Door leaf undercut

David E

I generally size door openings via their leaf size as this is how I generate my door schedules, however I have issues with the ‘leaf undercut’ setting in the door parameters. Traditionally with undercuts I would expect the value of this gap to be added to the door leaf rather than taken off i.e. the wall opening size increases to take account of the whole door being lifted up to accommodate the floor finish.


Where is there a  "leaf undercut" setting ? I don't think I have seen that.

Leaf Undercut is an option you can find in settings panel for some types of doors but i think it's not available in USA version, see this post:

In France we are able to cut each door leaf 5cm upper the floor with this parameter :
