Aaron Maller, aka twiceroadsfool, has been sharing his Revit door family package on RevitForum for the past few years. If you haven’t seen it yet, you can check out his post in the thread here:
http://www.revitforum.org/architecture-family-creation/1242-doors-download-nested-panels-nested-frames.html

In the thread, he gives instructions on how the door families work, and a link to download the 179mb zip package:
First important part. The way they work is you only place the ones that say DOOR at the beginning of their name, obviously.

Download Link for the v4 Doors, a sample file with the doors in them, and the Door Schedule accompanying them, is here:

Thanks for sharing Aaron!

Did you ever notice this handy little selection toolset?

Pretty cool, huh?

Update: Dieter has correctly pointed out that these selection tools are part of the Bimits package:

The Advance steel addin can be downloaded for free:

I’m not saying that AceCad BIMReview is a great program, but its another free tool to keep in mind.

There is also a good list going at http://bimblog.bondbryan.com/interoperability/, which includes:
BIM Surfer (open source WebGL viewer)
Constructivity Model Viewer (PC only)
DDS-CAD Open BIM Viewer (PC only)
FZKViewer (PC only)
Solibri Model Viewer (PC and Mac)
Tekla BIMsight (PC, Windows tablets, iPad and iPhone)
xBIM Xplorer (PC only)

Anyhow, to try BIMReview Lite, download the installer at:
BIMReview – BIM Project Collaboration

Install ‘core’ only.

Switch to the free version by direct text editing this file.
“C:Program FilesAceCad Software LtdBIMReview 7.2BIMReview.exe.config”

Like this:

Or in Options:

I noticed some cutting errors when opening IFC from Tekla (the beam ends should cut back):

“nanoCAD is a well-proven DWG-compatible CAD program that includes AutoCAD-like APIs. It’s totally free. No catches. No adware. No crippleware. No incessant nagging. Up until now, the free version has been the only version of nanoCAD offered to the USA. No doubt, the best value in the industry (even better than DraftSight [it lacks APIs in the free version]).”

There is apparently over “20000 pages of documentation” that will be released, along with videos and 3D asset files.

It could be interesting to see how this release intersects with the development of Revit standards and Revit content globally…

The Autodesk Creative Commons “Area”:
AREA | creativecommons

“The group adopted the Creative Commons licensing which means 20,000 pages of documentation, 70 videos and 140 downloadable 3D asset files are now ready to be modified, remixed and shared globally.”

Autodesk makes huge trove of docs, training materials and 3D asset files available under Creative Commons – Boing Boing

As per the above Autodesk page, “More content to come soon…”

I have reposted Alex Vysotskiy before.  He recently uploaded a large set of Youtube videos, including a Basic Course and a course on the Family Editor.  See playlists below:

While editing a Group, you can’t create an Array.  There are two workarounds:

  1. Make the array ‘outside the group’ and then Add it to the Group.  This requires you to Finish Group, make Array, Edit Group, Add… etc
  2. You could use a line based Component as an array ‘guide’ to provide you with the intervals you need, and then Copy Multiple.  If you are in a Detail Group, use a Detail Component, if you are in a Model Group, use a Generic Model.

Here are some links to download my array guide components
These components have two instance properties – one to control the size of the ‘tick’, and one to control how many elements / divisions are in the array.
