1.Accessing tools is very easy.
2.Comparative to catia working with solid edge consumes less time for part designing.
3.Modifying the design is easy.
4.Its easy to study the design tree.
5.Drawing/sketching part is easy, you can move relocate very easily.
6.Assembling parts is much easy.
7.User friendly, most colleges prefer this software for students.
9.It does strain your body, we can relax and operate whereas when you compare with catia for each function u need multiple steps.
1. Sheet modeling is not good
2. Rendering is another drawback when you compare to NX.
3.Complex designing is difficult.
4.Not much variety of tools are available.
If your new to designing then first preference must be solidedge. If your work is restricted to part design and assembly then go for solidedge. For rendering work I suggest NX amd for aerodynamic modelling(sheet modelling) go for catia.
I used it for part designing or drawing. It help get my work done fast.
