I answered a question recently about drawing sliding dovetails in SketchUp. I wound up making the attached video to show how I do it. It’s quick, easy and painless and everything lines up perfectly.
There are a couple of key things with my process.
- Every part is a component and if they are identical, copies of the same component.
- Every part is drawn in place where it will live in the model.
- The shelves are drawn to their full length.
This method would also work nicely for simple dadoes and it isn’t a big stretch to see that the same process would work for either half-blind or through dovetails on drawer boxes or cases, box joints, bridle joints and so on.
There are settings under Window>Model Info>Components that allow some or all of the model to be hidden while editing a component. If you use that, you’ll have a little more work to do in laying the joints out because you won’t be able to use the other parts as guides.
Addendum: David5346 asked, in the comments section, about sliding dovetails. Here’s a quick and dirty video to demonstrate making a sliding dovetail. Pardon the stammering. This was the first run through.
