On the other hand, t-points are areas where faces converge to make a t-shape. When a t-spline is converted to BREP, it will split into separate surfaces at each star point. Star points also determine how a t-spline will be converted to BREP. But, if a star is red, there may be a problem with an edge/face not being tangent or collinear. If the star is yellow that means everything is good. A star-point is any point that has 3, 5, or more faces all converging at a single point, essentially making a star shape. To briefly explain the star-point errors. If it does detect some errors, you’ll typically see the color of your stars change from red to yellow. If you click “Repair Body” and it doesn’t do anything…that’s great! That means it’s not detecting any t-point or star-point errors. After you select the t-spline body you’re given the option to toggle on and off the different error labels to check. Then, you’ll first have to select the t-spline body as depicted in the dialog box. Select “Repair Body” from the “Utilities” dropdown list. The repair body command may not be able to fix your self-intersecting errors, but at the very least it will let you know if your t-spline model has any t-point or star-point errors.

It looks like I pushed or pulled too far, causing the edge or face of the padded area to collide with the faces of the headband.Īfter you take note of where your errors are located you should check the “Repair Body” command. If we take a look at this headphone model that I sculpted, you’ll see that I have the self-intersecting error on both sides of the headband. If your model is symmetrical then you can turn on symmetry to fix multiple errors at once (more on this later). I recommend tackling each error one by one unless your model is symmetric. Depending on your model and error, you may end up having more than one spot that needs to be fixed and that’s okay. Then, take note of the errors on your model. Put simply, Fusion 360 won’t allow this to happen because two things can’t really exist in the same exact space.įirst, hit the “finish form” button in the Fusion 360 toolbar. It’s caused by faces that intersect with other faces. This specific t-spline error is pretty self-explanatory. When the error message comes up in the lower right-hand corner, you’ll see that it highlights the problem area of your model in red.

The first thing you should understand is what the error means and why it happens. Whether you’ve imported a t-spline model from another program, or you’re trying to convert your sculpted form into a solid body, getting the “self-intersecting t-spline error” can be super frustrating.
