Frame with Raised Panel and Mitered Sticking

The following tutorial assumes that the reader has the 2D proficiency necessary to draw closed profiles and is familiar with these 3D tools: 3D Box, Normal Extrude, 3D Intersect, Imprint, and Facet Editor. An understanding of the Mirror Copy tool is also needed.

Panel.pdf - A printable version of this tutorial.
Panel.tcw - The v9 TurboCAD drawing I used to generate this tutorial. It contains the final results and the required layers and named workplanes. For reference, there is also a profile layer containing all of the 2D objects I used to generate the solids. To use the drawing to start your own, just turn off the profile and results layers.

Tutorial:

1. Here is an exploded view of the tutorial's end result.
2. At the origin, start with two profiles on the construction layer: one that describes a top view of the stile (blue profile) and another that describes the top view of the left edge of the raised panel. Feel free to modify the profiles to suit your needs.
3. Position a copy of the profiles rotated 270° about world Y as shown.
4. On the 3D layer, snap a stile extrusion as shown.
5. Do the same for the remaining profiles.
6. Intersect the two panel extrusions to form a panel-corner.
7. Using the front view, snap the green profile on the construction layer. This profile describes the final rail-stile joint line. Because the profile encloses the right end of the rail, it can be used to modify the shape of the stile and rail extrusions.
8. Using the subtract option, imprint the new profile on the stile extrusion. Using the intersect option, imprint the new profile on the rail extrusion.
9. Turn off the 3D layer. On Layer_0, snap a 3D box that describes a top view of the rail tenon.
10. Snap a 3D Box that describes the end view of the rail tenon.
11. Finish the rail tenon by intersecting the two 3D Boxes.
12. Turn on the 3D layer and add the rail tenon to the rail. Using the keep-subtrahend option, subtract the rail from the stile to form the mortise. Slice off 1/16" from the end of the tenon for glue allowance. Note: At this point, you can save the result as a symbol to be used to quickly draw a completed panel of any dimensions.
13. Turn off the construction layer. On the Front workplane and Layer_0, draw a rectangle that describes the finished dimensions of the frame. Hidden-line render and redraw the screen ([F5]). Mirror-copy the rail, style, and panel corner by snapping the mirror line to the midpoints of the top and bottom of the rectangle.
14. With the Facet Editor, Snap the right-end facet of the left rail to a corner of the left-end facet of the right rail. Repeat the operation on the panel corner.
15. Add the two rails together. Repeat for the panel-corners.
16. Mirror copy the rail, stiles and panel by snapping the mirror line to the midpoints of the left and right sides of the rectangle.
17. Using the Facet Editor, snap the top faces of the stiles and panel to a corner of the bottom facet of a top stile. Perform the necessary 3D additions.
