Some questions about the Distance Function Object

YuTingYu Posts: 16
I am using the Distance Function to create a block model from my fault system. 
Please refer one of my previous question:
1) If I have multiple objects considered in Distance Function. Am I correct that the number I see in the end is the distance to the closest object?

2) Is is correct that Distance Function can not create a numeric model that consider the topography in the model? I tried to create the block model based on the Distance Function but it was providing a block model including the blocks above the ground.

Thanks for the answering!
