How do I prevent the random deformation when convert file from T-spline to B-rep?

So I made a model in t-spline format, when converted to solid, it suddenly have a bunch of random deform on the surface and at the edge. It is completely random no matter what I tried, they don't disappear

I circle them in red:

That is hard to answer in detail without the model. My guess is that the T-Spline model has less than ideal topology in those areas. If you can attach you .f3d file, then I might be able to provide more detailed feedback.

For reasons that should be blatantly obvious, I need the original T-Spline model.
The model you shared dose not include the T-Spline.

Sorry my bad

This is the T-spline version

I think what you see is just a visual artifact stemming from Fusion 360's adaptive Level Of Detail algorithm.

If you right-click on the solid body in the browser and then select Display Detail Control and change it from :adaptive" to "fixed/high" these artifacts will disappear and your edges are crisp.

Thank you a lot, it seem like what you said totally correct
after doing like what you said, the deform disappear
