This option will physically render your chosen profiles to all of the cabinet doors, drawer fronts, and panels residing in your model. CabinetSense will generate a rendered replacement for each of these items. The original artifacts (doors, drawer fronts, and panels) are hidden and the rendered replacements are made visible.
After you render, notice how the render button remains toggled on to remind you that your model now contains rendered objects. Pressing the render button again, will remove the rendered objects and unhide the original objects.
There are a number of ways that you can assign profiles within your model.
IMPORTANT: Exporting your model while your model is rendered is very different from exporting without rendering. CabinetSense exports the actual door parts (stiles, rails, panel inserts...) under normal circumstances. Exporting with rendering on, tells CabinetSense that you want to produce MDFdoors. As such, Slab doors are exported, and if you have the CNC option, CabinetSense will export any toolpath profiling layers that you might have associated with the particular profile selected.
