  • Google Sketch-up for speaker design?

    Ok guys. I downloaded Goggle sketch-up, and haven't been able to figure it out. Could I use it to help me figure out a cabs interior volume? My curved cab designs aren't very easy to work out, so I thought it might help. Anybody have any suggestions?

    Use the tutorials for Google sketch-up. Once you have watched about 30 minutes of those you should be able to pretty much do anything you want. It's fun to play with, for quick sketches. But it is limited in some of it's abilities to create curved 3-D objects.
    Thanks ,

      No, I don't believe it will determine internal volume of an enclosure for you.

      But it is a great tool for visualizing cab and panel dimensions before you cut materials.

        I gave up several times, until I found this:

        If you follow these videos, you'll be good to go.

        For interior volumes of irregular areas, there is a plugin that is supposed to do the calculations, but I found it didn't work when curves were introduced (it got confused because the curves were broken down into many line segments). I think volumes still require some manual calculation.

        Good luck,

          Practice, man. Practice. Sketchup is like any skill, it takes time to develop. I'm five years in to get to this point:

            If you have had prior drafting or CAD experience it's not too bad...
            Refer to your other post for my suggestions:

            Search the 3D warehouse for examples of speaker cabinets
            http://sketchup.google.com/3dwarehou...=Search&reps=3
            and examine them.

              You can certainly do some neat stuff with Sketchup. Takes a bit of planning to see the parts you want to draw to create the final shape. Might have to try drawing up that mini cab, but I know I'd have to do a little research on some of the surfaces.

                if memory serves (though you may already know this) the box has to be air-tight... a closed object, in other words don't do the cutouts for the drivers, ports...

                  No offense but sketchup is a piece of cake, I never had a problem with it. Keep fiddling with it...

                    It will give you the volume of a group. Right click on a group and view entity info.

                    This doesn't give you the volume of the "space" inside an enclosure but you can use it creatively to get what you want.

                    For instance... create a solid box with the outside dims of your enclosure. Make it a group and get the volume.

                    Now make each part into a group - braces, sides, top, bottom, and get their volumes. Do some deducting to see what's left.

                          I'm a noob with a little time on my hands. Those didn't even take very long.

                          I posted them to show that even a non-draftsman like me can render some pretty convincing stuff with Sketchup. That RSS210 and RS28 are actually pretty simple solids to build up.

                          Drawing up Ed's cabinets, especially that mini Byzy, has me scratching my head as to how to do it. I can see constructing the curved walls, but how to put a surface on the cut curve . . .

                          Perhaps there's a CAD guy snooping around to offer a suggestion . . .

                            Hi Pete,
                            Draw one side surface and mirror it using the scale tool. Then draw the outline for the back top and baffle and bottom, extrude that wider than the speaker needs to be. Then for the finale intersect them and cut away the excess to reveal your masterpiece :D
                            Regards,
                            Dan

                              I'm never again going to build any woodworking project without drawing it up in sketchup first. I've made so many small, tiny mistakes on paper that have accumulated into huge mistakes on the final project.
