A computer-implemented method for planning an orthopedic procedure including positioning a virtual implant component relative to a 3D volume of scan data of a patient, comprising generating a first 2D view of scan data based on a 3D volume of the scan data , which includes scan data of a bony anatomy of the patient; defining relative to the first 2D view of scan data first positional information for the virtual implant component ; generating a second 2D view of scan data based on the 3D volume of scan data , wherein the second 2D view of scan data is provided from the 3D volume of scan data at an angle relative to the first 2D view of scan data; defining relative to the second 2D view of scan data second positional information for the virtual implant component ; and providing 3D positional information for the virtual implant component relative the 3D volume of scan data based on the first positional information and the second positional information; characterized by positioning orientation objects in said first 2D view and said second 2D view for aligning 3D volume of scan data with the first 2D view and the second 2D view; wherein said providing 3D positional information for the virtual implant component is based on the first positional information and the second positional information for orientation objects positioned in said first 2D view and said second 2D view, and said defining relative to the first 2D view of scan data and defining relative said second 2D view of scan data comprises defining at least one affected anatomy space by positioning at least one position object relative to at least said first 2D view of scan data and said second 2D view of scan data. generating a first 2D view of scan data based on a 3D volume of the scan data , which includes scan data of a bony anatomy of the patient; defining relative to the first 2D view of scan data first positional information for the virtual implant component ; generating a second 2D view of scan data based on the 3D volume of scan data , wherein the second 2D view of scan data is provided from the 3D volume of scan data at an angle relative to the first 2D view of scan data; defining relative to the second 2D view of scan data second positional information for the virtual implant component ; and providing 3D positional information for the virtual implant component relative the 3D volume of scan data based on the first positional information and the second positional information; characterized by positioning orientation objects in said first 2D view and said second 2D view for aligning 3D volume of scan data with the first 2D view and the second 2D view; wherein said providing 3D positional information for the virtual implant component is based on the first positional information and the second positional information for orientation objects positioned in said first 2D view and said second 2D view, and said defining relative to the first 2D view of scan data and defining relative said second 2D view of scan data comprises defining at least one affected anatomy space by positioning at least one position object relative to at least said first 2D view of scan data and said second 2D view of scan data. <EOS>
