Make a Patent Drawing

Hello everyone. Is it possible to add to 3D Max the possibility of Making a Patent Drawing for patent requirements, like Solid Works? 3D Max is so a handy and flexible app for this matter but there is no Appropriate render for Patent Drawing.

Honestely, such features are rather the strength of a typical CAD software. e.g. Inventor -> IDW/DWG

Can you define the required elements of a Patent Drawing? I am seeing mostly a hidden-line rendering in orthographic view, which you should be able to do in 3ds Max with the right renderer. The placement of the annotation lines and numbers might need manual work.

So I went ahead with this idea and used the "toon" shader in Arnold to render something like this:

Also attached is a .max file for 3ds Max 2023, hope this helps.

Hi. Do you know how we can use the default max (paint shade material) but just for selected edges only It works for simple objects, not for complex ones.

Are you referring to the "Ink'n Paint" material available for the Scanline renderer?

 

I would need some more detail on what you are trying to do (do you have a screenshot?) but I am not aware of a direct way to "select" or "tag" specific mesh edges; this sounds more like you would need to use those edges to create some special "line" geometry that uses a dedicated "line" shader.

 

Most NPR shaders I know try to automatically detect the edges to use for line drawings, based on face angles, material IDs or object IDs.

 

So what you maybe could do is assign different Material IDs to the polygons/faces on either side of the edge you want specifically to be drawn, and then instruct the shader to draw lines around Material IDs?

Here is a more complex example (imported IGES data), again rendered with Arnold:

yes ink material with scan line and how we can include or exclude some edges by material ID? The ink material always works for the whole object.

is it possible for some wanted surfaces to have sketchy effects like black pencil drawings?
