Profile of a Line on Interrupted Segments

[[Ch...]]

I have a problem which seems extremely simple but for some reason is giving me a ton of trouble. I am attempting to take what is essentially profile of a line around the inside of a rectangle. The issue lies in the fixturing and sharp corners requiring it to be scanned in six separate sections. I have split it up into six line scan paths and am attempting to recall them into one curve so it can be evaluated but the tolerance is getting very confused in the corners and also is interpolating my scanned points across the gaps which I do not want. I just want a profile tolerance based on the CAD model, controlled by the drf with the actual points being evaluated to it. The attached picture is a sketch of what I am trying to do, with the green being my actuals vs the closest I can get calypso to manage it. I have tried every combination of features types I can think of, 2d lines, 2d curves, 3d lines, 3d curves.

I think you would have the best results with freeform if you have a CAD model. Just recall measured points into freeform feature.

Also you can try to mask unused points, which will result in strange tolerance also, but it will be calculated.

How are you creating the nominals for the recalled curve?

• My preferred method is using the connect nominal curves (screenshot below). This will only pull the nominals; you then have to recall feature points from the curves to bring over the actuals.
• You can also use the "re-calculate nominal geometry" option from the recall feature points pop-up. But make sure there is no actual data in your curve since it will recall the actual for the nominal data
• For both methods, I would recommend using the curve results points option when recalling the feature points.
• Another option would be to scan over those sharp corners and mask out those points. This option can be found in the evaluation window under the limit evaluation. This looks like it would reduce the number of scans to 2.
  • Maybe an even better option is using only one curve. Create the full curve. Expand the point list and delete the points that are blocked by the fixture. Lastly, create two segments with a clearance plane in between. Update the start and end points accordingly. 
    • This would be my preferred method since it does not involve any recall or combinations of curves. Make sure to make things easier by having the curve start adjacent to one of the fixture locations.
