Describe the procedure to perform an Interfence Analysis in an assembly
1. Drive constraint 2. Expand dialog box, check collision detection, than drive constraint
List three differences between parametric modeling and traditional 2d
2D is Auto Cad Parametric is 3D 2D is size before shape parametric is shape before size one is 2d, parametric is 2d 2D has no relationship between features Parametric has relationship between features.
What are the advantages and disadvantages of creating fillets using the 3D fillets command and creating fillets using in 2D profiles?
3D fillet can be put on any edge, more feature 2D fillet depend on the profile and the last feature.
Describe the elements required in creating a Swept feature

What does CSG stand for?
Constructive Solid Geometry
Keeping the History Tree in mind, what is the difference between a cut with a pattern and cut each one individually?
Cut with pattern get one feature Cut individually gets multiple features

How do we distinguish from derived dimensions and regular dimensions
Derived cannot be modified and regular can be modified.
What is the main difference between dimensional constraints and geometric constraints
Dimensional controls size, geometric controls shape.
How do we end the edit mode and return to the assembly model in Autodesk Inventor
