"Apply bridging to perimeters" overrides perimeter speed

Maybe I'm not understanding how this should work, so it might be intended, but when you have the "Apply bridging settings to perimeters", the bridging speed multiplier *overrides* the perimeter speed multiplier, it doesn't multiply the multipliers. Ie, if you have perimeter speed multiplier 50% and bridging speed multiplier 50%, you get... 50% for perimeters that are also bridging, not 25% as I had expected.

Also, the "unsupported area threshold" doesn't seem to be working right. Even if I set this to many hundreds of mm^2, I still get loops marked as "bridging" in the preview that are only a few mm long.

Re: "Apply bridging to perimeters" overrides perimeter speed

If S3D detects a perimeter which actually is a bridge it treats it as bridge, depending on your bridging settings.
Why would anyone want to reduce a already reduced perimeter speed as mentioned above. Such a Setting most certainly would compromise everything.

Re: "Apply bridging to perimeters" overrides perimeter speed

I have just tested the bridging feature and it works exactly as I expected it to.

With the Apply Bridging to Perimeters box checked, the perimeters are printed as if they were part of the infill...ie at exactly the same speed.

The Unsupported Threshold also works correctly....areas below the threshold DO NOT get bridging applied and areas above the threshold DO get bridging applied. This is the opposite way to what I think you believe the setting works.

So then you agree that if I set the threshold to 500mm^2, nothing should be marked as bridging unless it's at least 500mm^2 in size, right? That is absolutely not the behavior I'm seeing on my model -- I'm seeing small individual loops of a few mm in length marked in yellow on the preview even with this setting in the hundreds of mm^2.
