Looking for some help with the 1.839/1.849 distance. This callout is not a Cartesian distance . Its asking for the circumference value from point to point. I'm thinking this is going to need some combination of variables. Using 2015.1 CAD. Thanks!
Just to be difficult..... What if the diameter is significantly out of round?
Like Dph51 said, scan with a little distance between hits, then :
ASSIGN/V1=SCN1.HIT[1..(SCN1.NUMHITS-1)].XYZ
ASSIGN/V2=SCN1.HIT[2..SCN1.NUMHITS].XYZ
ASSIGN/V3=SUM(SQRT(DOT(V2-V1,V2-V1)))
ASSIGN/V4=SQRT(DOT(SCN1.HIT[SCN1.NUMHITS].XYZ-SCN1.HIT[1].XYZ,SCN1.HIT[SCN1.NUMHITS].XYZ-SCN1.HIT[1].XYZ))
ASSIGN/LENGTH=V3+V4
The uncertainty on this method should be approximately half of the density of the scan.
There is the feature type CURVE available under constructions, which has a length that can be dimensioned. With measuring points close enough it might give a good approximation.
Jefman can I ask where you got those commands from? Is there a big list I don't know about or is it all just hearing from others? Like the deg2rad command
