Legs 1 (Fig.21)
-Create a vertical edge loop as indicated in the figure
-In Edge sub object mode, Pick Create from "Edit Geometry" and click on the 2 vertexes in the figure, this will create an edge that separates the lower belly from the thigh.
Legs 2 (Fig.22)
-Move the indicated vertexes forward to start creating the upper thigh.
-Select the faces under the thigh.
Legs 3 (Fig.23)
-Use the Extrude dialog box in Face sub object mode, and use a value of about 0.30m
-In Vertex sub object mode, reshape the thigh as shown in the figure.
Legs 4 (Fig.24)
-Create another edge loop which splits the thigh vertically (check figure)
-Reposition the new vertexes in order to shape the thigh section in a sort of chamfered rectangle. This will give us a good section to keep extruding the leg.
Legs 5 (Fig.25)
-Extrude the leg section about 0.60 m.
-Create 2 edge loops around the leg.
-Shift the top edge loop up to create the knee area.
-Shift the lower edge loop down.
Legs 6 (Fig.26)
-Choose an Orthographic view from the Right.
-Press F3 to view the model in Wireframe.
-Turn on Snap (press S). Change the Snap to 2.5 Mode (Left Click on the Snap button and pick the 2.5 option). This way the vertexes will only move parallel to the screen space.
-Align all the vertexes on both sides of the leg by dragging them to the nearest vertex.
With the vertexes aligned, when we use a selection window we will be sure to be selecting the vertexes on both sides of the leg.
