<translate> In order to Access to Single Point in the Feature it is necessary to use the command PTDATA/.

In this example it is shown how to read a measured point of a feature.

$$ Measuring a Circle with 3 points

F(C1)=FEAT/CIRCLE,INNER,CART,0.0000,0.0000,0.0000,0.00000000,0.00000000,1.00000000,20.0000

$$Declaring the necessary Variables

DECL/DOUBLE,xx,yy,zz,ii,jj,kk

DECL/CHAR,100,st1

$$Get the number of points measured in the circle using the function PTDATA/

npt1=ASSIGN/PTDATA(FA(C1))

$$Loop within the number of points and Copy the raw points in an sequence of New point Features
$$The access to each individual feature is made with the commandFA(name)[numPoint]
