  • Scanning for noobs

    Hey, I have never used a scan before and would like to learn. I haven't taken the level 2 course with hexagon yet. I am just wanting to get a head start.

    Is there a proper way to start a scan?

    Does anything in the scan window need changed? Does it depend on the material type and what not?

    If there is a basic guide to scans or a document i could read, please send my way.

    Thanks in advance everyone.

    What kind of probe are you using? Do you have an analog scanning probe or just a TTP?

    Also if you have CAD you can use to practice on a test part then it'll make it a little easier on you

      ajlee7 it is an analog scanning probe. We don't use actual CAD, we use IGES to insert into PC-DMIS. Is there a good way to start practicing with it? I have zero experience on how to scan anything. Maybe a step-by-step or a training guide you know of?

      Cad is generic for a "model". So yes, you use CAD. I wouldn't even now how / where to begin on trying to explain scanning from step 1....

    Just to add, since you are obviously quite "green" at this, IGES is a CAD format that PC-DMIS uses. Depending on which version of PC-DMIS you are using, there is a wealth on information in the help files regarding scans. I myself have been using scans for about 3 years now and have never had a level 2 class. Many parameters need to be modified dependent on the scan type and the input available.

      I'll have to second Jim on this. The help files are probably going to be the most useful thing to you at this point. Scanning is a pretty significant topic (hence the existence of the dedicated class).

      If you're set on self-teaching, the best thing to do is just dive in.
      Load a part with a round feature, and try a basic circle scan (Insert>Scan>Circle)
      Just input the parameters for that circular feature (Center XYZ, diameter, inner/outer), don't worry about the cutplane for now, if you leveled to a plane parallel with the feat then it's fine.
      If you have a model for the part imported you can see arrows on screen for where the scan will begin and end.

      Once you can get that one try a linear open or linear closed
      Good Luck!

      p.s. scans can't directly be dimensioned as they are just a collection of points, so you'll have to construct a feature out of the collected data

        The junior member tag on your profile is misleading. Much help! Thanks.

      on the PCDMIS help file, look up Scanning tutorials. It gives a lot of info
