Export File and view models with free software (GLC-Player) - Analyze Models using Free Tools

GLC-Player was the best free tool I found for viewing the models but its weak in generating isothermal sections and cant do isopleths. For this you need to export the model files as .OBJ files. It saves the names of the partial models. Material information and therefore the color information is saved in the .mtl file. The material must be set before exporting otherwise the model won't be colored afterwards. It does not matter which material you choose. The mtl file gets automatically exported by fusion 360 when you export an obj file and must be in the same folder so GLC player can find it.
