In this example I have a 2d site plan showing approx 1400 residential sections (plots, you could call them) in 2d. My task is to design the level of the finished building slab and set retaining wall heights, which I will document for the civil & structural engineers who are responsible for constructing them. To do this. I pull the building platforms up to a certain height to meet the adjacent road (the height also has a relationship to other platforms/building areas, retaining walls, driveways, battered slopes, manholes, etc). …In the screenshot I’ve hidden the roads and other info, but it’s a very complex civil design surface/mesh).
My reason for pushing the faces back downward is that, after pulling upward, I may find an issue where the slab shape doesnt work (it would make a driveway too steep, for example). To remedy this, i might need to change the original 2d face (e.g. I would shift the building slab area further away from the road to lessen the grade on the driveway).
Another common example where push-pull deletes faces that i want to keep, is when I’m pulling up walls of a house from a 2d floor plan. I would push them back down if i decide to change something in the wall (i make the change in 2d, then pull up in 3d. But pushing down usually (not always) results in the original face/edges being deleted.
I was hoping there’d be a simple toggle key for “keep original face” when pushing. Alt, Shift, etc don’t seem to work.
Also - how do you capture those cool little videos? They make things so easy to understand/explain!
