During forward creation of sketched route segments, use the Parallel With Edge and Perpendicular To Face commands to reorient the axis of the 3D Orthogonal Route tool against existing geometry. When the next route point is defined on this axis, parallel or perpendicular constraint is added to the resultant route segment. You can also pick up route points in the other two axes.
Applying the two commands may request an irregular angle (neither 45-degree nor 90-degree) at the preceding route point. Consequently, a custom bend is created. Radius arrow and rotation arrow are available on the 3D Orthogonal Route tool. Edit the bend radius and rotation angle as you need.
Note: If you want to edit the orientation and constraints after a rigid route is finished, use the Constraints command, General Dimension command, and optionally Include Geometry command.
- In the route environment, if the 3D Orthogonal Route tool is not activated, do any of the following:
On the ribbon, use Route tab 
Create panel Route , and then click the last route point you just created. - In the Model browser or graphics window, click the last route point, and then click Route tab Create panel Route .
- In the Model browser or graphics window, right-click the last route point, and then select Route.
- Move the cursor over an axis of the 3D Orthogonal Route tool, right-click, and select Parallel With Edge or Perpendicular To Face.
- In the graphics window, click the appropriate edge or plane.
The 3D Orthogonal Route tool changes the orientation accordingly.
- To set the next route point, do either of the following:
- Move the cursor over the axis of the 3D Orthogonal Route tool, set the route point using the tooltip or Enter Distance command on the context menu. You can also pause the cursor over the axis and directly type a dimension value.
- Right-click and select Point Snap. Set the route point snapped from the appropriate geometry. The Point Snap command is typically applied together with the Rotation Snap command.
Tip: If it is on the axis involved in Step 2, use the Show Constraints command on the Route tab or Show All Constraints on the context menu to verify the parallel or perpendicular constraint on the new route segment. - If the included angle is neither 45-degree nor 90-degree, a bend is created with bend radius displayed. Edit the bend radius as needed.
- Continue picking route points to create more auto route regions or sketched route segments.
- To complete the route, right-click in the graphics window and select Done.
- Right-click again and select Finish Edit.
