The Mission Table Model: Wrapping up the Skeletal Modeling

Just the corner bracing, top, and some square pins left to model, then it’s mostly patterning from there on in … and a bit of chamfering to finish things off.

  The highlighted geometry you can see in the image to the right is the projected sketch that was used to create the corner brace. The lines seen stabbing into the aprons are representations of the screw holes that will come shortly. One of these same lines was also used to create the plane that the screw and bolt sketches were laid out on.

  The hole layout sketch is mostly constrained to projected geometry, with only the two dimensions shown below added to the equation. There are Equal constraints, Coincident constraints to projected points, along with Horizontal and Vertical constraints to create a fully constrained sketch. As per usual, here is no geometry projected from solids…

.

All of the holes are drilled as clearance holes in the brace itself, and minor shank diameter holes are drilled in the target parts behind. The screws anchor into the aprons, and the hanger bolt into the leg assembly…

Now, a center plane was created on the layout sketch for the square tenon pins to mirror the lower pin up to the upper mortise…

..and the results…

The top was very simple. The outline was already laid out in the Layout sketch, so I projected two of the corner points up to the table top sketch, and drew a two point rectangle between them.  I divided the top into five boards, split the lines at the ends of the boards to create the continuous loops, and put Equal constraints between all of the end lines on one side…

One of the sections was then extruded using the Top_Thickness parameter for the extents…

13 Mirrors, 1 Pattern,  and 2 Chamfer operations later, and the skeletal  modeling is complete.  All of the mirroring was done using the origin planes, so there is not a lot to show. So I won’t. It was likely 5 to 10 minutes of work.

As I said in the last post, the Make Components operation is next, and I hope I can wrap things up in a post or two. Have a great day…
