Using the 3D Polyline tool
The 3D Polyline tool is similar to the Polyline tool, except that you can create a polyline by specifying coordinate points in three dimensions. Also, you can only create straight lines using this tool.
Change the Visual Style of the model to Wireframe.
Click Home > Draw > 3D Polyline on the ribbon.
Select the center point on the front face on the cylindrical object.
Move the cursor toward right and select the center point on the back face of the cylindrical object.
Press ENTER; the 3D polyline will be created.
