You can offset individual edges and edge loops of 2D and 3D shapes with the Offset edge tool. This means that if you offset a single edge or sketch element, you can create a parallel edge, or sketch line or curve. If you offset an entire closed sketch or body face, a parallel copy of the edge (or sketch) loop is created.

Offset in 2D

If you want to offset in 2D mode, you can reach the Offset edge tool from the Sketch submenu. If you start sketching, the Sketch menu will automatically appear.

Offset a single edge or sketch element

Go to Menu > Sketch > Offset edge, and select a part of a closed sketch or an edge of a body.
Optionally, select the object and then Offset edge.
Choose “Single” offset type.
Drag the arrows in either direction to move the offset object.
Select the dimension label and set a precise offset value with the numpad.
Select an empty area of the grid when you’re done.

Offset multiple edges or sketch elements

Go to Menu > Sketch > Offset edge, and select a part of a closed sketch or an edge of a body.
Optionally, select the object and then Offset edge.

The immediate edge (sketch) loop is selected.
If you selected a sketch element or an edge that is shared by multiple fillings, then the edge (sketch) loops of all those fillings are selected.
Choose “Loop” offset type.
Drag the arrows in either direction to offset the loop.

If multiple loops are selected, then drag the arrows to offset one of the fillings.
Select the dimension label and set a precise offset value with the numpad.
Select an empty area of the grid when you’re done.

Offset in 3D

If you want to offset in 3D mode, you can reach the Offset edge tool from the Tools menu.

Offset a single edge or sketch element

Go to Menu > Tools > Offset edge.
Choose “Single” offset type.
Select one edge on the body.
Two sets of arrows will appear next to the selected edge, because that edge is shared by two planar surfaces.
You can also select a sketch line or curve to offset.
Drag the arrows on the planar surface of your choice.
You can offset in two directions along the first planar surface, and in two directions along the second planar surface.
Select the dimension label and set a precise offset value with the numpad.
Select Done.

Offset multiple edges or sketch elements

Go to Menu > Tools > Offset edge.
Choose “Loop” offset type.
Select a face or an edge of a body.
If you first select a face, the immediate edge loop is immediately selected.
If you first select an edge, then the edge loops that share the edge are immediately selected. In this case, two sets of arrows will appear next to the selected edge.
You can also select a sketch element to offset the entire sketch.
Drag the arrows on the planar surface of your choice.
If multiple edge loops were previously selected, then choose one edge loop to offset. You can offset in two directions along the first face, and in two directions along the second face.
Select the dimension label and set a precise offset value with the numpad.
Select Done to finish.
