ADN DevCast Episode 3

Once again, members of the DevTech Americas team have put together an entertaining and informative DevCast session on AutoCAD's APIs. This time, Gopinath Taget joins Stephen Preston and Fenton Webb to present a number of interesting topics: boundary tracing, associative surfaces, 3D laser scanning and point cloud filtering.

I'll be covering boundary tracing via this blog in the coming weeks, just as I expect to be doing more with point clouds (coincidentally a laser scanner from FARO – similar to the one Fenton and Gonzalo use in this DevCast – should be arriving for me today, so watch this space :-).

If you prefer you can download this episode for offline viewing (74.1 MB) and take a look at the accompanying samples (62 KB).

Enjoy! 🙂

Hey guys, nice DevCast.

First, my favorite API funcion is close() because it means you have finish some loop and can test it. 🙂

Ok, I have some questions about Point Clouds for you:

Suppose you have scanned a table (as you did) and want to generate a surface (a face, shell or mesh) from it. It would be just a matter of analyze the coplanar points and use them to generate those entities? What about more organic objects like fancy chairs?

I think the Point Cloud is a fantastic input but how much better would be converting the cloud into AutoCAD entities like faces, meshes, regions, etc.?

Can you elaborate on this?

Best regards.

Hi Fernando,

Creating more useful objects whether automatically or semi-automatically from point clouds is certainly desirable functionality.

There are indeed partners who provide this kind of functionality (although I haven't used any such product, myself).

And, as you know, I can't comment here on Autodesk's plans (even confirming whether or not they exist) for products that have not been announced publicly.

Regards,

Kean
