  • importing CAD models?

    could anyone tell me the best files to use when importing?
    i started using 'iges' files at first(as told by B&S) but of late been using 'step' files,as they are much smaller in comparison.

    don't have aproblem with either but it would be interesting to see what other users prefer.

    iges seems to import quicker, but there seem to be less translation errors in the step files I get, so I try to work in step.

      I have used both. In the past(7 yrs ago) IGES was what was used, but there was a few times that things went goofy. So, by that, today with the latest and greatest version I prefer .STP files. This is just my preference.

        Step, usually cleaner

          I use .step214 files. I've used .iges before, but the .step files seem to be more 'robust'....

          I like to use the SW dci I have, but it's too slow and the cad fixturing blows out everytime I use a SW model.

            I use the step files. I asked the same question some time back because I had so much trouble trying to import iges files. Never did get the straight iges import to work, had to use the iges alternate & then I had some surfaces missing.

            I asked our engineering staff about it & they wanted me to use iges because with step files you "can loose some of the nominal info". Now I double check my nominals when I work on a program because they never could get me an iges file that would cleanly import.

              I used step one time It worked ok. I use Iges all the time. If it does not import good in the normal iges, I will use alternate iges. Not to many problems.

                  Step files here. One of the biggest errors that we find is when someone converts to a step file is they do it in the wrong unit of measure. ie., a file that should have been Metric converted as inches. Iges files suck! missing surfaces etc.!

                    I like Iges. I like wire frame for my circles, and I seem to get a rounder number that does not have to be edited for dimensioning

                      I almost always use step....iges has to many problems with surfaces missing and or can't click on them. Step can have issues also but they are much fewer.

                      If you are using one package ie. Unigraphics you can get the iges flavour(settings) that work for you and always export it as the default.

                      cheers

                        Lately, I have been translating the original cad file (usually Catia V5) to .igs and .stp.
                        The .igs as wireframe and the .stp as solid.
                        Then I import both (with merge) into PCD.
                        Lately, it occurs to me
                        What a long, strange trip it's been.

                          can you tell me why you would you want to use a 'wire frame' instead of 'solid' ? as i've always used 'solid' ?

                              With the merged wireframe and solid you can complete some autofeatures with 1 click. It also makes it easier to see tangent lines.
