#1347 Grey 3D view after using plug-in DimensionLines3D-4.1

[AERO38]

Hello, I've been using Sweethome 3D for more than 10 years. On a medium-sized project (5.5 MB), I've been very recently trying the plug-in DimensionLines3D.4.1 to visualize an electrical installation. Unfortunately, just after initiating it, the 3D view becomes frozen and any attempt to load the file again lead to a grey 3D view. Exporting the file on the web viewer restores this 3D view. It does not seem to be linked to the the SW installation, as loading the 'default' project allows showing the 3D view for this small project. Version 7.5 or 7.6 in 32 or 64 bits do not change the status

Hello, is there any possibility to 'clean' the sh3d file to recover the 3d view. Strange enough is that this sh3d file read on another labtop provide back the 3d view; so, it looks more related to the Sweethome3D software installation, rather than the file.
