What my problem is; i want to express an if function like if P1 is out of my EG and Distance to Surface is error value OR P1 is inside the EG and Distance to Surface is a numeric value.There is the attachment to explain it.
Solved! Go to Solution.
What I would do is set an Auxiliary Point on the surface using "DeltaX on Surface" from P1 where X = 0. Then check if the new point "IsValid". if it is valid, then you can find the distance to the surface.
