I wanted to congratulate you for the quality of the Cool VL Viewer. I have been using it since... long !
The version allowing importing dae file is very stable : no crash. Although that I do not have the technical knowledge to determine the cause of a crash
I also very much appreciate the editing window because it allows copy / paste or selective or global data of an object (position / size / rotation / shape). Very important when I start building and that I want to change the dimentions of all columns for example !
Do you foresee the possibility of copy / paste textures with offsets options ?
I wish you a good continuation and best wishes for 2013 !
