Extend Surface

  The following options are available for extending surfaces.

Extend Curve to Surface Method

Extends selected curves to selected surfaces. The following methods and options are available.

  • Closest

    Projects the selected curve(s) to the selected surface(s), and creates new surface(s) normal to the selected surface(s).

  • Tangential from edge

    Extends a surface edge to the selected surfaces in a direction normal to the selected edge. The extension follows the curvature of the original surface.

  • Tangential along U/V

    Extends a surface edge to the selected surfaces in the u or v direction of the original surface.

  • Trim surfaces

    Attempts to trim the selected surface(s) to form a T-connection.

  • Tolerance

    This value is the build topology tolerance.

Extend Surface at Edge Method

Extends a surface at the selected edge.

  • Surface

    Select the surface to be extended.

  • Curve

    Select the edge at which the surface is to be extended.

  • Extension

    The relative length of the extension. A value of 0.2 defines an extension of 20% of the original surface.

  • Absolute distance

    If this is toggled ON, then the Extension value is taken as an absolute distance instead of a relative factor.

  • Trim surfaces

    Attempts to trim the selected surface(s) to form a T-connection.

Close gaps between midsurfaced parts

This function requires connected regions of surfaces to be in separate parts. For each part selected, the single edges are checked for their proximity to the surfaces of the other parts. If the proximity is within the specified distance, it will attempt to extend the surfaces in the same way as the Extend Curve to Surface Method.

  • Parts

    Select the parts that the surfaces belong to.

  • Dist.

    Enter the maximum gap distance to be closed.

  • Method

    • Closest

      Projects the selected curve(s) to the selected surface(s), and creates new surface(s) normal to the selected surface(s).

    • Tangential from edge

      Extends a surface edge to the selected surfaces in a direction normal to the selected edge. The extension follows the curvature of the original surface.

    • Tangential along U/V

      Extends a surface edge to the selected surfaces in the u or v direction of the original surface.

  • Preview Vectors

    Displays the possible vectors of the surface extension. You can select individual vectors to Exclude or Include.

  • Extension Arrow Size

    Select the vector arrow size.

  • Trim surfaces

    Attempts to trim the selected surface(s) to form a T-connection.

  • Tolerance

    This value is the build topology tolerance.
