One of the typical pain points in doing an FEA on long and thin models is that most automatic meshers will not create a mesh that will yield accurate results. A good example of this might be with trusses or similar structures.

Autodesk Algor includes a couple types of elements that can help us solve these situations. One is truss elements and the other is beam elements. These element types let us define the properties of the structural members in the design while only using line geometry to define the form.

CAD Geeks on the Road at AU 2009 – Part 1

This week a number of the CAD geeks will be in Las Vegas for AU 2009.
Please stop by the Tata Technologies booth #348 and say hello.
Below are just a few reasons to stop by our booth……for even more info and updates from AU consider becoming a Fan on Facebook
Tomorrow we will release more details of the Inventor CAD Geek Challenge you can do from your desk at work!





All my favorite videos (Autodesk Manufacturing related)

If you have been following the CAD Geeks blog, there are probably some videos on YouTube that might interest you as well.

Autodesk has its own channel with many different playlists available. A few playlists that I have learned from are listed below.

Just make sure you switch to the “Player View” in the upper right after using one of these links.

Two minute tips in Inventor: http://www.youtube.com/user/autodesk#grid/user/5F0BF9F1949DCC2A
My favorite is the Direct parameter name editing two minute tip.

Lifecycles in Vault Workgroup: http://www.youtube.com/user/autodesk#grid/user/E90F2AD408C2ED29
This gives you a good idea of the lifecycle based security in Vault Workgroup and Collaboration.

Panel Components – Mount and Group Codes

If you are a user of AutoCAD Electrical I am sure you are well aware of installation and location codes. If not a brief example is the ability to apply extra information to a schematic component to be used as a filter when generating reports, this is the most common example.

When we think about our Panel components we have two extra options available and that is the ability to add mount and group codes to our footprint data when working with panel layouts. They do not allow us to use them as a filter when generating reports for our panels but they do allow us to be use them as fields of information to be reported on when running a panel report for components inside of AutoCAD Electrical.

My example descriptions for each:

Mount – maybe a more defined location of a specific component like Back Plate, Left Side, Upper or Lower inside of a panel or control box.

Group – I think of this like being part of an assembly or kit inside of a design. Could be part of sequence of installation.

Again these are just my ideas please use as you will. Take a look at the short video below.

Let’s take a look!!!

Security Model example in Vault Collaboration

I have recently posted a bit about folder level security in Vault and how that can restrict people from changing data in locations they shouldn’t have access to. Potentially more important is the ability to use the folder security in conjunction with Lifecycle based security.

Take a look at the two vault interfaces in figures 1 and 2 below.

This first is a look at what an engineer or designer might see when logging into Vault:

This second image shows how a shop floor user or other viewer might see using the Vault Collaboration light weight web client:

Notice that the viewer has been configured to only display data that is a “Released” or equivalent state. This ensures that they are viewing only the correct data and at the right time in the files process lifecycle.
