Summary0003141: Unexpected behaviour using pad to face on padded shape binder
DescriptionForum thread: Bug? Mysterious over zealous pad to face

Pad extends far beyond expected face.
Steps To ReproduceRefer to attached file:

In body003, with sketch035 attached to either of the large flat faces of "pad matching lifter support"
Pad to dimension works as expected if "reversed"
Pad to selected, opposite, face gives an unexpected result. (Example attached)
Pad to first/last gives an error when clicking OK: "SketchBased: Up to face: No faces found in this direction"

By way of experiment, I tried to pocket the sketch. "Through all" looked correct, but other options ended badly.

Is it possible that is related?

The issue can be easily reproduced with the model issue3141.fcstd.
* Open the file
* Edit Sketch001 resize the rectangle so that the circle is completely inside
* Close the sketch
=> on the opposite side a long cuboid will be created

* Edit the sketch again and resize the rectangle so that it intersects the circle
* Close the sketch
=> the cuboid disappears

The bug lies inside the function ProfileBased::getUpToFace that doesn't return an unlimited UpToFace (see line 428ff). This makes BRepFeat_MakePrism::Perform to create an unexpected prism.
