For examples of TC's capabilities take a look at the Gallery.
TC, like all CAD systems, has a steep learning curve. I started with 2D way back in V3 and moved to 3D when I felt confident and it's 3D had grown up, but now I find that its quicker and easier to design in 3D from the start, and to use the Drafting Palette for creating 2D drawings.
