Having seen rebuild alter a curves accurate path I am a little cautious of this command. I have a curve with 19 points, it was 13 until adding a required extension either end for surfacing before trimming it back down to original length.
I select the curve, run rebuild to just consider it and I note the deviation 0.003, and decide not to run it, then revisit it within a minute or so and consider it again as 0.003 I decide is ok, yet this time it says 0.005, same settings as before.
Hope to hear what is going on with rebuild tool here. When starting out with rhino my first ever use of rebuild saw it alter a curve more than I dare let it as that then messed up the aerofoil section more than was suitable.
Following a revisit to this tool only to spot two different deviations on the same curve. and the start of this post,…
I have now a much more worrying occurrence, yet try again and sanity returns.
first time it declares 0.8mm change to my profile, now as you can see thats a drastic change, this wouldnt fly !
try again a while later and only 0.01 and no alarming curve shift.
I have come back to having to consider rebuild as its right and proper to sweep curves with same control points.
I have one curve with 42, another it says segment 1 control point 5 segment 2 has 6 and so on.
so either a case of adding them all up to see what I have or rebuild it.
I have worked my way through all my curves using 13 and 3, so as to sweep them.
