Model a hammer in 3D using BRL-CADBRL-CAD
Status: ClosedTime to complete:
168 hrs
Mentors: erikg
This task involves modeling a hammer in BRL-CAD. The hammer should be accurately modeled in such a way that it can be printed using a 3D printer. This means that the model should have no overlaps (use rtcheck and/or g_qa gqa commands to verify) and will probably consist of two or more regions. Create one top-level combination to group your regions.
The output of this task would be a rendered image and .g file of the model.

I would like to work on this task.
This task has been assigned to Sharan Narayan. You have 168 hours to complete this task, good luck!
The work on this task is ready to be reviewed.
The clawhammer model has overlaps. If you run "rtcheck", it will report which objects overlap. The overlaps should be inspected and fixed by adjusting sizes and positions. It's also preferred to use the implicit primitives instead of sketch+extrude objects unless it's a specific shape that cannot be easily modeled with the other primitives. It's fine for this one, but keep it in mind for any others you create (be creative, use a variety of objects).
The other hammer may have overlaps too, I didn't check it. Also make sure your dimensions are "accurate" this time... i.e., it's roughly the size of a real hammer. ;)
One of the mentors has sent this task back for more work. Talk to the mentor(s) assigned to this task to satisfy the requirements needed to complete this task, submit your work again and mark the task as complete once you re-submit your work.
The work on this task is ready to be reviewed.
I have had aldready increased the size of the hammers by selecting the group file from matrix selection and scaling it..
The clawhammer is about 13in and sledgehammer is about 10in.
The Overlaps are removed in the updated.rar..
Congratulations, this task has been completed successfully.
Sharan, these look good now, thanks!
I noticed that you set the handles to the "wood" shader, which is fine but what you probably wanted was something different. The "wood" shader by itself is going to be a solid flat texture. You still want to see curvature and depth, so you need more than wood. That is where the "stack" shader comes in.
You probably wanted a stack shader with wood and plastic. I'm not sure what archer currently does, but in mged under the shader parameter panel you can delete the wood shader, add a stack, and then add wood and then add plastic. Apply and re-rerender and it should look much better.
