Tutorial - 2D Truss analysis in Mechanical APDL (ANSYS) Part 2?

In general, a finite element solution may be broken into the following three stages.
1. Preprocessing: defining the problem;
- Define keypoints/lines/areas/volumes
- Define element type and material/geometric properties
- Mesh lines/areas/volumes as required
2. Solution: assigning loads, constraints and solving;
3. Postprocessing:
- Lists of nodal displacements
- Element forces and moments
- Deflection plots
- Stress contour diagrams

In this tutorial we will go through second and third step.

I have too many keypoints for a truss. Can I define them in an excel sheet and then import it to APDL? Can I do that?
