A really really welcome new feature would be being able to create PDF 3D natively from rhino.
with tupport to layers, custom viewes, colours, layouting, line thickness and so on.
PDF 3D is really useful for didactics, and currently, to my knowledge, there is no proper affordable tool for this on the market. There are some which are subscription based, but creating PDF 3D is something that you don’t need to do continuatively so payng a subscription to do one PDF sometomes is not sustainable. It would be really awesome if Rhino had this integrated expecially because it already have all the tools to make a great PDF 3D (layouts, layers, 3D interactive views in layouts and so on.)
the use case of glb is completely different, I’m not interested into enporting a 3D file to import it into another software, I want to embed a 3D model into a handbook for students that they can use without prior knowledge of any software or even without any 3D viewer installtd. I know Pdf 3D is old, but it still has its nieche, it’s useful for me because every student has adobe reader in their laptops, even before installing any 3D software, and when explaining descriptive geometry, or any other subject where 3D shapes are part of the program, its’ super useful for them, because they are able to rotate and see in 3D the shape before drawing it in 2D by hand, and the fact that you can save specific views or layers allows you to preset the main piviewpoint, or split the drawing proces in steps by using layers so they can use it as a guide for drawing. pdf 3D even allows to add sections dynamically to the model, or show text together with the model and add it to normal text pages, so nothing I know has the same versatility and is already easily and locally accescible into any laptop without installing or learning new software peckages
Depending on what “proper” and “affordable” means to you, theres is SimLab’s 3D PDF-exporter. Really simple to use and 99$ a year is not a bad deal.
