For the reconstruction of the coffin box I used the same file and collection as the coffin lid. I added a new cube in object mode ((Add –> Mesh –> Cube), and changed the dimensions of this cube again (x= 0.54 m, y= 1.90 m , z= 0.25 m). For the bottom I once again used my 0.3 m cube and scaled the coffin box in edit mode. I the added four loop cuts (from the toolbar on the left hand side) and moved them with the shortcut G-G. I then scaled these edges along the X axis (Image 1). After selecting all, I subdivided the coffin box four times. Then, from top view and in wireframe shading and being able to see the model of the original coffin lid, I selected the edges and scaled the along the X axis to fit the head form of the top part of the coffin (Image 2). I then selected the second row of edges at the top part to move the slightly, to create a thick edge for the coffin, before extruding selected faces inside of the coffin to create a 3D coffin box. Because the inset extrusion created faces that didn’t correspond to the outside faces, I used the loop cut tool and added non loop cuts to the inner part of the box (Image 3). While using the original coffin part and the reconstructed coffin lid, I used the knife tool in wireframe shading on the coffin lid, to create edges and faces so I could inset the faces and create holes for the fasteners to fit in. Here I once again after creating the faces, selected all four, to move all the same time, inset the slightly, extruded the into the model, then scaled them on the X axis while remembering to select Individual Origins for the Transform Pivot Point. Now both the coffin lid and the coffin box are reconstructed (Image 4).
