It is not yet possible to invert two levels in our new 3D plan tool.
To avoid having to redraw your entire plan, you can easily redraw only your floor. However, you will need to reconfigure and redecorate your level.
To begin, add a level below your ground floor.
Once you have created this basement, you can display a transparent view of the walls and partitions of another floor. You can then redraw your rooms over them. This basement is temporary.
To make a floor transparent, go to 2D Display and then Levels. In the drop-down menu, select the level you want to see. In this case, we are making the first floor transparent.
The first floor is then layered on top of your basement.
Draw your walls and partitions over this layer.
Once you have redrawn your rooms, you can delete the first floor. To delete it, go to Manage / Add levels and then Level settings.
To make your basement a ground floor (and your ground floor your floor), change your grid's reference Level.
This grid marks the level of the terrain. By default, it is set to -20 cm because it takes into account the height of the slab. E.g.: if your walls are 250 cm and your slab is 20 cm, enter -290 cm.
Your levels are now inverted.
You can rename your levels to make this clearer. To do so, go to Manage / Add levels, then Level settings.
