1. Select the face creation tool and draw a face using the contour lines of the top of the head to the base of the ears.
Since MarbleCLAY only supports quadrilaterals or triangles, only edges are created without faces on pentagons or more, but these edges can be used as guides for face creation, so leave them as poly lines or guide lines for now.
Please note, you are joining the top of the elephant body outline (1) to the ear outline (2) and to the truck (3)
The face created is more then 4 points, so no face is created until it's broken in to two smaller faces.
(The explanation is difficult to understand, but please click in the order of the numbers in the figure and press the Mode cancel(Esc) key at the end)
2. Next, from point (5) in the image above, click point (1) to point (2) as shown in the image below, the edges will automatically split to create two faces, quadrangles.
Mouth
1. Create the mouth part in the same way as the trunk.
2. Connect the mouth part and the base of the trunk with the face face/UV weld(3) tool.
If the 3D mesh becomes confusing and hard to work with, and it is difficult to select vertices, you can display the 3D magnifying glass by selecting [Window menu]->[View 3D Loupe] to enlarge the area around the cursor and select vertices. will help you.
Ears
1. Create the ears in the same way using the face face/UV weld(3) tool.
2. Select the extrude Extrude(7) tool (with the option set to "Extrude with backside") to add thickness to the ears.
(Remove the internal facing faces of the ears in the same way as the feet and trunk)
