Carport designed in Fusion 360. Model history is recorded - model is editable, so You can adjust the dimensions to Your needs: e.g. boards' thickness/width/spacing, overal width/length, interior width, length, height etc.

Wooden boards and pillars are solids, cut to each other.Sheetmetals on the roof have no thickness - they are surface objects.All the geometry consists of flat areas (without any roundings), so there will be a low number of polygons after meshing.

Materials used from Fusion360 library - solid pine wood and powder coat textured black (as seen on screenshots). The native file looks and renders in Fusion 360 as seen in preview pictures.Some formats (like stl, iges and step) do not contain material info.I do not know if/how the other formats exported from Fusion 360 will use the materials and how they will look like/render in other software.
