Per user requests I've enabled an additional parameter for windows so that you can assign a manufacturer to the installed windows (door also coming soon). Note that the window geometry itself is not manufacturer specific but is controlled by the users preferences.
In the near future I will also be creating a window and door preset feature so various options can be pre-configured.
If manufacturer's logos are enabled in the Material tab of the Global Settings and a manufacturer is assigned then the plugin will affix a label to the window in order to quickly and easily identify the window manufacturer:


The label is actually its own group/face on the dimension 3 layer and can be toggled by turning this layer on or off.
In the future it might be useful to enable a tool that allows one to switch all of the windows and door from one manufacturer to another with the single click of a button. If a cost database is setup for the various manufacturers then the estimating module can create comparative cost estimates depending on the manufacture of the fenestration.
I've initially added the following manufacturers/brands:
Pella, Milgard, Marvin, Integrity, Plygem, Jeld-Wen, Alside, Andersen, Atrium, Harvey, MI, PGT, Simonton, YKK-AP

The label is constrained to a square 8"x8" and offsets the window glass by 0.125 so that it does not z-fight with the window glass.
Please send me any window and door manufacturers that you would like to see added to the plugin.
