Chapter 3 Using SketchUp to Inform Your Designs
2. If we want to trim one of the beams at 45 degrees, then we need to have a plane that
cuts it at exactly that location. This is easily accomplished by drawing diagonals and verticals
into the corner to create a face. Extend this face a little bit vertically beyond the
beam’s edges so that you don’t run into any problems when cutting.
3. SketchUp’s Intersect tool creates edges at the interface of objects that are part of the
intersection. As you can see in the right-click menu, SketchUp can intersect with the rest of
the model, a selection, or the current context. In this case, we will simply use the Intersect
with Model feature. It is important to understand that SketchUp will create these intersecting
lines in the current context. This means that if you are intersecting the grouped
beam and the face from outside the group, all lines will be created outside the group
as well. We don’t want that here because we need the intersecting lines to “score” our
beam sufficiently for us to be able to trim away the overlapping part. Therefore, before
you use Intersect with Model, go into editing mode for the beam (double-click it) and
select all of its faces. Only then right-click on them and use Intersect with Model.
