What you'll need to do is change the way Windows handles .jar type files. You can right-click on the file, and go to Open With ... to see what program it's currently using to open it, and change it to Java, or alternatively, you can use this method:

Hmmm ... how about this, just to check that everything is working fine, even if double-clicking on it doesn't work:

Open up the Windows Command Prompt (In XP, go to Start Menu, All Programs, Accessories, Command Prompt)

Go to the directory that contains the java.exe file. I used this command:

Code: Select all
cd "c:Program FilesJavajre1.6.0_07bin"


I'm using the latest version of Java 6, hence the 6.0_07 above. You might need to substitute your exact directory there.

Then, place the oripa031.jar somewhere easy to access, for example, place a copy in the C: directory.

Now type the following command:

Code: Select all
java -jar c:oripa031.jar


That should run it, even if double-clicking on it doesn't.

Most origami artists use other programs to make crease patterns and diagrams. A quick search on the forum for diagramming software will come up with a lot of suggestions, for example:
viewtopic.php?t=4597

I'm not sure how to answer your question about how good they are in comparison to Oripa. Other programs are much more general. Oripa is specialized to origami, and specifically for drawing crease patterns. It's quite intuitive and fast to use. But, exporting it as a picture is not easy, and it can't draw diagrams.

I don't know too much about other software, so I can't comment too much on them.

JRE 5.0 is ok
To be able to start the jar file by doublecliccking on it you need to download and install also Java 3D 1.5.1 API (as suggested by the author in his webstite :wink: )

Here the dowload page for Java3D

I was able today to import an Oripa generated .dxf file into AutoCAD, and all the colors were preserved, as opposed to when I import it into Google SketchUp. I then was able to save the CP as a JPEG and other image file types.

By the way, for the forum members who are students, you can download a free student version of AutoCAD at the website of Autodesk. As a warning, it takes forever to download it and install.

What happened when you tried the Windows Command Prompt method?

I have problem. Oripa didn't show simulation effects only this statistic pop-up window do anyone know what to do with this? There is no error message, and I install all necessary libraries.

Definitively this software has some problems

It has just told to me that a simple square base (valley diagonals and mountain median) it is not foldable :shock: :?:

And this time I've checked carefully not to exceed from the square borders and not to have any wrong fold.

I think it is good for CP tracing since its origami-oriented drawing tools, but not for simulating.
