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.
The 3D fit spline feature tool allows you to create a 3D fit spline through a series of vertices or edges that are tangential continuous. Click the 3D fit spline feature tool on the toolbar. Select the Vertices to form the spline. Check Closed spline if required. Click the green checkmark to accept the new spline. Alternatively, you can create a spline based on edges that are tangential continuous. Click the 3D fit spline feature tool on the toolbar, select Edges, and then select the edges to include in the spline. Click the green checkmark. A new Curve is created in the Curve list that is based on the new spline.
- Click .
- Click to select whether to use vertices, or edges at the top of the dialog.
- For splines using vertices:
- Click to select vertices along which to create the 3D fit spline.
- Optionally, check the box to create a closed spline.
- If the spline is not closed, you have the option to click a line or a Mate connector (implicit or explicit) to select a Start direction.
- Enter a value or click and drag the directional arrow in the graphics area to adjust the Start magnitude.
- Optionally, click to select Match curvature at start to match the curvature of the edge or face selected as the start direction.
- Optionally, click a line or Mate connector (implicit or explicit) to select an end direction.
- Enter a value or click and drag the directional arrow in the graphics area to adjust the End magnitude.
- Optionally, click to select Match curvature at end to match the curvature of the edge or face selected as the end direction.
- For splines using edges, click to select tangentially continuous edges with which to create the 3D fit spline.
- For splines using vertices:
- Click .
A curve is created, listed under Curves in the Parts list. You are not able to show/hide the 3D Fit Spline feature; use the show/hide functionality in the Curves (Parts) list instead.
- Click .
- Select edges (must be tangentially continuous) to create a 3D fit spline.
- Check the box to create the spline.
- Click .
- Click .
- Select vertices to create a 3D fit spline.

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.
