  • pcdmis model size

    we are using PCDMIS for CMM and have direct Catia interface for our machine. my problem is the latest model i brought in seems too large for PCDMIS to handle so the graphics have slowed down to almost nothing. is there a way to reduce the model size either in catia or pcdmis to help with my graphics? right now it is unusable.

    PC-DMIS can handle it, your computer is another story. Make sure you have enough RAM. On my computers, I have 32gigs. Also, make sure everything is closed that you are not using.

      You can turn up the tessellation value in Edit> Graphics Display Window> Open GL. As you turn up the value, the model will become more faceted and won't look as good, but it will require less from your computer

        If your current value is less than 1, change it to 1 and see if it looks and performs better, then start increasing or decreasing it by about .1 until you get the balance between look/usability

      If all else fails you can view the model in wireframe. operation> graphics display window> graphic views> solid

        Import it as an iges or step

          Why would that make any difference? Shouldn't it be the same model, with the same number of features, irrespective of intermediate format?

          Not a clue if it would or not. Maybe its something with the direct cad interface that is "complicating things" ? I figure it would be a 60 second fix. If it works great, if not well, you're not out much time.

          I'm not sure how much of a difference it would make but my understanding is that there is a loss of "fidelity" when it comes to the IGES/STEP conversion. But I can't imagine PC-DMIS caring much about some number rounding.

        Could it possibly be the graphics card?

          I would let us know your computer specs so we can look at where the issue is. My guess is your video card doesn't have a lot of ram and it's resorted to using a mechanical hard drive to make up the difference.

            As mentioned above the tessellation value can have a large effect. Below shows the sizes of a 28M NX file once imported.

            Tessellation value and pc-dmis cad size
            1 17M
            .5 21M
            .1 59M
            .01 406M

            As you can see the size can get very large. Below is my graphics info. [email protected]
