Learn how to use the Project command to project geometry from outside the active sketch onto the sketch plane so that you can reference surrounding features in a design as you define a sketch in Fusion.
On the Sketch contextual tab, select Create > Project/Include > Project .
The Project dialog displays.
In the dialog, select a Selection Filter:
In the canvas, select the bodies, faces, edges, or points to project.
Optional: Uncheck Projection Link if you don't want to maintain an associative relationship with the selected objects.
Click OK or press Enter.
The selected objects are projected onto the active sketch plane, and display as purple projection geometry.
In the Sketch Palette, check or uncheck Show Projected Geometries.
If you change the objects you projected from the design and the associative relationship is broken, a yellow warning displays on the Sketch feature in the Timeline to indicate the Projection Link is lost. The affected projection geometry is highlighted orange or yellow in the canvas.
In the Timeline, right-click the Sketch feature.
Select Manage Lost Projections.
The Manage Lost Projections dialog displays.
In the dialog, select a lost projection.
Select an Operation:
Repeat steps 3-4 for each lost projection.
Click OK.
The associative relationships are re-established, broken, or deleted in the active sketch.
