Difference of brepshape and directshape?

Hi,
What is the main difference between those?

thats a good question, actually i have an element, but it is either a systemfamily or a family :slight_smile:

Finally I switch to directshape node, coz the brepshape node is kinda old (maybe) and some of my geometry cannot convert by using brepshape (dont know why)
