I'm new to Blender so bare with me. I've used various 3D-modeling software before but struggling a bit to adapt to the Blender workflow.
I have a house were I accidently cut the roof tip of. I unfortunately can't undo it since I discovered it too late and had the number of undo steps set too low. So my question is, how can I model the tip back? Can I extend the edges somehow in their current trajectory to form new surfaces? Just to be clear, the house is mirrored, so I'm only modeling half of it.
Very grateful for any tips here!
