After you created upper leg in previous tutorial, now you are going to create lower leg for your Gundam. Lower leg modeling will be more difficult, especially in calf area. But, I will try to use simple modeling step.

Creating Lower Leg

1. In Top viewport, create ChamferBox. Use values like image below. Position this ChamferBox under upper leg. Apply transparent material. Hide upper leg object if you want.

2. Convert ChamferBox into Editable Poly. Activate Vertex selection. In Left viewport, use region selection to select vertices like image below. In Soft selection rollout, activate Use Soft Selection. Use Falloff=42.6 and Bubble=0.86. Don't deselect anything and apply Spherify modifier in Modifier Stack. You'll get nice shape for calf of Gundam leg.

3. Convert object into Editable Poly. Activate Vertex selection. Select all vertices in top area (look at image below). In Edit Geometry rollout, click Z button right next to Make Planar. Repeat the same procedure with vertices at the bottom area.

4. Modify several vertices position based on blueprint behind. Use image below for reference.

5. Next, you are going to add more details in knee area. Activate Edge selection. Activate 3D Snap Toggle. In Edit Geometry rollout, click Cut button. Then cut in front of object like image below. When finished turn off Cut and 3D Snap Toggle. Next, activate Vertex selection. Move vertices closer to the center in Front viewport. Tips: select both right and left vertices and drag Select And Uniform Scale tool along X axis.

6. Change to Polygon selection. Select polygons like image below. Apply Extrude. Activate Vertices selection and in Left viewport move vertices based on blueprint behind..

7. Another deteail. Select polygons in front faces. Apply Bevel. Move vertices in Left viewport if necessary.

8. In Perspective viewport, rotate view until you can see top area of object. Select polygons like image below (left image). Apply slight amount of Extrude. Reduce polygon selection (middle image below). Apply Extrude three times.

9. Change to Vertex selection. In Left and Front viewport, modify vertices position to match blueprint behind.

10. In Perspective viewport rotate until you can see bottom part of object. Select all bottom polygons. Bevel 3 times. Watch Left viewport to match how much bevel amount is needed. In Left viewport modify vertices like right image below.

11. Select several bottom polygons in the middle. In Front viewport, move these selected polygons up a little bit. Then apply Extrude.

12. Activate Vertex selection. Modify vertices position like image below. When finished, turn off all sub-object selection. Try to render and watch weird faces render. The solution is to apply Smooth modifier to object with Auto Smooth active. After that, convert object into Editable Poly.

13. Create cylinder like image below. You can create this object using the same process like you did in Gundam RX-78-2 Modeling: Arm Part 2 tutorial.

14. Another details, create one Chamfer Cylinder in Left viewport. Create 2 torus object also in Left viewport. Use values like image below. Position Chamfer Cylinder in the middle of two torus. Note: Chamfer Cylinder can be found in Extended Primitives drop down list, and Torus in Standard Primitives drop down list.

15. Image below shows finished upper and lower leg.
