U.S. Patent drawing help
show user profile  joelr

I need to make a few drawings for a U.S. Patent application.
The drawings have a certain look to them- with a lot of lines that show the the surfaces.
Here is an example:

Usually I make drawing straight from solidworks but I can't get this kind of look.
I don't know any way to get this look In max.
Do any of you know a way to get this look with max, or what other software do they use for it?

For the flat-but-not-aligned perpective, try this on a few boxes: a camera set to orthographic with a Skew modifier applied to it.
I know it's not what you asked but it should help with the look.

Vray Toon defaults will give you the edges...this is overlaid over the AO pass.

For the shading /cross hatching maybe a PS filter / method on the AO layer. ?

Arkvis Sketch seems to be the daddy.


Rough and ready but you get the gist: I just darkened the AO layer and ran the cross hatch filter over it.

What about using a gradient ramp for the shading, I'm pretty sure you can tweak it to tile black-white-black-white etc (though haven't tried it).

Toon layer + AO layer. Use as mask for generated noise with direction blur in Photoshop + sharpen?

Yep, masking, using whatever makes sense.
You can also generate the parallel lines with a gradient ramp mapped to the screen/camera and a lot of tiling. Easy to orient.

Do US Patent applications have to look like they were hand-drawn?

Beware the patent office, if you have a revolutionary idea that will help with things like moving away from heavy oil consumption, for instance, they have a tenancy of killing you.

"While plane crashes do happen and scientists do die, Behar’s name has now been added to a very long list of scientists and astronomers who have met their untimely ends prematurely, leading us to ask, did Behar know something that ‘they’ don’t want the rest of society to find out?"

Holy shit, people actually truly believe this garbage.

Yeah, I know. Saw this in some video. Also said that Einstein was the head of this scam.

To be fair though, there have been cases of scientists getting killed for making super-efficient engines and trying to tap into free energy. But sites like this... pretty sure they're created to discredit all of it.

Thanks for trying to help guys, especially FX- that's a great technique I'll sure use it sometimes.
But my idea was to look for something that will be quick and easy. FXs technique will take a few hours for me to do and I was looking for already had that kind of a "hand drawn" look to it.
Maybe a different software I don't know...

For now I just added a bunch oF parralel lines in Photoshop to my drawing that I made in solidworks. Looks close enough. Took 5 minutes...

Is there any particular reason all patent sketches need to look like doodles on a napkin? why not just a standard orthographic + perspective illustrated schematic.. with you know.. colors and shit?

i don't know- i made "regular" looking line drawings, and the guy that is preparing all the information for the patent in the US returned it to us- wanted it to look more like the reference.
i also read the patent guidelines and they are hard to figure out
