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). Note that the projections from one sketch must intersect the other (sketch or face) in one contiguous curve for this operation to succeed. The resulting Projected curve feature is listed in the Feature list and the curve itself is listed in the Curves list. For best results when selecting a curve, use the Curves list.

The Projected curve feature allows you to 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). Note that the projections from one sketch must intersect the other (sketch or face) in one contiguous curve for this operation to succeed. Click the Projected curve feature on the toolbar. Select the first sketch. Click on the Second sketch field in the dialog and select the second sketch. Click the green checkmark. The curve is listed in the Curves list.

In the second example, click the Projected curve feature on the toolbar. Select Curve to face in the dialog. Select the edge. Select Normal to target. Click the Target field in the dialog and select the Target face. The curve is projected onto the target face normal to the target. Alternatively, select Direction. Click the Direction field in the dialog. Select the entity used for the direction. Then select the target. Click the green checkmark. The curve is listed in the Curves list.

With two non-parallel sketch curves in the graphic area:

  1. Click Projected curve feature tool icon.

  2. Select the Two sketches option.
  3. With focus in the First sketch field, select the First sketch (on the model or in the Feature list).
  4. With focus in the Second sketch field, select the Second sketch (on the model or in the Feature list).
  5. Click Accept checkmark icon to accept.

You can not show/hide the feature associated with a Curve; use the show/hide functionality in the Curves list instead.

The first sketch is selected:

  1. Click Projected curve feature tool icon.

  2. Select the Curve to face option.
  3. With focus in the Edges field, select the edge/curve (you can select multiple) to project onto a face.
  4. Select the perspective of the projection:
    1. Normal to target - Project the curve or curves onto the target face normal to the target.

    2. Direction - Select a curve or edge illustrating the direction in which to project the curve or curves.

  5. With focus in the Targets field, select the face (or faces) onto which to project the selected curves.
