This is a follow-on for a previous GCI task:
http://www.google-melange.com/gci/task/view/google/gci2012/7977231
Your task is to take that tutorial, review it, and post it to our wiki. There are a couple minor issues to correct and at least one omission. Read through the whole tutorial and verify that it works (RUN THE STEPS). Add any clarifications / corrections that you find are needed. Here are a few that we notice:
- Step 10 doesn't say or show what the obj-g command actually is.
- When uploaded to the wiki, the mged command and graphics windows in section 11 need to be smaller, about quarter-size (not cropped). Both together should be the same size as the Blender window. Place them side-by-side.
- The MGED windows are disproportionately big, should be smaller or cropped to the area of interest in sections 12, 13, 14, and 15 (the command windows, too much white)
- Move the output image in section 16 into section 15 after the raytrace control panel so we end off with just the rendering in 16
- Third and fourth sentences are wrong. It is compatible, it's rotated. Say this instead:
Do you remember what your table looked like when you finished building it in Blender? It was upside down and now it's on its side. Rotating the table reorients it correctly:
sed default.1.1.b.c.s
rot 0 -90 0
accept
[insert another final rendering]
Then you can add this in a box with the diagram at the end:
"BRL-CAD, like most of the CAD industry, uses +Z for up. Blender, like most of the film industry, uses +Y for up. Using +Y for up has origins in the film industry where the image screen is the center of attention, X and Y form a view plane and Z is the depth or distance from the camera. Using +Z for up has origins in manufacturing and architecture where the object and scene are the center of attention, X and Y form a horizontal ground plane, and thus Z becomes the elevation or height dimension."
Add the cleaned up and reviewed article to our wiki at http://brlcad.org/wiki/Tutorial/Blender_to_CAD
Be sure to also add a reference to the tutorial on our main wiki page.

The claim on this task has been removed, someone else can claim it now.
Note that the commands shown to rotate the model were a rough guess -- they should be verified. You might want to make one leg shorter when testing just to make sure the table is oriented correctly.
The last image should be the table rendered and looking like it was in Blender when we started, so we can say something in closing like "With that last rotation, the import is complete!" Or something like that. ;)

I'm new to both Blender BRL-CAD, but I think I'll be able to follow the tutorial easily. I am not new to writing tutorials and making wiki articles, so that sould be a breeze.
One quick question; how do I do the actual translating? When I give the command translate obj-g, it says database not open. When I try to open the obj file, it says that's not a valid database. How does this work?
actually, when I try to open the obj file, it says "(null) (units=mm)".

I'm not understanding your question. What section of the tutorial, what parapgraph or sentence are you referring to? There is no translate command. The obj-g command is external to mged and creates a .g file that mged will read. If that's not clear in the tutorial, you should help make it clear since that's what this task involves.

I don't think I know enough about BRL-CAD to be able to do this.

Hello Sean,
Near the end where it says "Then you can add a box with a diagram in the end: ....."
Do you want me to take what you said word for word or do you want me to change it?
Also I do not understand the last bullet point.
Thanks,
Toshita

Hey Sean,
I have done everything but put my tutorial on wiki. I decided to check it with you before I put it into wiki. My document is attached to the task. Please tell me if I missed something.
Toshita
Toshita,
That's looking great. Yeah, word for word is better for the last paragraph. It looks like you're still missing the final rendered image of the table after accepting the rotation edit -- that's the final result image. The word for word paragraph will go into a box as a caption like the sketch image box here: http://brlcad.org/wiki/Sketch
Other minor change:
"Rotating the table reorients it correctly. Enter these commands in the command window:"
The deadline of the task has been extended with 1 days and 0 hours.

Toshita, do you need more time? All that's missing is one image, the paragraph, and the wiki upload.
Agent Um, what are you doing?
Hi Sean,
I am having tiny little issues that I am starting to fix when I am uploading in wiki. I have never worked with wiki before so I am learning as I go. I think I will need a little bit more time. I have put in the image and the paragraph, but only the wiki upload is left.
Toshita
I have a question. You said that the files can't be too big, so I resized my Blender files to 75%. But there is one problem, it is really hard to read what it says, so do you want me to keep it small or do you want me to keep the images in the original size?
Toshita
Hey Sean,
I put all the pictures and text into the wiki. I just need to finish the sketch image box and resize some of the pictures.

Toshita, reclaim the task so we can credit you with the completion. Looking at the wiki page, I see everything except for the coordinate system box (with that final paragraph as a caption).
The images look good except for the first two blender images look blurry (the rest look fine). Keeping them in their original size is fine (and displaying them scaled/smaller on the tutorial page). On that same point, the images in section 16 could be scaled down too (keeping the full size image in the wiki, but displayed smaller on the tutorial page).
Perhaps that's all what you were referring too. Looking great!
If you join our brlcad-news mailing list, you'll get to see the announcement when we share your tutorial with our community (sometime later this year).
