It's time to create arm joint (elbow) and lower for your Gundam.

Creating Elbow and Lower Arm

1. In Left viewport create box, with parameters like image below.

2. Convert box into Editable Poly. (1) Modify vertices position. (2) Select all vertical edges and then apply Chamfer with Amount=2. (3) Select lower part polygons. (4). Apply slight Extrude to selected polygons. Then, use Select and Uniform Scale tool to make selected polygons bigger (just a little bit). Adjust selected polygons position when necessary. Rightmost image shows final result. This object will be used as an arm joint (elbow).

3. Next, we are going to create lower arm. In Front viewport create closed line like image below. I create the line a little bit to the left, not the same as blueprint, because I want all objects constructing the arm stay in straight vertical line axis. When finished, apply Extrude modifier with Amount=6.

4. Convert lower arm object into Editable Poly. Select all polygons. In Edit Geometry rollout, click Slike Plane button. Slice Plane is used to cut polygons along a plane. You just need to rotate this plane. After you managed to get plane position like image below, click Slice button.

5. Change selection to Edge. Select all vertical edges in front faces (one side only, there are 6 edges you need to select). Apply Chamfer with Amount=2. In Perspective viewport, rotate view until you can see the back side. Select one polygon like image below. Apply Extrude.

6. Turn off all sub-object selection. Apply symmetry with Z axis. Move Mirror axis to fit create best lower arm shape.

7. Final detail for lower arm. Select all polygons in bottom part of lower arm. Apply Inset and Bevel..
