Countersink shown incorrectly in Broken-Out Section View – Bug or Feature? - Fusion

JB_SGGW — Mon, 17 Nov 2025 16:45:01 GMT

I believe I may have found a bug in the program's operation. Perhaps other users have already reported a similar issue. I created a model of a transparent base with four holes for countersunk screws on the top surface and four inscriptions on the bottom surface.

Based on the model, I created a drawing. The main view shows the component from above (top view). I made a broken-out section view (A-A) passing through one of the countersunk holes. In the section view, the countersink appeared on the bottom surface side, even though it is on the top surface in the model. As a test, I created a second section view (B-B), this time a simple straight one, and in that case, the countersinks were shown correctly.

Is this a bug, or do I not fully understand the rules for creating section views

Hello,

Unfortunately, no one has responded to the reported issue, and I haven't been able to find a solution myself. Moreover, I've noticed further errors.

Regarding Section A-A: I created a different cross-section, A-A. This time, Fusion correctly displayed the outline of the holes in the cross-section, but vertical lines appeared (marked by red circles in the drawing).

Regarding Section C-C: I made yet another cross-section, C-C. This time, Fusion created a section view that seems to be an unfolded (or developed) view—it appears wider than the parent part.

My question is: Why is this happening?
