How to measure a part of curve?
-
hi,
i´d like to extract an exact distance from a curve, but somehow forgot how to do it
thanks

Well, there is C=2 pi r. If you happen to know the angle subtended by the arc, or if you know the fraction of the circle. I assume you mean true length, not Sketchup segment length(chord).

or you can just make sure that curve has enough segments (the more segments - the greater the precision), then explode it, select the segments that cover the length you want to measure, and look in Entity Info, there you will see the length.

hi ,
thanks for a quick answer, i need it to extract the curve fysically to use for another plugin.
i thought measure tool can do the magic:-)?
is there other any measure plugin for this purpose to measure a distance of wide of variety of shapes, specially need for cad purposes?
best of luck! -
hi dereeei,
thanks a lot !
a great idea, it helps a lot !
cheers! -
In all recent versions of SUp the 'Entity Info' dialog should report a selected Arc's 'true length' and NOT the total of its segments.
To test this change the Arc's segment count in 'Entity Info' and you'll see irrespective of if it's 3 or 999 the reported 'length' remains the same - whereas exploding into lines copies of that same arc with differing segment-counts will report their cumulative lengths as differing...
