Re: Silk: a NURBS workbench

I see your point, no problem from my side. Many thanks for explaining. The point is, from my point of view that FreeCAD needs something similar to Silk WB to be useful as a viable way to model thing in a "non hobbyst scenario". It is true that probably this tools must be written in C++ fo...

Re: Silk: a NURBS workbench

I agree that it's all about freedom, but I think that a simple use of a library to produce things, without altering the library itself should be "as free as possible" to spread the use of this library itself, and this should be clearly written in licenses. Understood, but Silk being curre...

Re: Silk: a NURBS workbench

LONG NOVEL WARNING - license only topic, regular users don't waste time reading. TL;DR: You can use FreeCAD to make commercial stuff and you keep 100% of the rights. If you change the code and want to sell FreeCAD - you have to release the code and attach the GPLv3 license to it to allow future user...

Re: Silk: a NURBS workbench

I wonder if a possible way to circument some problems is to define a solid using surfaces only. But this probavly involve to have tools that will build projections and joining surfaces to make the shell. This will be a math challenge. I've not managed to use Silk WB, (I've not very clear the GPL li...

Re: Silk: a NURBS workbench

... cross your fingers and try, but prepare yourself mentally to model the offset manually. After almost a decade of using FreeCAD, I know what you mean. 8-) i was hoping to see some kind pinch or collapsed lines in your grid i could point you to, but it really looks fine. not very evenly spaced, b...

Re: Silk: a NURBS workbench

The surface itself passes check, it is the Offset solid that fails. And, it is specifically the BOP checks and they indicate it may be fine if not used in following Boolean ops. But, I'd guess a lot of use cases would involve subsequent Booleans. I've never had problems using Silk surfaces for bool...

Re: Silk: a NURBS workbench

Are there rules of thumb or tricks to use while creating a surface to help avoid this? Same as all offsets. Keep local features 'large' in comparison to the thickness of the offset you intend to use. Offset can scale features in a way that they run into themselves. For polygons, edges collapse, for...

Re: Silk: a NURBS workbench

it's over really the top at this point, and not the best aesthetic, but the structure holds. makes it worth the effort for me. 5 sided shape_02_08.PNG . a massive change in the sketches may freak out the surface filling triangle . 5 sided shape_02_09.PNG . and when it freaks out, it's not fixable. h...
