Use the Split Face tool to create an edge on a face or surface by splitting it with another face or edge. You can use the new edge to modify the face independent of previously attached geometry.

To create an edge on a face

  1. Click Split Face in the Intersect group on the Design tab.

    The Select Target tool guide is enabled.

  2. Select the face you want to split.

  3. (Optional) Select a tool guide.

    Mouse over faces or edges in your design to preview the edge that will be created on the target. Dimensions are displayed along the U and V edge of the face.

  4. Click to select the face, plane, or edge you want to use to split the selected face. You can select multiple faces.

    You can hold Shift and hover over an edge while selecting the cutter points. The midpoint on the edge will be marked with a yellow ball in parentheses. The x and y dimensions will emanate from that point.

  5. The Select Results tool guide remains active until there is only one split line remaining, so you can remove all but one split line without reactivating the tool guide

Tool guides

Within the Split Face tool, there are several tool guides that help step you through the splitting process:

The Select Target tool guide is active by default. If you did not pre-select the target face or surface, you can select it from within the Split Face tool using the Select tool guide. Ctrl+click multiple surfaces or solid faces in the same plane to split them all.

The Select Cutter Face tool guide activates once you select a target. When this tool guide is active, click to select the face or surface you want to use to create an edge on the target.

The Select UV Cutter Point tool guide activates once you select a target. Mouse over an edge to preview the new edges that will be created. Click to create the edge on the selected face. You can mouse over an edge with this tool guide to display and edit the length along the edge, and the percentage of the edge that is between the first point and the end point.

The Select Perpendicular Cutter Point tool guide activates once you select a target. Select an edge to preview where the perpendicular split will be made. Click to create the edge on the selected face. The face is split perpendicular to the edge you select.

The Select Two Cutter Points tool guide activates once you select a target. Click to select the first point on an edge, then mouse over another edge to preview the new edge that will be created. Click to create the edge on the selected face. The shortest line is drawn between the two points. You can mouse over an edge with this tool guide to display and edit the length along the edge, and the percentage of the edge that is between the first point and the end point.

Select the Select Results tool guide, then click newly created edges to remove any edges you don't want to keep.
