Intersection Curve

With two or more surfaces or faces that intersect in the graphics area:

1. Click .

   

2. Group 1 is automatically highlighted. A group is a collection of surfaces and/or faces from which intersections are created. Select the first group of surfaces and/or faces in the graphics area.
3. Select Group 2 in the dialog.
4. Select the second group of surfaces and/or faces in the graphics area.
5. Click to accept.

Intersections between entities in the same group do not generate a curve, only intersections between Group 1 and Group 2.

Depending on the selections for Group 1 and Group 2, more than one curve can be created.

An example where two intersecting surfaces result in the creation of 3 curves

Use the eye icon in the Parts (Curves) list to show/hide the curve.

• If you create a Linear pattern from an intersection curve, the curves may not be created along the surface. If you instead want them created along the surface, open the Linear pattern feature dialog, add the plane used for the intersection in the Features to pattern, and check Reapply features.

  

In addition to the surfacing tools, curves are used to create the basic building blocks of surfaces.

This lists the collection of curve feature tools. This is not an exhaustive list. Additional Feature tools may be used when manipulating curves.

• Sketch tools - Tools in the Sketch toolbar such as Line, Corner rectangle, Center point rectangle, Center point circle, 3 point circle, Tangent arc, 3 point arc, Spline, Point, and Construction used to create a sketch in a Part Studio.
• Helix - Create a helix using a conical or cylindrical face, single axis or z-axis of a mate connector, or circular edge.
• 3D fit spline - Create a 3D fit spline through a series of vertices. Creates a curve which is listed in the Parts list under Curves.
• Projected curve - Create a curve from the projection of two sketches (Two sketches option) or from the projection of a curve on a face (Curve to face option).
• Bridging curve - Create a Curve connecting any two points, vertices, or Mate connectors. The resulting Curve is listed in the Feature list and the Parts list.
• Composite curve - Represent multiple edges as one Curve. Select multiple adjacent edges, sketch entities, and other curves. Selecting non-contiguous edges may result in multiple Curves created. Selections for each Curve must meet at their vertices. (Curves are listed in the Parts > Curves list.)
• Intersection curve - Create a curve at the intersection of two or more surfaces or faces. The selections must intersect.
• Trim curve - Trim or extend a curve by a distance or to a bounding entity.
• Isocline - Create an isocline on a sloped face. An isocline runs on a face at positions where the face has a certain slope compared to its reference definition. The resulting isocline is listed in the Feature list and Parts list.
• Offset curve - Create and extend and/or split a new curve by offsetting edges on surrounding faces.
• Isoparametric curve - Create smooth curves that run along a face or surface in the U or V direction.
• Edit curve - Edit an existing curve by selecting sketch entities or curves to apply a simplified approximation, elevate the degree, reposition control curve vertices and/or planarize into any 2D plane.
