There is some pretty slick stuff coming down the pike in this Inventor Tutorial series including web configured components and a eco starter home with a designed-in upgrade path.
.
But for now, back to the Mission Table. The skeletal stuff is now complete, and all that’s left is to make components of the whole mess (47 solids). The image to the right shows the outcome … but for now, we have what you see below…
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… Continue reading
As stated in an earlier post, when modeling a multi-sold layout part, it is a best practice to reference only the skeletal geometry wherever possible.
.As you may be able to see in the image below, the yellow shelf plane was created via the line and point method at a point on the main elevation sketch that represents the top face of the shelf. The shelf boards were laid out early in the design process on the Layout sketch down at the bottom of the image. I always lay out all of the boards when designing Mission Furniture because generally the boards are book matched and often have butterfly splines between them. The boards in this case are book matched, but have no butterfly splines.
The modeling process for the first shelf board, as shown below, is simply to create a sketch on the plane that was just created, project the geometry that describes the board up to the sketch, and finally, extrude the shelf downwards to the point on the elevation sketch that describes the bottom of the shelf. That point on the image below is the next intersection down from the plane shown… Continue reading
The slats are one of the defining elements of the Arts & Crafts style as designed by the likes of Stickley and Frank Lloyd Wright. This is how I modeled them…
If you can’t quite see in the image to the right, click for the bigger one. What the image shows is the creation of a sketch plane using the line and point method, utilizing the Elevation 01 sketch to get a plane at the top of the stretcher. Again, it is very important to not begin sketches by clicking on a face, especially with multi-solid bodied layout parts such as this.
The slat is created in a similar manor to the stretcher and apron, albeit with less complexity. It is just a square stick with tenons on either end, and uses geometry projected from the same sketch that was used to create the slat mortises in the previous post: Mission Table Design: Modeling the Apron —as you can see in the image below… Continue reading
The Apron is modeled similar to the stretcher in the last article….neither will be completed until much later in the modeling process when more geometry is available.
The reason for this is that there is quite a bit of operations that happen to the tenon before it can be mirrored over to the other side. It will include the 13 slat tenons, which is the first pattern that goes beyond a simple mirror operation.
The body of the apron is created in the same way as the stretcher from yesterday’s article, and shares the same sketch plane. I’m not sure why I didn’t project this profile at the same time as I projected the one for the stretcher as it would have combined them into one sketch. Big dummy comes to mind 
On with the modeling…. As you can see if you enlarge the image above, the extrusion for the Apron uses the To option on the Extents dropdown, and the same point on the Layout sketch that was chosen when extruding the stretcher is chosen for this operation. Then the tenon is extruded in the opposite direction using the tenon portion of the same sketch. Continue reading
The stretcher for the Mission Table has quite a lot going on. There are the tenons on both ends that are chamfered and pin mortised, long through slot mortises for the shelf tenons with pin mortises from below, and the 13 slat mortises. Wow.
To begin modeling the stretcher, I needed to create Stretcher Plane 01 at the inside face of the leg that will become the shoulder of the tenon at that end. As I’ve stated before, I do not want to create a plane on the face of a solid body, so I create the plane by line and endpoint like the others as shown below. The solids are shown for reference only, their visibility was turned off before creating the plane… Continue reading
