How do you get data from a loop?

Adam.rgbsi
Hey everyone,

I'm still new and learning PC-DMIS. I want to learn more about looping and variables as I can see it being an important tool to make programming quicker.

So I have a round part and it has 12 tabs around it every 30 degrees. What I want is for it to loop around the part grabbing a point on the outer tab. After I want to construct a circle (best fit) and output the dia for my report.

How can I go about this?

So the code I have so far is this 
V1         =LOOP/START,ID=YES,NUMBER=12,START=1,SKIP=,
              OFFSET:XAXIS=0,YAXIS=0,ZAXIS=0,ANGLE=30
OUTER-RAD-TAB_1  =FEAT/CONTACT/VECTOR POINT/DEFAULT,CARTESIAN
              THEO/<0,-7.546,-0.15>,<0,-1,0>
              ACTL/<0,-7.546,-0.15>,<0,-1,0>
              TARG/<0,-7.546,-0.15>,<0,-1,0>
              SNAP=NO
              SHOW FEATURE PARAMETERS=NO
              SHOW CONTACT PARAMETERS=YES
                AVOIDANCE MOVE=NO,DISTANCE=0
              SHOW HITS=NO
            LOOP/END​
  • Look up offsetting alignments in a loop.
    There are a lot of ways to accomplish your goal.

    But if you are trying to construct a feature with the measured points, I would recommend paste w/ pattern over a loop.
    One input feature will not be enough to create your diameter. And I'm not sure that using the outer-rad-tab_1[1],[2]-[11],outer-rad-tab_1[12] will work in a circle construction.

    So, Looping isn't enough to catch other points? I guess I'm a little confused on what looping would be used for in this situation. I'll give what you recommended a go.
  • You can construct the circle from "OUTER-RAD-TAB_1[1..12] " directly.
    The easiest way to do it is creating a feature set selecting "OUTER-RAD-TAB_1" in the list, then ad brackets with1..12 in the edit window, and then construct the circle.
    You can dirctly construct the circle, but the demon could say that you can't construct a circle from 1 point Disappointed...

    In addition, you shouldn't use "-" in the feature name, prefer "_".
  • Looping in PC-Dmis is tricky (coming from other softwares, or other types of programming in general it's difficult to let go of this concept but it's never straightforward) -and I'm not one to say because something is difficult it shouldn't be done.

    Looping programs (measuring multiple parts is okay) but whilst looping sections of a program as you are suggesting is possible, paste with pattern is the preferred method.

    The same is true for subroutines, it's the passing of data back and forth that's prohibitive.

    stupid question but why shouldn't I use "-" in the feature name, but prefer "_"? new to programming in general.

    pcdmis is a big calculator so it may see a "-" as outer minus rad minus tab and try to actually calculate something when its just a title. So its encouraged to use "_" in the place of spaces.
