This is not Physics-based at all, you need to introduce other variables like wind speed around the drone, the direction of the wind, angle of attack, viscosity, etc. This example is parametric modeling at best or a configurator, not saying that is bad, just has a misleading title. I do not see any real geometry manipulation or groundbreaking CAD being attempted. Here is a viewer that Autodesk released this year using javascript.<p><a href="https:&#x2F;&#x2F;developer.autodesk.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;developer.autodesk.com&#x2F;</a>

It&#x27;s called parametric modelling, and many CAD software use a parametric kernel (solver). <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Computer-aided_design" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Computer-aided_design</a><p>Is this somehow different? Please explain

Nice project. What are you hoping to add in the future?<p>Our team works on goal directed design as well, but at the moment it&#x27;s less of an interactive optimization tool and more of an involved job running process a la Optistruct. One of our fun projects was a drone body as well :)<p>link for the interested: <a href="https:&#x2F;&#x2F;autodeskresearch.com&#x2F;projects&#x2F;dreamcatcher" rel="nofollow">https:&#x2F;&#x2F;autodeskresearch.com&#x2F;projects&#x2F;dreamcatcher</a>

Cool, I think more applications should be using solvers like this.<p>What solver are you using? Is it solved server side?

Interesting, do you have some more info about how it works? When I make the battery larger, is it considering the weight of the battery? Weight of motors, props, etc?

I managed to break the tool by inputting some infeasible inputs and then changing them again several times, and then refreshing the page.

this is more a configurator than a CAD.
