Error using LazySets.plot3d

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

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

MethodError: no method matching iterate(::Polyhedra.Mesh{3,Float64,DefaultPolyhedron{Float64,MixedMatHRep{Float64,Array{Float64,2}},MixedMatVRep{Float64,Array{Float64,2}}}})
Closest candidates are:

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

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

LazySets.plot3d (see definition here) calls Polyhedra’s mesh. Did you try plotting commands from Polyhedra directly? E.g. all the examples in the section 3D Plotting with Plots.
