Wish: AutoChain edge for PlanarSrf


I guess the topic says it all, PlanarSrf would benefit from an autochain edge option.

Hi Jorgen - Chain does work though - have you used that?



Hi Pascal, no, how do I use that? It’s not an option in either v5 nor v6 as far as I can tell.

Oh… hidden treasure… who the heck comes up with the idea to hide these gold nuggets? wow. What other commands are chain usable for? And please add it as an option to all those commands.

Hi Jorgen - typing ‘chain’ & Enter at the command line starts curve chaining any time chaining makes sense when Rhino is asking for curve input - like in DupEdge or PlanarSrf etc.



It’s just like the hidden “crv” option in join where you can join edges into a separate curve… good stuff like that should be in the gui imo, so please add it as a request :slight_smile:

Hi Jorgen - I think Chain was added so that adding command line options all over the place would not be needed. I do get that it is not ultra-discoverable by itself. It is certainly possible to at least add a button in Curve Tools or something as a step in the right direction, but this is one of those things that returns ‘Unknown command’ if used by itself - maybe that can be changed. Anyway, I’ll look into what we can do…

SelChain already exists on a button and can exist on its own without the ‘unknown command’ error. (I’ve always used just Chain, which works when Rhino is looking for a curve but not on its own). But clearly SelChain is not enough since a vet like you did not know about it.




…which works how & does what?

Hi Peter - anytime Rhino is looking for an object you can type in ‘crv’ and Enter to force the selection to only consider curves - this means, for instance, to take one of its more useful applications - that in Trim you can click on the edge of a surface and Rhino will select the edge curve and not the surface or polysurface.



Oh thanks - I’ve heard of that but haven’t tried it yet.
