Gaps in the model

[IGOR.GUDAC.IG]

Hi,

I don't know how to repair (or fill) the gaps in the attached model!

[TrippyLighting]

The gaps are the result of inappropriate modeling techniques, for example the excessive uses of boundary patches instead of proper 4-sided lofts. That is likely going to require a lot of re-work, if not a start from scratch.

The object (car model) was created using Surface Modeling. Each drawn surface was obtained by the patch (or loft) process. After the patch (or loft) procedure, Thicken command was applied to each individual surface. If the bodies are obtained at a sharp angle, gaps are formed between them at the joint. How can these gaps be filled?

FYI - there is no need to explain how the model was created.

The Timeline captured a history of the process.

Yep. A timeline including inadequate modeling techniques.

Does >>Lamborghini << (spelling corrected) use Fusion 360 for their body designs or do they use something like Alias or Catia or...

That would be utterly surprising, as you well know 😉

Even if they did, they would very unlikely use boundary patches to do so.

I do car modeling only as a hobby. I make models of various cars, about 30 cm in size. At the beginning of my work, sometime around 2010, I made models out of wood and exhibited some of them at the opening of the former Museum of Vintage Cars in Zagreb. A year ago, I started learning Fusion 360 in which I draw and then print models in 3D. I find blueprints with technical data on the Internet. So far I have made a number of less demanding models in the Solid Modeling technique, however this technique offers limited possibilities for making curved surfaces. That's why I started using the Surface Modeling technique, in which these problems with gaps appeared in my work, which I would like to solve, and I don't know how. If it is at all possible, I would like to repair this model (picture in attach, with marked gaps), rather than start over because I would most likely run into the same problem again. Can you give me some advice?

P.S. I really have no idea what program they use at Lamborghini for their designs 😊

As it pertains to this model I'd have to look at it into more detail, but I can already tell you that it's going to be a horrible hack working with the model as is. 

Going forward with new models I would suggest not to use surface modeling but T-Spline modeling. This is a completely different skill set and much more similar to Sub-D modeling in MoDo, Maya, Blender, C4D etc. There are many tutorials available for Car modeling  for Blender and all the other polygon modelers and often those are much better than the usual hobbyist/amateur created videos for Fusion 360.

The best source for car modeling in Fusion 360 using T-Splines is Gichi Endo's YouTube channel

Thanks!
