Thanks for your request, Steady Butterfly! Let me check: ① Regarding “step recognition,” what kind of steps (example: threshold between rooms/entrance raised frames/staircases/floor elevation differences, etc.) can ideally be expressed on a floor plan? ② Does an “outside floor plan” indicate a floor plan with only the outer circumference (exterior) of a building? Or is it a drawing that includes the site, garden, and exterior structure (parking lot, fence, etc.), or a drawing that also includes outdoor spaces such as verandas/terraces? ③ It would be helpful if you could tell me the expected usage scenarios (real estate listings, remodeling estimates, site surveys, facility management, etc.) and the final desired output (example: I want to include step information in DXF/OK if I can check it within the app, etc.).
