CreateUV & ApplyCrv

CREATEUV.3dm (55.3 KB) Hi
Using CreateUV and ApplyCrv, I have mapped the 25.0mm long red line onto the curved top surface, then measure the length of the line and it is 25.0mm

build the same thing in Rhino 5, using the same procedures and the line will measure 23.671mm

this is causing a problem as I use CreateUV and ApplyCrv a lot

please help

Hi Richie - use ShrinkTrimmedSrf on the curved surface before you start- does that look better?


Hello Pascal

I have already tried ShrinkTrimmedSrf, the line comes out slightlly better at 24.517mm

I could do this with no problems at all in Rhino 4
