  • Large cad files (800+mb)

    Does anyone else have issues with large cad files (files over 800 mb)? I am using a catia translator and I am having major issues with these files once they are imported (have been for a couple of years now). We have well over the recommended memory/ram, etc. to handle these files but I am running into countless errors etc. and was just wondering if anyone else has found a solution to these types of issues?

    (smaller cad files! snicker!)

    Well, have you tried dividing the cad files into smaller segments, program off one segment, then replce the cad, then repeat? Pain in the rump, but it might be a possible work-around.


    Here's a tricky idea for you (don't know if it will work), have the cad guys chop the data into, say, 4 sections (approx 200mb each), then make a Pcdmis program that is nothing more than data, ie PART-CARP-SECTION-1-DATA (yes, I used MINUS, not underline!). Then, once you have these 'data programs' for each section, make your real program and do a CAD REFERENCE IMPORT from each, see if that will help. It should give you the look of ALL the data but with a VERY small .CAD file for the program.

      What exactly is your problem? Is it slow to pull up?

      I found that models converted in V4.0 and earlier, pull up really slow in V4.1. The only solution I found was to re-convert the model using the translator that comes with V4.1. Delete the old model and then re-load into your program. That sped my system up by 95%! Went from 45 seconds for a 50 Meg file to less than 3.

        Normally I deal with a lot smaller files (50-150mb), which I do not mind at all. It's just the assemblies that I hate dealing with.

        I'm working on that now. What a pain in the rump that is. At least I get paid by the hour and not the job...

          I'm trying to import it in 4.0 (the latest version we have on the machine that has the cad translator). Copy the file to my machine P.C. and open it in 4.1Beta. Once the file opens I get a serialization error???

            I found that the problem exists all the way up to V4.0. So if you were to translate your model in V4.0, you still have the problem. The only thing that worked for me was translating through V4.1. I have reported this problem to Hexagon under PR 245555. No answer yet.

            They changed something when going from V4.0 to V4.1. I re-converted my CAD files using V4.1, and all problems were gone. They load quick and painlessly.

            I do not understand your serialization problem. I never had that.

              I'm not sure why I am getting the serialization error either... Looks like today is going to be a day full of experimenting. I'm going to try installing 4.1Beta on the machine with the translator to see if that helps any.

                longer still?

                We just received our 4.1 upgrade discs. (We stayed with 3.7 mr3 and tossed the 4.0 discs because of all the bad feelings with the version.) Are you saying that the programming to CAD in 4.1 (i.e., importing and programming) is going to take even longer? My lord.....when I do large CAD files now, between the importing and regeneration between program entries I'm knitting a quilt as it is. Any suggestions?

                  One of our 3rd party houses receives the files in an .exp format. I assume they are using some type of cad software to shrink the files down. For example: when I use the catia translator to import a file the size is approximately 800mb, the exact same part in their program is approximately 150mb? Anybody know anything about .exp files or the cad program that would be able to shrink the files like this?

                    We import with 4.1 and then program with 3.7MR3... works great.

                    What a long, strange trip it's been.

                      .EXP is a Catia Export File, it is only available in Catia. There was another software out there at one time that could do this as well, but, I don't know the name of it anymore. EXP is also associated with the Step Express Schema which is another offshoot within Catia.

                      Unless you have Catia, I think you might be out o' luck unless your customers would help you out with them.

                        What I do with large assembly models,
                        is open the assembly in Catia and write each individual part I need out in the assembly coordinate system.
                        This allows me to bring the parts into PC D-MIS one at a time so it does not bog down the system.
                        They are all in the assembly coordinate system so they pop in, in the correct place as long as you do an iterative alignment to the assembly coordinate system with the first part.
                        Works rather well, if you have access to Catia or similar software or can request it from your customer.
                        Note: I had looked at V4.1 and was impressed with the ability you have to manipulate assemblies from within PC D-MIS,
                        I'm still waiting on IT to install V4.1 on a PC with a machine, so I can test it out on-line.

                          I'm using 4.1 but have not tried any of the manipulation of the 3D data. Maybe I should be looking into that because we no longer have access to Catia at our assembly plant (where I'm at). We use to have 3 designers in plant and we used to have a Catia workstation in the CMM room. Due to budget cuts that is all done at our headquarters now by several different designers that are 4 hours away.
