No Way To Flip Direction of Hole Tool In "From Sketch" Mode

No Way To Flip Direction of Hole Tool In "From Sketch" Mode

I'm trying to add some holes to a body using the Hole tool in the "From Sketch" mode, but the default direction of the holes is down (toward the bottom origin plane) and the body I want to make the holes in is up above the sketch plane. Fusion 360 will not let me flip the direction of the holes to fix this. I can't drag the arrow past the 0 point like I normally could for an extrude. I can't change the depth to a negative value. There is no option to "flip" the hole direction. Fusion just assumes holes always go down, and there seems to be no fix.

Please add a "flip direction" option to the hole tool when in "from sketch" mode!

Arh, any closer and it would .....




Will work if there is a body to cut into.


Might help....

Ugh I don't know how I didn't see that there! I feel like it used to have the words "flip direction" instead of just using a little icon. Anyway, that's it, thanks! It is strange that you can't achieve the same functionality by pulling the arrow past the 0 point like you can with extrude.

By the way, I have same problem about this matter. Because I am facing this situation on my Python script. Does anybody know how to flip direction of hole by using Fusion360 API.

        distance = adsk.core.ValueInput.createByReal(5)
         hole = holes.add(holeInput)

Python pop up helper says that " The natural direction of the hole  opposite ....."   and this script generate opposite direction of hole. I want to flip direction of hole by API. Anybody advise me !

Hi @ysz77jp .


It seems that you can change it with the HoleFeatureInput.isDefaultDirection property. 


I came up with a process like this.


def initHole(
    plane1: adsk.fusion.BRepFace,
    x: float,
    y: float,
    z: float,
    diameter: float,
    depth: float) -> adsk.fusion.HoleFeature:

    comp: adsk.fusion.Component = plane1.body.parentComponent
    holeFeatures: adsk.fusion.HoleFeatures = comp.features.holeFeatures
    holeInput: adsk.fusion.HoleFeatureInput = holeFeatures.createSimpleInput(
        adsk.core.ValueInput.createByString(f'{diameter} mm')
        adsk.core.Point3D.create(x, y, z)
    distance = adsk.core.ValueInput.createByReal(depth)

    holeFeat: adsk.fusion.HoleFeature = None
        holeFeat = holeFeatures.add(holeInput)
        holeInput.isDefaultDirection = not holeInput.isDefaultDirection # here
        holeFeat = holeFeatures.add(holeInput)

    return holeFeat


Initially, the default direction will be used, and when an exception occurs, the opposite direction will be used.

Thank you, that screen shot remains very helpful, the current icon is slightly different, still gets the point across. 

It is odd that the blue direction arrow will not allow a mouse move to reverse, as it does in many other commands
