This model took quite a while to create, but it was definitely worth it. With this model you will be able to use 1 window model to create all of your various standard aluminium window sizes when working in Blender for archviz. The two most important things to note are: if you are going to use a different rendering software like I do, remember to apply the geo-node modifyer, otherwise materials will not be applied. Secondly, I am unsure wether the geo-nodes were able to transfer to the various model types uploaded (I dont think so), so be sure to use the Blender model to create the different window types. All of the windows are based on 300mm intervals (based on standard window sizes in South Africa). Bear in mind that poly/vert counts may differ depending on the window size you choose. These windows also work well for game creation needs. Enjoy!
