I import a mesh(obj) into a project and edit it... when I save my project and reopen the project, my mesh is still the import mesh. Where is my mistake?
greetings iom
Use the menu. Chose: File / Export Mesh
or File / Export Mesh As
. See the Meshlab tutorial http://www.heritagedoc.pt/doc/Meshlab_Tutorial_iitd.pdf
A project is nothing more than an information structure. It doesn’t contain the point clouds itself.
