Generally, when you finish a complex building with doors and windows like about 40-80 rooms the operation of Dialux slows significantly. After drawing 30 rooms it is noticeable that it takes more time for the software to draw the room.

When we need to modify an existing complex building geometry that is usually a neverending story... The reason is quite simple. Every change in the contour of a space, adding or deleting a point or just moving to another location makes the software recalculate the whole geometry.

In case of a complex geometry, like a storey with about 70 rooms, including false ceilings, doors and windows this process could be more than 20-30 seconds per point.... ridiculously long time and a lot of wasted resources

My idea had been a few years ago to your developers to invent a DONE button to the end of this process. When we need to edit a room's geometry let us just draw the new shape of a new space and after pressing the DONE button the software can regenerate the whole geometry. Once... and not point by point

My opinion is that this would be much faster option than recalculating/regenerating the same process point by points
