Hi,

Could somebody point me in the direction of a sample using sketch intersections from within FS please?

Thank you.

    Intersection with another sketch or a face/body? Usually surface extrude and split is in there somewhere.

    Hi @NeilCooke,

    I need to find the intersection of faces with the sketch plane, once I have those points I need to create a spline between them.

    Copy the body/face, split using the sketch plane, get the split edges (which will be lines or splines).

    I don’t think I accurately described my use case.

    I've created a test document at:

    https://cad.onshape.com/documents/7c6ca2bc23d02b723929713c/w/29063b52b480481857e92a03/e/ad5ab431f37e97b51f03d91c

    The use case is to create longerons for fuselage formers.

    I've created one manually using a frame and it is that which I want to automate within the feature.

    Thank you.

    Can you not just use the intersection of the plane and the "Skin"?

    I'm not sure how to go about this?

    The Boolean tool doesn't allow sheet parts to be selected when intersecting which means that neither the skin nor plane are selectable?

    Do you have an example of what you mean which would generate the line I need for the frame path?

    Thank you.

    Can't you do this with an intersection curve?
    In 3D you could use https://cad.onshape.com/help/Content/intersectioncurve.htm..

    On a plane you could open a sketch and use the intersection tool (dropdown below 'Use (project/convert)')
