- I downloaded an armchair model, opened it in blender. This is the original wireframe form of this model.
2. I followed the steps in tutorial to reduce the face count of this armchair.
Select – Add modifier – Decimate
(The total face count is under 500)
3. I exported it as obj. file.
4. The next step is importing this file into Pepakura. But this app doesn’t have Mac version. Therefore, I found a substitutional app called Unfolder. (https://www.unfolder.app/download.html)
5. I opened my file in the Unfolder. I adjusted the paper size (A2), rearranged each part on the paper.
This is what I got finally.
I chose this project because I think it is much easier and faster for computer to calculate how many surfaces and joining parts you need to make when you are preparing a paper model. As long as you have the 2D version of your model, you can just print it, cut it out, and finally glue it into a 3D model.
