trimmed t spline form caused by errors

Anonymous — Fri, 03 Jan 2020 13:09:41 GMT

Hi everyone, i started to model t-spline since one week and now i spent two days trying to fix this problem. My design (photo 1)

in the create form environment don't show problem but when I convert it to a body, it lose most of the faces (photo 2)

giving to me lot of errors. I tried toopen an old version of the same design without the back of the car (photo 3)

and it works despite some errors (photo 4).

I tried also to match the back of the car to the rest and borns the same error of the ultimate design of the firts photo. When I was sculping I deleted some bodies and probably it caused some of errors but i don't understand how to fix it. I tried to re import the deleted bodies but i can't name them with the old name cause of the pogram don't permit it. So if someone can help me I really appreciate.

Can you share your design (public link to it from the data panel ) ?

If you disable download, all I can do is look at "something" in a web viewer.

I really need access to a downloadable model to I can inspect the browser, the T-Splines and the timeline.

Looking at your design I can see that you are following a workflow that has been propagated throughout many well meaning but uninformed tutorials. I would never work with a T-Spline model in such a way as is is inherently and evidently brought with a number of problems.

1. There are quite a few triangles intros T-Spline, which should all be removed.

2. You should model this almost completely in box mode as it is much easier toe see any problems.

The reason so many of your surfacing commands fail is likely that you edited the T-Spline and then the rest of the model "fell apart". The reason is that you changed the topology of your T-Spline. If you do need to use surfacing to model then you should do that after you are fully satisfied with the T-Spline and only very minor modifications are needed.

Oh, thank's. I'm new with t-spline. I will study better all this workflow

This series of YouTube tutorials is the only series I can hotly recommend for vehicle modeling. Gichi Endo is a professional vehicle designer and has taught classes at Autodesk University.

These videos are not narrated but like with every true artist, the work speaks for itself!
