![]() ![]() () Click ok to set the resolution of the template file. See Wikipedia for more examples and a more in-depth explanation. Does this matter to you? Probably not, but unexplained things bother me. These coordinates are used to tell the program what part of your finished image gets placed where on the 3D model. Instead of confusing the coordinates of the 2D template by also calling them X and Y, the letters U and V are used. The 3D model is already using X,Y and Z to describe itself. What are UV coordinates you ask? I had to look it up too. You will get this warning message that is telling you that Pepakura Designer will create new UV coordinates for the model if you click ok. Below is a picture of the menu since this can be confusing. To generate the template, go to the File menu -> Export -> Texture Editing -> Map Image for Texture (*.BMP). The filled in coloring is easy to do in any paint program if you have the template to follow. Along with the barn star we are making, this is a great starter project. The Gift Box pictured above is a nice one-page design with a full color lid. A simple example of this can be seen in the sample files that come with the app. Those models do include colors and textures that come in with the model. This is also why Pepakura Designer supports 3D file formats that are used by the computer game industry. That is not what the format was designed for. One of the things that STL files do not do for us is carry textures and colors. But with Pepakura Designer you can do much more. You could print this as it is and you would be done. Just that easy you took a complex shape and created a paper model. To create the 2D unfolded version, click on the “Unfold” button located at the top center or select “Unfold” from the “Other” Menu. Now you have the 3D version loaded on the left. It does not hurt the file and if you end up with something you did not want, just load it again. If you want to see what the app is asking you can click your way through the dialogs. For the barn star it does not really matter, so click “Close” on the first box and “OK” on the boxes that follow. This is so that the 3D version looks like you expect it to. As a result, Pepakura Designer takes you through a series of steps to orient the object. While it may seem odd that 3D programs cannot agree on which way is up, it is a fairly common problem. I just always let it auto detect and have not had issues. You will be asked if the file you are loading is ASCII or Binary or if the app should auto detect. Things with curves in particular are more complex to handle in Pepakura Designer. There are a lot of STL files available and STL files are easy to create, but not all STL files work well as paper models. STL files are one of the 3D object file types that Pepakura Designer handles. ![]() Load the Barn StarĬlick on the file folder icon in the top left or select “Open” from the “File” menu to load the barn star. The 2D area shows the unfolded pattern and allows you to make changes to the pattern to better fit your object on the paper. On the left is the 3D area and on the right is the 2D area. For this article we will strike a middle ground with the barn star.Ĭlosing the splash screen shows you the basic interface of the application. On the right is a more complex 3D dragon that demonstrates some of the more complex things the app can handle. On the left is a simple cube partially unfolded with tabs for gluing shown. Pepakura Designer greets you with a bright splash screen that gives you a quick idea of what the application does for you. To keep the star in proportion, hold down the shift key as you drag out one of the corners. To create the star, drag out the star from the right-hand side and then stretch to about 100 mm. In TinkerCAD they have a barn star as one of their basic objects. All you have to do is sign up for a free account (), and if you have read other things I have written, you probably already have. For that we use the free web-based program TinkerCAD. To create a 3D paper model, it is easiest to start with a computer 3D model. And if the term barn star is new to you, check out Wikipedia. If you want to get into paper model making, this is a great place to start. A lot of Cosplay and Modeling people use it create very elaborate models from existing 3D graphics (from games, movies or sculptures) but you can also do less complex things easily that look really good. The good news is that is really easy with an inexpensive program called Pepakura Designer. Say a barn star with a color burst pattern? But there are lots of patterns on the internet, so add a computer and a printer to the list, but you probably have those already.īut what if you want to do something different. Cardstock, scissors and some glue and you are ready to go. Paper crafting is a fun and inexpensive hobby. Pepakura Designer (Not Free, but Inexpensive 38 USD). ![]()
