![]() Her website, offers a wide variety of learning materials for all ages, from kids in grade school through design professionals. If you’re feeling ambitious, you could find a digital image of the face you want to use, trace over it with line and arcs, and use those objects for the carving.īonnie Roskes has been writing tutorial-style projects on 3D modeling software, primarily SketchUp, since 2001. There will be a few edges to erase as well. Now comes a bit of painstaking work – erase faces one by one, both outside and inside the shell, to make the holes. With the intersection edges created, you can now erase the group with the face objects. Right-click on anything that’s selected, and choose Intersect Faces / With Model. Orbit around and make sure the objects go back far enough to intersect the front of the pumpkin. ![]() Group these objects, so they’ll be easy to erase later. Draw a rectangle off to the side and use the Line tool to draw on that rectangle the shapes you want to carve into your pumpkin.Įrase the rectangle, and Push/Pull the objects you drew for the carving. Switch to Front view ( Camera / Standard Views / Front). So to make things simple, explode everything once again, till you’re down to just loose geometry. The Shell extension adds a group inside the group you already have. So I dropped a section plane ( Tools / Section Plane) to slice the pumpkin, to make sure it’s shelled. Of course, since the pumpkin is closed, you can’t see the results of the shell. Then double-click to complete – that’s all there is to it. I used 10′, a rather thick shell, but it makes sense for a 240′ tall gourd. Now let’s shell: select the pumpkin group and choose Tools / Shell from the main menu. If you haven’t installed extensions before, see our intro post on how to do it (it’s easy).įor Shell to work, you also need to install ThomThom’s TT_Lib2 extension. (There are other ones you could try, like Joint Push Pull, but Shell works great for this example.) So I’m going to use ThomThom’s Shell extension. But I want mine to have a thickness, like a real pumpkin. Right now the pumpkin is a hollow, paper-thin shell. The Shell extension only works with groups or components, so make a single group from the pumpkin faces. So explode and explode and explode until you’re left with just loose geometry – ungrouped edges and faces. This model is made up of lots of nested components. Now I know about how thick I want the shell to be. I’m not going to bother changing the size, but later I’m going to create an inner shell, so a sense of scale is useful. This scale of this model is rather huge – I measured a total height of about 240 feet. The one I used for my jack-o-lantern is this one:Ĭlick the “3D Warehouse” logo at the lower right corner to find this model’s download page. There are many pumpkin models in the 3D Warehouse. How about a Halloween SketchUp project? Grab your kids – they can do this one as well.
