I would use the Rhino mobile app at work every day and probably buy half a dozen copies a year for people who work for me IF… it could show dimensions.
When using rhino for fabrication, my current options for coördinating with the people who build and assemble what I design and build are to either send them screenshots by text message or send them print outs.
If the mobile app could show dimensions, I could go paperless and have a much easier time showing assemblers and fabricators what I want them to do.
We have a lot of turnover and a lot of part timers. This is common in the scenic, prop, trade show, and fashion show business. Buying every single worker who comes in my shop a copy of the mobile app would be worth the cost to me if it could display dimensions, and I can’t be the only digital fabrication guy who would see the benefit to this.
Don’t get me wrong, I think useful CAD on a phone would be a cool thing, but mostly a gimmick for collaboration.
What I mean is you could just send pdf to view on a phone easily. Of course if you want to spin a model that’s trickier in such a form factor of a device. And to create CAD with it also very tricky. Easier to sketch on a napkin (or a 'puter) and send pics of it for phone viewing. As far as designing on a phone, I have a very badass laptop and I don’t even like designing on that because of the tiny monitor, forget about a phone, rather have a pencil and paper than CAD on a phone, for actual use beyond being a cool gimmick.
It already is a thing. It’s called iRhino3D but it hasn’t been updated in ages.
I think there are two ways a mobile app could be utilitarian and more than just a gimmick (at least for my own workflow):
Presentation - If I could set views and snapshots on my desktop and have the ability to present from Rhino, maybe adding some notes along the way (text dots?), It could be really useful. This is much like the way I use Keynote for presentation–edit and refine on desktop and then present from a tablet.
Reference on-the-go - I currently have a stack of print outs on my desk–screenshots of models that I’ve quickly dimensioned–that I take with me to the shop to build. It would be helpful to just bring the 3dm with me on a tablet or my phone. I think this point is essentially the same as @Max3 's point --there’s no reason this couldn’t work collaboratively.
It’s very useful to be able to give assemblers/builders an exploded view, especially with complex props and setpieces.
In a lot of situations, it’s necessary and/or faster to do a build with a combination of CNC cut parts and hand cut parts. So if I can send the guys a dimensioned exploded view, color coded to show them what they’re building vs what I’m CNC cutting, it speeds everything up.
And it’s not very hard to take a design and explode it and dimension it. I’ve already got this part way automated for certain types of things we have to do a lot, like large prismatic letters or runs of 100+ different pedestals.
I completely agree. But wouldn’t you create these explodes, sections, callouts and such on a desktop and send them in pdf format, which they could view on a phone or any computer? Where in the workflow is the need to spin a model in 3D on a phone?
I use Autodesk Viewer https://viewer.autodesk.com/ to communicate with fabrication clients. The files are stored online, can be opened on any device and operating system. Dimensions are carried across with model. Has sectioning and exploded views, annotation, etc.
Doesn’t cost me anything.
make an account on grabcad.com and upload. The grabcad has built in 3d viewer and this viewer has function for displaying exploded view and measurement as well and that too by default !! what more you need ! Please check www.grabcad.com. I have used it on several ocassions.
