and I can hardly blame them. The project is actually to reverse engineer some custom castings that they did not receive good info on when they purchased the company which used those parts. The customer wants files that he will have the maximum ability to use and modify after he receives them.
I HAVE received files from Inventor, but IIRC they were STEP files. I have never exported anything to Inventor, and it seems to have its own format.
