I am a newbie at Blender, but love it. I am trying to create a model of a building which is to be constructed. There are several arched openings in walls. I am having a great deal of trouble being able to create these arches. I have googled but not found anything that works.
You could model the arch's shape from a plane and use Knife Project.
- Select first the arch then the wall in Object Mode
- Change to Edit Mode and apply Knife Project
After that you should have a model like:
If you want to connect the arches select them by Shift-Alt-RMB and Bridge Edge Loops
Alternativley (as suggested by Gandalf3) you could use the Boolean Modifier.
For this technique you would need to extrude the arch like the red object here:
- Align the objects
- Add a Boolean Modifier to your wall, and set operation to Difference
- Apply the modifier
The result should look like:
