One thing, that is preferred, to have in simulation features for Fusion is to have the flexibility as well as the robustness and quick modeling tools. Some CAD modeling software tools have features that are too rigid and users can't change the modeling feature that much or easily. On the othehand mainstream modeling software tools are very comprehensive and felxible, so it needs more time to set up a model. The compromize is not easy. The idea suggested here is to provide both paths in Fusion, may be the quick modeling features first, and later the more flexible comprehensove ones.
