Good morning! I am adding an arched metal roof to a building I’m designing. The arch part was very easy. I drew an arch over the building, offset it 8", closed in the ends, then extruded that face the length of the building. NOW, at each end of the roof I want to pull the top of the arch out 6’ to 8’ to add a little more flare. Thats where Im stuck…Ive tried everything I know to do with no luck…Help?
Depending on what you need you might be able to use the Scale tool. Or it might just be easier to draw a new arch. If you shared your SketchUp file so we can see what you’ve modeled and what you need to do it would help.
Another option for doing this involves using the Solid Tools. This requires that you make your roof a solid group or component and then model a"cutting" volume. Subtract then subtracts the cutting shape from the roof.
The neat thing about this option is that it can be faster and it makes it easier with more complex shapes. Example although not a roof. The yoke of this U-joint was initially a round volume with the necked down back end. I used cutting volumes to create the outside end of the yoke as well as the inner shape.
Putting geometry in a group container protects it from being modified by other geometry. Notice in my example using Intersect Faces the geometry for the roof and the cutting face are loose geometery. In other words, in the same context. If you want to use the Intersect Faces method and you’ve grouped the roof geometry, you need to open the group for editing and add the cutting face geometry.
To intersect with a group it is often easiest to draw the intersector at the exact place but outside the group, using inferences to locate and align it. Then copy or cut it, open the group and do paste in place. Do the intersect while the group is still open.
