T-Spline model failed to convert

3DRBT — Wed, 31 Jul 2024 23:18:52 GMT

Hi everyone, I´m not that experienced yet with sculpting in the form modus and can't seem to get rid of the stars and other errors I encounter. I understood that you need 4 sides to every face and kept to that rule, but still some stars and T-spline errors keep appearing. Can someone please have a look and tell me what I´m doing wrong? Many thanks in advance. Cheers!

I don't think I would model that boat with T-Splines and I'll attach a similar model from another thread, that uses a surface modeling approach.

Having said that, there are only three small changes I made to this T-Spline model of which only two are needed to convert this:

Thanks for the solution. This worked for me. Can you perhaps elaborate a bit on how you would approach this. I started out with some sketches at first but found it difficult to integrate the various shapes. Cheers!

I assume you are referring to the model I mentioned in my post but then forgot to attach.

Thanks again. I tried using sketches and extruding those to a solid but just can't seem to get the same results as when using the Form tool. I feel like I´ve come a long way though with the last Form body I created. The repair tool is only showing 4 stars in the back which should not pose a problem according to what I´ve learned about the error messages. But still it fails to convert T-splines to Brep. Is there any way you can have a quick look at that one and tell me what I´ doing wrong? Many thanks in advance!

I usually categorically refuse to look at models that don't have a timeline. I'll make an exception in this case because its a T-Spline model.

I took a quick look and there is more broken than meets the eye. I'll take a more detailed look tonight.

Thanks brother. I very much appreciate it!

As I already mentioned, there is quite a bit to untangle in this model.

In the end, I was able to fix the geometry problems and get it to convert into a Surface body. However, I think creased edges and T-Junctions can be problematic.

I forgot to explain how to fill in that area I delete right in the beginning of the other video:

Wow! Peter thank you so much. You are amazing! In these 2 clips I've learned more about the whole process then I could imagine. The thing is that the error messages stated by Fusion are sometimes so cryptic that it's almost impossible for a beginner to pinpoint where the exact problems are. Anyways you have been a tremendous help. If you're ever in Amsterdam or the Netherlands in general, hit me up and I'll gladly buy you a beer! Cheers mate!

I might take you up on that. I visit the German side of my family once a year and that's only 30Km from the Dutch border 😉
