Moderator's Note: This thread was started by Sean O'Brien (Sean_OBrien) in this thread:
This is only the first post in the thread. The original thread is still open for questions, comments, and discussion.

First part of this goes from 3D to paper. I have an appointment in a bit, but I will go ahead and post the paper model to laser cutting template.

That is the basic structure. Nothing too fancy, just a simple adobe building with a front door, back door, few windows and a set of stairs that go up to the roof. Might be used as a store front, cantina, or something like that. It isn't based on any particular building, just something to show my process.

You can find the 3D file here:


It is a zip file of an OBJ 3D file. Most 3D software packages can open it readily. If you are interested in looking, but don't have any 3D programs to take a look - you can get a hold of http://www.blender.org/ or http://www.wings3d.com/ for free. The building is in real size in millimeters in that file.

With that file, I scale it to the size I want. In this case, 1:48 and then save it back out. I open the file in Pepakura and then use that tool to unfold the model to create the paper model which you can find here:


That will print at 1:48 with no resizing on standard letter sized paper (I forgot to double check the margins for A4 paper...so those on the other side of the pond may need to double check that).

The paper model lets me do a quick check of size and figure out lines of sight and positioning of the model. If I need to make any changes to the model, I can do that cheaply and easily at this time.

I put the information together on a blog type post here:


That has the links to the software I used for this particular part of the process (one free and two commercial software packages - though I am not tied to any of them).

Later this evening, I will go ahead and put together the laser cutting guide which will be a bit more detailed as there is less information readily available on that particular step (Pepakura has pretty good tutorials, and 3D design is found all over the place).
