What is a difference between the Fixed Geometry (Fixture option) and Reference Geometry (Advanced Fixture )? In what case i have to apply Fixed Geometry (easy to use)? In what case I have to apply Reference Geometry option? I am interested in information about applying Fixture. What are the rules? Where can I read about this? If some one can help me? I will apritiate for any help.

It is important to understand that fixtures are all about fixing degrees of freedom.

As you probably know, these are defined by 3 translational degrees of freedom (along x,y,z) and 3 rotational degrees of freedom (around x,y,z).

A Fixed Geometry fixture is going to fix all of the 6 degrees of freedom.

The Reference Geometry fixture lets you select a certain reference. This reference will be used for the direction definition. Then you will be able to fix every degree of freedom you want. So in this case a face can be fixed in one or two degrees of freedom.

In the end it's always very important to know the practical application of the component you are calculating. Because with this knowledge you are able to define the correct fixtures.

Here is a link to the SOLIDWORKS Help page, which tells you everything you need to know about fixtures:
