  • CONSTRUCTING A MID ARC (vision system)

    I have 2 arcs and want to construct a mid arc between them. Is there a way to take the numhits between the 2 arcs and create a mid arc between them? As of right now I just have auto points taking hits on the arcs and creating a mid point between the 2 and constructing a circle out of the mid points.

    Can you give some more information on what you're trying to accomplish?
    Based on your description, I would do it the same way, but perhaps I'm not understanding the concept.
    What are you trying to evaluate, pray tell?

      If the arcs have the same center, I would create a line that pierce each arc, and create the mid point between pierce points.
      I would then turn the line in a loop.

        This is the part, so having auto circles on the inside arc and outside arc to construct a mid arc would be ideal.

          Hi guys. Its been awhile since I have been on.. Don't they have a forum section for Vision Systems? Or am I misunderstanding the two?

            I sounded kind of douchie below. That was not my intention. I apologize for that. But, if it makes more sense, I can start posting stuff in the vision section since I am looking for a vision answers?

            Daddy don't worry about sounding a little douchey. InspectorJester is a Douche, speaking to him like that is appropriate.

            Maybe my eyesight is going, but I didn't see anything douchey, except from KIRBSTER269

          You try constructing a curve from your points, and then maybe a mid curve from the 2. just throwing that out there

            I have not but I don't think that will work. For a curve you need a minimum of 4 features. Or if its a scan, you can only select 1 scan at a time to construct into a curve. Then I don't know if it will let you create a curve because it will only think you are selecting 2 features.

            Well the idea is to do auto circles to get enough hit points to get a good average of the arc/radius on each outer edge. Then somehow be able to create a mid arc/radius. But having a loop with points is kind of a run time killer and want to avoid that. As of right now, the tolerances are lose enough where this method with just the 3 points will work and be accurate enough. But for down the road parts, I was just wondering if it was possible to do something like this.

              If a curve requires 4 features, and you have two curves, which have a total of more than 4 points, you can construct it from the points.

              That would create a U-formed curve, not a median...

            I use vector points with mid points between them like the OP said. Using Paste With Pattern makes this a little less painful for me but I haven't found a better way to do this yet

              Considering you'll probably need the radii at the ends of the slots, get the centroids of those, then midpoint a single point on inner and outer slot edges. 3 points to create a radius of your arc segment.

                Go with a profile callout. Just 86 all the mid this / mid that !

                  to answer your question directly, however, you'd have to start and end your curves in the same direction (or invert array values for one of the curves).
                  curve1 = 4point inner curve
                  curev2 = 4 point outer curve
                  construct -> point -> mid. select curve1 and curve2
                  now within that point, manually type in .hit[1] after each curve feature defined.
                  copy/paste with pattern your constructed point 3x with nothing changed
                  rename the 3 additional constructed points [1] cycling up your hit array value a digit each time [2],[3],[4]
                  voila midpoints from two measured curves
