Boundary – Enables you to select the outermost boundaries of a quilt.Surface loop from-to – Enables you to select a range of edges from the surface loop.Surface loop – Enables you to select a loop of edges on a surface.Tangent chain – Enables you to select all the edges that are tangent to an anchor edge.One-by-one – Enables you to select adjacent edges one at a time along a continuous path.If you instead select the edges one at a time and round them, the round feature either fails or does not round the newly added edges. If the square cut is redefined into a hexagon cut, the intent chain automatically adds the two additional edges and rounds them because your intent was to round the edges of the cut. For example, you can use an intent chain to select the four edges of a square cut for purposes of rounding them. Intent chain – Enables you to select edges based on their intent.

The following are the different types of chains that can be used to select edges: Chains can be open-ended or closed-looped, but they are always defined by two ends. You can select multiple edges in Creo using different types of chains to increase efficiency and feature robustness.Ī chain is a collection of adjacent edges and curves that share common endpoints. We took notes and grabbed a few slides for you: Understand Advanced Chain Selection Matt Huybrecht from PTC University presented a quick overview recently.

You can use these different capabilities and approaches to select more robust feature references, or to more efficiently create geometry. Do you need to create complex CAD geometry? Creo supports several advanced techniques for selection that you should know about.
