When you sketch the profile of a feature, you can create new edges by projecting existing edges from the part onto the sketch sheet. You can use projected edges to duplicate the shapes of existing features as they appear from the current sketch plane. To project part edges, including orphan element edges, onto your sketch; select Add
Edges from the main menu bar.
To project edges:
From the Sketcher toolbox, select the Project Edges tool 
. For a diagram of the tools in the Sketcher toolbox, see “The Sketcher tools,” Section 20.4.1.
Abaqus/CAE displays prompts in the prompt area to guide you through the procedure.
If desired, toggle off Constrain to background in the prompt area to project the edges as independent objects.
If projected edges are constrained to the background, their shape and position depend on the original feature edges. If projected edges are unconstrained, changes to the original feature do not affect them—you can edit the projected edges and vertices independently from the original feature.
Select the edges you want to project into the sketch plane.
Click mouse button 2 to indicate you have finished selecting edges.
Abaqus/CAE creates the new edges in the sketch.
