Hello Bao

This is not an error. If you look closely you will notice these are the curves that describe the intersection between these two brep sets. So i believe for this case the brep brep intersection component is not the best way to go.

You can do the folowing

you can start by using curve curve intersection. This will output the point where the initial contours intersect. Between these point you create a line that is in the center of the intersection taking place between the two breps. Then you can find the middle points of the lines with evaluate curve at 0.5 an these are the base points for the cylinders with height enough to be bigger than the brep that describes the structure, and radius same as the offset which is the width of each element. Then bounding box for these cylinders to get boxes for solid difference with the rib elements. Trim tree is used to bring the bounding boxes tree structure having the same path indices with the breps that you use for solid difference.

Cheers

Thank you sir.
