I even did Pkg.update() to ensure i have the latest versions, but still get t

```julia
using LazySets, Makie, Polyhedra
LazySets.plot3d(10. * rand(Hyperrectangle, dim=3))

```

```julia
MethodError: no method matching iterate(::Polyhedra.Mesh{3,Float64,DefaultPolyhedron{Float64,MixedMatHRep{Float64,Array{Float64,2}},MixedMatVRep{Float64,Array{Float64,2}}}})
Closest candidates are:
  iterate(!Matched::MutableArithmetics.Zero) at C:\Users\<USER>\.julia\packages\MutableArithmetics\NuiNA\src\rewrite.jl:78
  iterate(!Matched::MutableArithmetics.Zero, !Matched::Nothing) at C:\Users\<USER>\.julia\packages\MutableArithmetics\NuiNA\src\rewrite.jl:79
  iterate(!Matched::DataStructures.TrieIterator) at C:\Users\<USER>\.julia\packages\DataStructures\DLSxi\src\trie.jl:112

The code works for me (see below; I also wrote @time to measure the “time-to-first-plot”). Maybe it is an issue related to your installed versions? Can you please try

```julia
julia> using Pkg; Pkg.status(["LazySets", "Makie", "Polyhedra"])
Status `~/.julia/environments/v1.5/Project.toml`
  [b4f0291d] LazySets v1.38.0 `~/.julia/dev/LazySets`

thanks, here’s what i get, only Polyhedra is of different version at my end - will get the v6.11 and post results again

```julia
Pkg.status(["LazySets", "Makie", "Polyhedra"])
@time using LazySets, Makie, Polyhedra
@time LazySets.plot3d(10. * rand(Hyperrectangle, dim=3))

```

LazySets.plot3d (see definition [here](https://github.com/JuliaReach/LazySets.jl/blob/master/src/Plotting/mesh.jl#L117)) calls Polyhedra’s `mesh`. Did you try plotting commands from Polyhedra directly? E.g. all the examples in the section [3D Plotting with Plots](https://juliapolyhedra.github.io/Polyhedra.jl/dev/plot/#D-plotting-with-Plots-2).
