How to extract the info such as lenghts,angles and vertices from a given STEP file

I am student and new to opencascade,this might be a very basic question but I couldn't find necessary tutorials to find the answer.

Thanks in advance

You should have a look at the Open CASCADE samples. As far as I remember the qt/Interface sample shows how to import and export STEP files and qt/Tutorial shows how to do some basic geometric operations. You should read in your STEP and then iterate over the contents to compute the data you need.
