3D Model of a BIM Eco Cottage Showing PEX Routed Systems

Posted on by

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…

Open Design Project Status Report – BIM Eco Cottage

PEX Water LinesSorry for the limited posts lately, but I’ve been bogged down somewhat with the design of the Small BIM Eco Cottage, job searching, etc. The latest work on the Eco Cottage is the routing of PEX water lines.

The image to the right shows a close-up of the PEX cold water lines I am currently routing at a location near the manifold (click). Routing flexible lines such as this in Inventor is pretty is fairly simple. You place the fixtures or targets at beginning and end of the run, then place mounts and /or targets along the route between the two, then connect the dots with a 3D sketch.

In this case, unfortunately, I couldn’t find a single part as a BIM object, so I have to model them as I go. The image below shows the copper PEX manifold for the cold water. I modeled it as an iLogic part that can have between 2 and 24 ports with several manifold sizes, line sizes, and the choice of hot or cold (red or blue lines) configuration.

Creating a Routed System with Vanilla Autodesk Inventor – Phase Next

Posted on by

If you didn’t sleep through the previous post, you were promised some stuff at the very end. This is that stuff. It took longer than it should have as I had to get some drawings to the plumber. Without further ado…

The next part needed in this assembly is another 4” ‘Long Sweep’ elbow that goes somewhere below the circle that represents the closet flange penetration. To place this part, I needed to align the axis of one of its legs to an axis running through the center of the circle parallel to the Z Origin Axis. That axis does not exist, so I needed to create it.

.

A quick note about structure before I continue. All of the layout sketches and work features being created are located within the Plumbing Layout.ipt part file which is located within the Plumbing_08-25-10.iam. All of the plumbing parts are located in the same assembly as can be seen in the image of the Browser Bar to the above (click).

Creating a Routed System with Vanilla Autodesk Inventor

For this series of articles, the Routed System of choice will be your average everyday home plumbing. The DWV (drain, waste, and vent) system to be exact.  

The DWV layout I am using as an example is for is for a little eco cottage design that has all of the mechanicals running through chases and partition walls to keep the thermal envelope as intact as possible — but the technique will work on any design equally well. Also of note is that the design has a FPSF (frost Protected Shallow Foundation) slab……which means there is only one chance to get things right.

The Penetrations

The penetration drawing is a plan view sketch that shows where the various pipes pass through the structure at whatever level is represented. It is created  as the first sketch in a part file located in the overall plumbing assembly. This is a hold-over from ship design days, but it works on houses as well.  

For this particular house, you can see that the stack and vents run up a 2” x 6” partition wall. There is a wet vent at the other end of the wall as well, but is not shown. All of these penetrations run down the center of the wall, and can be drawn on the same plane, which is where I started.

Pella ThermaStar New Construction Window BIM Objects – Good to Go!

Posted on by

It’s been a busy few days filled with computer crashes  & glitches, email interviews, and a huge amount of hectic modeling  behind-the-scenes on a big fat house model.

Thanks to help from Mark Flayler over at IMAGINiT, the big culprit behind all of the crashing I have been experiencing has been traced to the Autodesk Labs 3DA technology preview… which makes sense I guess. Technology previews are not finished work where most of the buggyness like this is ironed out  before it gets added to a program, or —-in some cases just gets discarded. Think of Labs as a place where the programmers can throw their digital spaghetti against the wall to see what sticks. Sometimes you get smacked right in the face, but safe is for sissy’s ;)

 The Make Components Crash Fix

For those of you that have installed the Inventor 3DA technology preview and are experiencing crashing upon using the Make Components command, just go to Tools>Options>Add-Ins, select Inventor 3DA from the list, then uncheck the Load On Startup and the Loaded/Unloaded checkboxes at the bottom of the dialog as shown below…

Blue Giant Dock Equipment Now Available in BIM Format

Posted on by

Blue Giant Dock Equipment BIM ModelsBrampton, ON, Canada (July 2010)-Blue Giant Equipment Corporation now offers a complete library of Building Information Models (BIMs) for its products on Arcat.com.

Building Information Modeling (BIM) is the process of generating a building’s components based on inputted specifications, and then managing the entire project during all phases of construction and maintenance. It uses 3D, dynamic modeling software to create accurate, high-definition replications of building layouts and elements.

“The BIM of a Blue Giant product includes all its specifications,” explains Jeff Miller, Vice-President of Sales and Marketing at Blue Giant. “Architects can take the BIM of a dock leveler, vehicle restraint, or any type of dock equipment, drag it into their 3D building plan, and drop it into place.” Continue reading →
