data conversion failed from curve to brep

Hey all! I am quite the newbie and I have probably a very basic problem that I have trouble solving....

The conversion from Crv to Brep seems not to be working. The weirdest thing for me is that it works only for 1 model, which was modeled in the same way all other ones that I am testing.

If you have ideas, please share :)

Hello Mihail.

If you attach the .GH file you are talking about it will be a lot easier to help you ;) You can either attach a rhino file as well with the stuff you reference or "internalise data" on nodes that reference a geometry from Rhino.

Otherwise there is no way to find out what the problem is in your case!

Hey Armin,

I am quite late with the reply thanks for answering anyway. I have been away for some time so still have the problem. I have attached the files. Take a look at the Brep to Divide cluster as I have indicated.

Thanks!

Hi Mihail,

your file contains components from a lot of plugins I don't have, so I can't reproduce the problem without installing them all. To avoid this you can internalise the data in the inputs that matter and remove all components to the left. This both simplifies file sharing and makes it more likely people can open the file.

That said, there's three reasons why Curve -> Brep conversions might fail:

The curve isn't closed.
The curve isn't planar (within tolerance).
The curve is invalid.

It should be fairly easy to detect whether (1) or (2) is the case, as there are components that test for closedness and planarity. It's also relatively easy to fix these problems.

If the curve is invalid, then you can use the [Null Item] component to inspect the data. I doubt the output under [D] is going to be helpful for anyone except a McNeel programmer though, but I'd like to see it if the curve is indeed invalid.
