Extract Edges from Solid Extract Edges from SolidThe Extract Edges from Solid function allows you to select one or more solids or surfaces to extract the edges and create wireframe curves. This function uses whole solid picking and extracts all edges of the selected solids or surfaces. To extract edges using single selection, use Extract Edges Single.
TIP: It is helpful to create a new layer and set it as the Active layer, before opening the function, to create the extracted curves on the separate layer. Otherwise, you must hide, move, or delete the original geometry to see the curves.
To open Extract Edges from Solid, do one of the following:
In the Utilities menu, point to Extract Edges and click From Solid.
On the Utilities toolbar,
click the icon.
Right-click anywhere in the graphics area, point to Utilities, Extract Edges, and click From Solid.
The parameters display in the 
Data Entry tab
of the Data-CAM Tree Manager.
Select the check box to project the extracted edges to a specified Z-axis
coordinate of the Active UCS.
Clear the check box to extract the edges without projecting them. The
extracted edges retain their exact position on the geometry.
Z - is the Z-axis value to which the edges are extracted when using Project to Z Plane.
NOTE: Be aware that using Project to Z Plane for solids may result in duplicate entities being projected to the same location. You may need to delete or cleanup the extra geometry.
You may want to create a new Layer and set it as the Active layer before extracting edges. This makes it easier to hide and show layers so you can see and use the result.
1 Open the function and set the Data Entry parameters if needed.
2 Click to select one or more solids or surfaces from which you want to extract the edges.
3 To confirm the selection, press the Spacebar. (You can also click OK to confirm the selections.)
The edges are extracted and the wireframe is created in the graphics area.
You may need to move, hide, or delete the original geometry to see the extracted edges.
4 To close the function, click Cancel.
