Hallo,

how can I trace (as curve or sketch too) the intersection between a plane and a surface in an assembly? Creo Parametric 2.0.

Thanks

    You'll have to first make a planar surface at the same location as the datum plane. Then you can use the intersect tool to create the curve where the two surfaces intersect.

    Based on previous responses, I was unclear. Apologies. Try this.

    Pic of two parts assembled together. Yes, this is a crude view, but it's only to get the instructions done.

    Part1 is the greenish part. Part2 is the greyish part. You can see the datum plane (from Part2).

    For this exercise we'll be putting an curve around Part1 where the Datum Plane from Part2 intersects.

    Create an extrude, but make sure to switch it to Extrude as Surface. (I picked the bottom of Part2 as the sketching plane.)

    Pick the Datum of Part2 as a sketcher reference and sketch a single line. The ends of this line should fall outside Part1.

    Make the depth go through Part1.

    Make a copy of the geometry from Part1 you want to intersect. To do this, change your selection filter to Geometry.

    Select the geometry surface you want to intersect. You can select multiples using the Ctrl key.

    Copy/Paste using Ctrl-C/Ctrl-P. Note the stippled surface denoting a surface at the same location as that portion of Part1.

    Select the Copy and the Extrude created above.

    Pick Intersect from the Modifiers fly-out menu.

    Hide the Extrude and the Copy. You now have an intersect curve.

      Hi Don,

      thank you very much for your instructions. In fact it was missing the step of creating a surface with copy geometry of the intersecting surface of the other part.

      As an alternative to your extrude as surface there is also the possibility to use the command "Fill" with the datum plane as sketch plane: this way too needs creating a sketch so they are equally time taking...

      I thought the function intersect was working also simply with datum plane and geometry surface, but anyway that's good better than nothing.


      thanks

      bye bye

      An option that might work would be to create a cross section with that datum plane and then create a Datum Curve from Cross Section.

      There is always more to learn.

        Hi Kevin,

        thanks your suggestion it's interesting too and maybe faster, remains just an aesthetic problem with the entire curve from cross section view showing up once you create the curve from the section...if only it would be possible to hide all the chains you don't want to show and keeping only the portion you need....

        bye

        That would require making a copy of the curves you want and hiding the original curves in a layer.

        There is always more to learn.
