%Tri is a triangulation object of a 2D mesh
trimesh(Tri) %throws error "The triangulation must reside in 3D space."
%However the following code works
pts = Tri.Points;
tria = Tri.ConnectivityList;
trimesh(tria,pts(:,1),pts(:,2),'Color','k')
%note the use of 'Color' as a Name-Value argument, Neither 'FaceColor' or
%'EdgeColor' work with this call, returning:
% Error using plot
% Unrecognized property FaceColor for class Line.
%or
% Error using plot
% Unrecognized property EdgeColor for class Line.

Since Tri is not posted, we cannot run the code or examine its inputs.

Ran in:
%attached file includes Tri object
load('trimesh_input.mat')
trimesh(Tri)
Error using trimesh
The triangulation must reside in 3D space.

Hi Ian,
The function ‘trimesh’ has an issue working with the 2D triangulation object. This issue is under investigation, and it might get fixed in the future releases.

Thanks for the feedback. The explicit workaround I noted in my original submission, means that trimesh can be used - its just not as elegant.
