So I guess we can mark this as solved. Code: ```py for li,linedef in enumerate(linedefs): print(

for li,linedef in enumerate(linedefs):
    print("%d/%d"%(li,len(linedefs)), end="\r")
    vert1 = verts[int(linedef['v1'])]
    vert2 = verts[int(linedef['v2'])]
    sidedef = sidedefs[int(linedef['sidefront'])]
    sector = sectors[int(sidedef['sector'])]
    vertices.append((
        float(vert1['x'])/32,
        float(vert1['y'])/32,
        float(sector['heightfloor'])/32
    ))
    vertices.append((
        float(vert1['x'])/32,
        float(vert1['y'])/32,
        float(sector['heightceiling'])/32
    ))
    vertices.append((
        float(vert2['x'])/32,
        float(vert2['y'])/32,
        float(sector['heightfloor'])/32
    ))
    vertices.append((
        float(vert2['x'])/32,
        float(vert2['y'])/32,
        float(sector['heightceiling'])/32
    ))

for li,linedef in enumerate(linedefs):
    print("%d/%d"%(li,len(linedefs)), end="\r")
    vert1 = verts[int(linedef['v1'])]
    vert2 = verts[int(linedef['v2'])]
    sidedef = sidedefs[int(linedef['sidefront'])]
    sector = sectors[int(sidedef['sector'])]
    vertices.append((
        float(vert1['x'])/32,
        float(vert1['y'])/32,
        float(sector['heightfloor'])/32
    ))
    vertices.append((

        float(vert2['y'])/32,

    ))
