Measuring the Distance between two surfaces using ProGeomitemDistanceEval?

[Navku]

Hi,

I am trying to measure the distance between two surfaces using ProGeomitemDistanceEval method which gives output distance as 0 always.

lErr = ProSelect("surface,point,axis", 1, NULL, NULL, NULL, NULL, &lpSelectionEdge, &lSelCount);
lErr = ProSelect("surface,point,axis", 1, NULL, NULL, NULL, NULL, &lpSelectionSurface, &lSelCount);
lErrCode=ProGeomitemDistanceEval(*lpSelectionEdge, *lpSelectionSurface, &distance);

Can you help what's the wrong in this code?

Thanks in advance.

Looks like you are passing the entire array instead of its element.

Check sample code:

 status = ProGeomitemDistanceEval(p_sel_arr[0], p_sel_arr[1], &dist);

 Should be 

ProGeomitemDistanceEval(lpSelectionEdge[0], lpSelectionSurface[0], &distance)

 ?

Hi,

Thanks for the help.

Is there possible to measure the distance between surfaces without Use as plane option?

Not sure. Can you please check API "ProSelectionWithOptionsDistanceEval"

Thanks,
