This video shows the current progress on the BIM (Building Information Model) Eco Cottage (Blackhawk Cottage) currently in the works here at the Open Design Project. The video specifically shows the state of the routed systems such as the gas lines, the DWV (Drain Waste Vent) system, and the PEX plumbing.
I am hoping to have the water lines completely routed by the end of the week, and then jump over to the electrical, but I have quite a few other commitments this week so things may take a bit longer. Enjoy the video and have a great day…
In fine woodworking, square holes are as common as round ones. So why is it that none of the popular 3D parametric design programs include the option?
The answer is that they were created as Mechanical Design software with metal in mind. Inventor, for instance, can be used to create anything under the sun — but its modeling tools have always had a bias towards designing metal entities….until recently. Two versions ago, a set of plastic specific tools were added to the standard version of Inventor, marking the first non metal or generic toolset to make it into the program. I don’t work much in plastic, but it was a great day nonetheless.
But what about wood?
Well…..there are no wood-specific tools Inventor, and for the most part, there is no need for them. The one feature I would include (and the subject of this article) is a square hole option………… and I believe that it should live right there on the hole dialog (image above) with the round ones. After all, square holes are a reality in woodworking, and Inventor is about more than just metal. Yes? Continue reading →
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…
Today’s parts and the top are the last of the major components that need to be directly modeled. Most he rest of this piece is patterned from here…
If you’ve read the previous articles in this series, you know that whenever possible I create my new sketch planes on sketch geometry that resides on the Layout (plan view) or other skeletal geometry, and this part of the model is no exception.
The side stretcher below was, again, created from a sketch that is shared with the tenon. In the image, the tenon is shown being extruded, and if enlarged, you can see that the Extents is set to ‘To’, and a point where the front apron’s tenon and the side apron’s tenon meet is being selected as the stopping point.

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 →
